    ABSTRACT: To evaluate the genotype distribution of a rare age-related macular degeneration (AMD)-susceptibility variant, complement factor H (CFH) R1210C, among a large Japanese cohort with AMD. One thousand three hundred and sixty-four Japanese patients with neovascular AMD were evaluated. We screened for CFH R1210C (rs121913059) by genotyping with the Taqman method; the mutation was confirmed by Sanger sequencing. We also searched for this mutation in the human genome variant database, which contains the whole-exome sequencing data for 1208 Japanese individuals. The detailed characteristics of patients with this mutation were reviewed. The mean age of the patients was 74.5 years (standard deviation 8.7); men accounted for 71.8 % of the patients. The CFH R1210C variant was found in only 1 of the 1364 AMD patients, and was heterozygous (minor allele frequency (MAF) = 0.037 %); it was not found in any of the 1208 individuals in the control group (MAF = 0 %). The patient with CFH R1210C was a 70-year-old woman whose main complaint was visual loss in the right eye. Dilated fundus examination, optical coherence tomography, and fluorescein and indocyanine angiography revealed polypoidal choroidal neovasculopathy (PCV), but no drusen in either eye. Despite treatment, her visual acuity had decreased to 1/50 by 6.8 years after her first visit. The CFH R1210C variant was found to be rare among Japanese patients with AMD. The patient with the mutation did have the PCV subtype, but no drusen formation. Considering their ethnicity-specific nature, such rare variants should be studied by use of next-generation sequencing for each ethnicity.

    ABSTRACT: To evaluate the outcomes of intravitreal liposomal amphotericin B (L-AmB) for treatment of endogenous candida endophthalmitis. Medical records of four patients with endogenous candida endophthalmitis treated with intravitreal L-AmB injection alone or combined with vitrectomy were reviewed. Endogenous candida endophthalmitis developed in two patients after gastrointestinal surgery, in one patient with sepsis, and in one patient undergoing systemic chemotherapy for metastatic breast cancer. Three eyes of two patients exhibited toxic uveitis following repetitive intravitreal injection of amphotericin B deoxycholate (AmB-D, 10 μg/0.1 ml). The other patients had general health issues that restricted the use of AmB-D due to the potential risk of systemic toxicity. Seven eyes underwent intravitreal injection of L-AmB (10 μg/0.1 ml) with or without vitrectomy. In these patients, intraocular inflammation and vitreous opacities resolved, and chorioretinal infiltrates evolved into fibrotic scars. Visual acuity improved and stabilized in all eyes during the follow-up period. Intravitreal L-AmB seems to be well tolerated and effective in the treatment of endogenous candida endophthalmitis, and may be a reasonable alternative for patients who cannot endure the side effects or toxicity associated with conventional AmB-D therapy.

    ABSTRACT: To investigate the outcomes of unilateral medial rectus resection (UMR-res) for the treatment of small to moderate angles of recurrent exotropia in children followed up for a minimum of 6 months. This study is a retrospective, consecutive, interventional case series in which 48 children who underwent UMR-res (range 4.0-7.5 mm) for recurrent exotropia [range 12-25 prism diopters (PD)] between January 2009 and February 2013 were enrolled. Of these 48 children, 32 had recurrent intermittent exotropia, and 16 had recurrent constant exotropia. A successful surgical alignment was defined as +5 to -10 PD of orthophoria in the primary position while viewing distant or near targets. At a mean follow-up of 12 months, the surgical success rate was 75 % (36/48), and the undercorrection rate was 25 % (12/48). No patient exhibited overcorrection. The success rates of the UMR-res in the recurrent intermittent exotropia group and recurrent constant exotropia group were 78 % and 69 %, respectively, and were not significantly different (P = 0.50). In the initial surgical procedure groups, the success rates of patients with bilateral lateral rectus recession, unilateral lateral rectus recession, and unilateral lateral rectus recession combined with medial rectus resection were 81.8 % (18/22), 81.25 % (13/16), and 50 % (5/10), respectively. The surgical success rates did not differ among these three groups (P = 0.122). Based on our results, UMR-res would appear to be an effective and safe procedure for the treatment of intermittent or constant recurrent exotropia of ≤25 PD in children.

    ABSTRACT: To compare the outcomes of 23-gauge (G) and 25G vitrectomy to 20G vitrectomy on eyes with severe proliferative diabetic retinopathy (PDR). The medical records of 424 eyes of 347 patients with severe PDR were reviewed. There were 80 eyes that had 23G, 174 eyes that had 25G, and 170 eyes that had 20G vitrectomy. The incidences of postoperative vitreous hemorrhage, intraoperative retinal breaks, retinal detachment, and neovascular glaucoma were compared. The incidence of intraoperative retinal breaks was significantly lower in the 23G group (21 %) than in the 20G group (35 %, P = 0.03) but not in the 25G group (26 %, P = 0.057). The incidence of postoperative retinal detachment was not significantly different among the three groups (P = 0.73). The incidence of postoperative vitreous hemorrhage that developed ≥1 month after vitrectomy was not different whether the eyes had panretinal photocoagulation or not (P = 0.15). The incidence of postoperative neovascular glaucoma was significantly lower in the 25G group (3 %) than in the 20G group (11 %, P = 0.01) but not significant compared with that in the 23G group (8 %, P = 0.72). The lower incidence of intraoperative retinal breaks and postoperative neovascular glaucoma after microincision vitrectomy indicates that microincision vitrectomy should be considered for eyes with severe PDR.

    ABSTRACT: To evaluate the occurrence of hyperemia with, and efficacy of, bimatoprost 0.01 % for patients in Korea previously treated for open-angle glaucoma (OAG; including normal tension glaucoma) or ocular hypertension (OHT). In this multicenter, observational study (Asia Pacific Patterns from Early Access of Lumigan 0.01 % in Korea; APPEAL Korea), patients with unachieved target intraocular pressure (IOP) despite previous treatment received bimatoprost 0.01 % daily for 12 weeks. The primary endpoint was incidence of hyperemia and its severity, graded using the standard 5-point photographic scale and grouped as "none to mild" and "moderate to severe". Hyperemia shifts were reported. IOP and adverse events (AEs) were recorded. Of 800 patients (intent-to-treat/safety population), 248 were switched from previous treatment to bimatoprost 0.01 % monotherapy. Hyperemia shifts from baseline at weeks 6 and 12 were unchanged (84.8, 89.8 %), improved (4.4, 4.8 %), or worsened (10.8, 5.4 %), respectively. The shift was significant at week 6 (P < 0.0001). Hyperemia did not worsen significantly in patients previously receiving a prostaglandin analog or prostamide (PGA/PSD). Baseline mean IOP ± SD was 17.0 ± 5.7 mmHg, decreasing to 14.6 ± 3.8 mmHg (P < 0.0001) after 6 weeks, and to 14.7 ± 3.6 mmHg (P < 0.0001) after 12 weeks. Patients switched from PGA or PSD (excluding bimatoprost 0.03 %) to bimatoprost 0.01 % experienced significant IOP reductions from baseline. Treatment-related ocular AEs were reported by 37 patients, the most common being hyperemia (7.3 %). This subanalysis of the APPEAL Korea study supports use of bimatoprost 0.01 % for previously treated patients with OAG (including normal tension glaucoma) or OHT who did not reach target IOP or were intolerant of previous treatment.

    ABSTRACT: To clarify the characteristics and outcomes of unusual retinal pigment epithelial detachments (PEDs). These PEDs had one or several sites of apparent thinning of the RPE, or no RPE at all, as shown on optical coherence tomography (OCT). Eight cases with PEDs showed apparent thinning of the RPE in the roof of the PED at one or more sites on OCT. Color fundus photographs, fundus examination records, fluorescein angiograms (FAs) and/or indocyanine green angiograms (ICGAs), obtained with simultaneous OCT using Spectralis(®), and fundus autofluorescence were evaluated. Macular findings, prior to baseline PED detection, were investigated in three cases. Follow-up results were also reviewed in three cases. Well-delineated grayish-white lesions at the level of the choroid observed through a hypo- or unpigmented area corresponding to the area of thinning in the RPE on OCT. These lesions showed intense hyperfluorescence due to staining on both FAs and ICGAs as well as hypofluorescence on fundus autofluorescence. In three eyes, smaller PEDs had been observed at the same locations and were thus taken as the baseline PEDs on images obtained 22-94 months before this study. In two of the three eyes followed up for at least 35 months from baseline, the PEDs collapsed, leaving RPE-choriocapillaris atrophy in one eye and RPE tear in the other. Lesions corresponding to the area of thinning in the RPE on OCT may indicate hypo- or unpigmented RPE, possibly as a result of focal damage due to longstanding PEDs. These PEDs may lead to unexpected complications during long-term follow-up.

    ABSTRACT: To compare short-term outcomes of Descemet's stripping automated endothelial keratoplasty (DSAEK) using a graft prepared with either a femtosecond laser or a microkeratome. Thirty-eight patients underwent DSAEK with grafts prepared with either a femtosecond laser (f-DSAEK; 21 eyes) or a microkeratome (m-DSAEK; 17 eyes). Visual acuity, endothelial cell density, regular astigmatism and irregular astigmatism were compared between the two groups preoperatively and at 1, 3, and 6 months post-operatively. Fourier analysis was conducted to calculate astigmatism of the anterior and posterior surfaces, and total cornea, using anterior segment optical coherence tomography (AS-OCT). Visual acuity (logMAR) improved from 1.20 ± 0.60 to 0.43 ± 0.25 after m-DSAEK (P < 0.001) and from 1.20 ± 0.57 to 0.77 ± 0.33 after f-DSAEK (P = 0.0028) at 6 months following DSAEK. Visual acuity after m-DSAEK was significantly better than after f-DSAEK at 1, 3, and 6 months (P < 0.05). AS-OCT corneal images revealed greater irregularities on the posterior surfaces of f-DSAEK grafts compared to m-DSAEK grafts. Irregular astigmatism of the total cornea and the posterior surface was significantly larger after f-DSAEK than after m-DSAEK, although there was no significant difference in irregular astigmatism of the anterior surface at 6 months. Postoperative visual acuity was significantly correlated with the postoperative irregular astigmatism of the total cornea (r = 0.6657 and P < 0.001) and the anterior (r = 0.416, P = 0.016) and posterior surfaces (r = 0.7046, P < 0.001). Visual outcomes after f-DSAEK were poor compared to conventional m-DSAEK due to an increase in irregular astigmatism caused by posterior surface irregularities.

    ABSTRACT: To examine the prognosis of patients with diabetic macular edema (DME) before Japanese approval of antivascular endothelial growth factor (VEGF). This retrospective study included 135 eyes of 115 patients who received treatments (photocoagulation, pharmacological treatments, vitrectomy) for DME between January 2003 and August 2012. The best-corrected visual acuity (BCVA) before and 1, 3, 6, 12, and 24 months after treatment was examined. BCVA was classified based on the decimal value of BCVA before treatment as good (BCVA > 0.7, BCVA = 0.7), moderate (BCVA > 0.7 but <0.2), or poor (BCVA < 0.2, BCVA = 0.2), and each prognosis of BCVA was investigated. Thirty-five (25.9 %) patients were classified with good BCVA, while 69 (51.1 %) had moderate and 31 (23.0 %) poor BCVA. Following 24 months of treatment, the averaged good BCVA maintained its value (0.0513 ± 0.0954 to 0.0773 ± 0.258). Similarly, the averaged moderate BCVA maintained its value (0.449 ± 0.169 to 0.441 ± 0.431), whereas the averaged poor BCVA significantly improved (1.070 ± 0.291 to 0.879 ± 0.361: p < 0.001). Specifically, the averaged BCVA of patients who initially received vitrectomy increased 0.380 logMAR after 24 months (0.859 ± 0.414 to 0.479 ± 0.549). DME patients with good BCVA at the time of initial treatment generally maintained the averaged BCVA at 24 months, while patients with moderate BCVA did not significantly improve without a standard regimen of anti-VEGF therapy. However, the results indicate that early vitrectomy is a potential treatment option for DME patients with poor BCVA.

    ABSTRACT: To examine the clinical utility of femtosecond laser-assisted astigmatic keratotomy (FSL-AK) for eyes after cataract surgery. Eight eyes of 6 patients with an intraocular lens and corneal astigmatism of 2.0 diopters (D) or more underwent FSL-AK. The mean preoperative manifest cylindrical refraction was 2.88 ± 0.64 D and the mean corneal astigmatism was 2.84 ± 0.83 D. Paired symmetrical arcuate incisions were created with the same settings, except for the incision depth. Uncorrected distance visual acuity (UDVA), manifest cylindrical power, and surgically induced astigmatism (SIA) were measured at 1 day, 1 week, and 1 month postoperatively. Fourier analysis of corneal topography and incision depths measured with anterior-segment optical coherence tomography were evaluated 1 month postoperatively. In all eyes, the UDVA improved at 1 week and 1 month postoperatively, and the manifest cylinder also decreased postoperatively, while the SIA showed overcorrections in 6 eyes. Fourier analysis showed decreases in spherical and regular astigmatic components and increases in higher-order irregularity. The mean incision depth was measured as 60 µm deeper than the intended depth. The FSL-AK effectively reduced corneal astigmatism and improved the UDVA, although it was demonstrated that the deeper incisions led to overcorrection.

    ABSTRACT: To investigate anatomical responses and visual changes in cases of exudative age-related macular degeneration (AMD) with choroidal vascular hyperpermeability (CVH) that responded poorly to multiple ranibizumab injections and were treated with intravitreal aflibercept. Retrospective comparative study. Twenty-five consecutive patients attending the outpatient clinic of the University of Tokyo Hospital who showed an insufficient response to multiple intravitreal ranibizumab injections and were switched to intravitreal aflibercept injections between March and June 2013. All patients were treated with intravitreal aflibercept in a treat-and-extend regimen and followed up for at least 12 months. Presence or absence of CVH was determined by indocyanine green angiography. Changes of best-corrected visual acuity (BCVA) and central retinal thickness (CRT) at 12 months were compared between the CVH (+) AMD and CVH (-) AMD eyes. The improvement in logMAR BCVA at 12 months was larger in the CVH (-) AMD eyes than in the CVH (+) AMD eyes (-0.18 vs -0.026; P = 0.0089, t-test). The changes in CRT did not differ significantly between the groups (-122 ± 101 μm in the CVH (-) AMD eyes and -159 ± 118 μm in the CVH (+) AMD eyes; P = 0.44, t-test). The proportion of the eyes without intraretinal or subretinal fluid or hemorrhage was 88 % in the CVH (-) AMD and 67 % in the CVH (+) AMD (P = 0.21, t-test). Compared with AMD without CVH, AMD with CVH showed poorer visual gain resulting from intravitreal aflibercept treatment.

    ABSTRACT: To understand the current practice pattern for the surgical treatment of congenital/developmental cataracts in Japan. A mail questionnaire was sent to facilities engaged in thesurgical treatment of congenital cataracts in Japan. Thirty-four facilities reported their preferred methods for the surgical treatment of congenital cataracts, including data from 809 eyes of 508 patients who had undergone surgery. More than 85 % of the respondents answered that they would consider surgery even if the visual prognosis was not promising because of possible form-deprivation amblyopia. The most commonly performed surgical maneuvers were scleral tunnel incision (88.4 %), 3.0-mm or smaller incision (78.8 %), manual anterior continuous curvilinear capsulorhexis (90.2 % success rate), posterior capsulotomy (92.5 % for patients aged ≤6 years), anterior vitrectomy by the limbal approach (85.9 % for patients aged ≤6 years), and wound closure with sutures (93.2 %). Posterior capsulotomy and vitrectomy were not usually performed in patients aged >6 years. Implantation of an intraocular lens (IOL) was mostly indicated in patients aged 2 years or older. Implantation of an acrylic foldable IOL (76.6 %) into the capsular bag (89.7 %) was the most common practice among the surgeons. Small incision surgery with implantation of an acrylic foldable IOL into the capsular bag combined with posterior capsulotomy was the preferred surgical treatment of choice for congenital/developmental cataracts.

    ABSTRACT: To measure retinal nerve fiber layer thickness (RNFLT) and ganglion cell complex thickness (GCCT) in eyes with no light perception due to nonglaucomatous optic neuropathy using spectral-domain optical coherence tomography. Fourteen eyes of 14 patients (9 women, 5 men; mean age 56.0 ± 16.6 (standard deviation) years] with no light perception due to optic neuropathy were recruited to this retrospective study. Only clinically stable eyes were included. Eyes were imaged at least 6 months after the onset of the disease. Five patients lost light perception due to traumatic optic neuropathy, four patients had ischemic optic neuropathy, two patients had optic neuritis, two patients had compressive optic neuropathy, and one patient had optic nerve atrophy. Global and quadrant RNFLTs were measured with the Cirrus HD-optical coherence tomography (OCT) system; global and hemisphere GCCTs were measured by spectral-domain OCT (RTVue OCT system). Only reliable OCT images were used for further analysis. Reliable RNFL images were obtained in 12 eyes, and reliable GCC images were obtained in 11 eyes. Global, superior, temporal, inferior, and nasal RNFLT were 57.5 ± 6.7, 60.6 ± 7.6, 54.1 ± 11.2, 59.7 ± 9.5, and 55.6 ± 7.4 µm, respectively. Global, superior, and inferior GCC thicknesses were 68.8 ± 9.6, 70.7 ± 12.2, and 67.8 ± 8.8 µm, respectively. A considerable proportion of RNFL and GCC remained in eyes with no light perception vision. Clinicians should take this into account when evaluating the severity of optic neuropathy from OCT-measured RNFLT and GCCT.

    ABSTRACT: To investigate macular morphology on spectral-domain optical coherence tomography (SD-OCT) images after microincision vitrectomy for vitreous hemorrhage associated with proliferative diabetic retinopathy (PDR). In this retrospective case series, 69 eyes (57 consecutive patients) that underwent 23-gauge microincision vitrectomy for vitreous hemorrhage due to PDR were investigated. Qualitative and quantitative characteristics on SD-OCT images [central retinal thickness, external limiting membrane (ELM), and the ellipsoid zone, epiretinal membranes involving the fovea, and hyperreflective foci at the fovea] were assessed 6 months postoperatively. Their association with the logarithm of the minimum angle of resolution visual acuity (logMAR VA) was evaluated. The ELM was disrupted in 15 and the ellipsoid zone in 27 eyes, and associated significantly (P < 0.001, for both comparisons) with poor visual outcomes 6 months postoperatively. Hyperreflective foci in the outer retinal layers were associated with either a disrupted ELM or ellipsoid zone and poor prognoses (P < 0.001, for all comparisons). The accumulation of hyperreflective foci at the fovea in five eyes was correlated significantly (P < 0.001) with poorer logMAR VA. Twenty-nine eyes had center-involved diabetic macular edema 6 months postoperatively, whereas the central thickness was not correlated with the logMAR VA (R = -0.148, P = 0.224). Eight eyes with either epiretinal membrane on SD-OCT images had greater central thickness (P = 0.003), although there were no differences in the logMAR VA between eyes with and without it (P = 0.648). Foveal photoreceptor damage is associated with poor visual outcomes after microincision vitrectomy for vitreous hemorrhage due to PDR.

    ABSTRACT: To study the indications for and effectiveness of Nunchaku-style silicone tube intubation (NSTI) in treating primary acquired lacrimal drainage obstruction (PALDO). In this interventional cohort study, 235 consecutive patients in 1 institution who had complete lacrimal obstruction were investigated. Of those, 212 PALDO patients were enrolled, and 156 of the PALDO patients ultimately satisfied our treatment protocol and were then followed up for 12 months postsurgery. Patients without dacryocystitis underwent NSTI, while those with dacryocystitis underwent NSTI or endonasal dacryocystorhinostomy (EN-DCR) using the NST as a stent. The tubes were left in place for 8 weeks, and all patients received identical postoperative care. Resolution was deemed as patency assessed by irrigation. Logistic regression analyses were performed to compare the success of NSTI for upper (puncta and canaliculus) and lower (lacrimal sac and nasolacrimal duct) obstruction, NSTI for lower obstruction with and without dacryocystitis, and NSTI and EN-DCR for lower obstruction with dacryocystitis. Comparison of the success rates at 12 months postsurgery showed significance as follows: treatment with NSTI was more successful for upper obstruction (94.6 %) than for lower obstruction (71.4 %) [odds ratio (OR) 8.23; P < 0.01]; treatment with NSTI was more successful for lower obstruction without dacryocystitis (82.9 %) than for dacryocystitis (52.4 %) (OR 4.96; P < 0.05); and treatment with EN-DCR (95.5 %) was more successful than NSTI (52.4 %) for treating lower obstruction with dacryocystitis (OR 16.99; P < 0.001). NSTI is effective for treating PALDO; however, EN-DCR is more effective for treating PALDO cases complicated by dacryocystitis.

    ABSTRACT: The pathogenesis of unilateral acute idiopathic maculopathy (UAIM) is unknown. The aim of this study was to quantitatively examine changes in choroidal circulation hemodynamics in patients with UAIM. This was a retrospective observational case-series which included five eyes of four patients with UAIM. All UAIM eyes and the fellow eyes in remaining three patients were studied using laser speckle flowgraphy (LSFG) to evaluate the mean blur rate (MBR), a quantitative index of relative blood flow velocity. The changes in MBR between the initial visit and after 1 and 3 months were statistically analyzed. Subfoveal choroidal thickness was measured in three UAIM eyes by enhanced depth imaging optical coherence tomography. The mean logMAR value of best-corrected visual acuity in the UAIM eyes significantly improved (P = 0.04) with recovery of outer retinal morphology. The average MBR of the UAIM eyes significantly increased at 1 (+21.7 % baseline value; P = 0.003) and 3 months (+32.5 % baseline value; P = 0.001), whereas the fellow eyes did not show this tendency. The mean values of subfoveal choroidal thickness decreased with time (316.0 µm at baseline, 186.6 µm at 1 month, and 167.3 µm at 3 months). These results reveal that there is a significant elevation of choroidal blood flow velocity and substantial reduction of choroidal thickness with regression of UAIM, suggesting that impaired choroidal circulation may be involved in the pathogenesis of UAIM.

    ABSTRACT: To investigate the influence of the optic disc type on the overall and regional correlation between structure and function in open angle glaucoma (OAG). We divided 144 eyes of 144 patients with OAG into four groups according to Nicolela et al.'s classification of optic disc type: focal ischemic (FI), myopic glaucomatous (MY), senile sclerotic (SS), and generalized enlargement (GE). We measured the circumpapillary retinal nerve fiber layer thickness (cpRNFLT) with the 3D OCT-2000 and the mean deviation (MD) with the Humphrey Field Analyzer in each group and determined the influence of the disc type on these parameters with the Spearman rank correlation. We found that cpRNFLT and MD were significantly correlated in the MY (r = 0.61, P < 0.001), GE (r = 0.62, P < 0.001), and SS groups (r = 0.52, P = 0.002), but not in the FI group (r = 0.25, P = 0.130). The region of the optic disc with the highest correlation coefficient between structure and function differed according to the disc type. The correlation between cpRNFLT and MD varied according to the optic disc morphology in OAG. This suggests that different disc types have characteristic regional variations in the correlation between structure and function. The disc type should therefore be considered in investigations of the correlation between structure and function in glaucoma.

    ABSTRACT: To investigate the safety and efficacy of intravitreal injection of melphalan for retinoblastoma. A retrospective chart review of all patients who were administered intravitreal injections of melphalan for retinoblastoma between 1990 and 2011. A total of 264 eyes of 250 patients were included. All ocular adverse events, systemic prognosis, ocular prognosis, and visual acuity were investigated. The total number of intravitreal injections administered was 1,067; each eye received between one and 25 injections. A postoperative subconjunctival tumor developed in one eye. None of the eyes suffered infections or uveitis, and all other adverse events including chorioretinal atrophy displayed incidences of less than 1.5 %. At 5 postoperative years, the cumulative incidence of cataract surgery was 3.1 % among the eyes that were treated without ocular hyperthermia. Distant metastasis or intracranial invasion occurred in 11 patients, all of whom had high-risk pathological factors for metastasis such as optic nerve invasion, but refused to receive adjuvant chemotherapy. Sixty-eight percent of the eyes achieved complete vitreous seed remission, but recurrence occurred in 19 % of these eyes after 10.0 ± 4.9 months. In addition, 47 and 27 % of the eyes without primary macular tumors retained visual acuity of >0.5 and >1.0, respectively. The risk of extraocular tumor spreading following intravitreal injections is low, and other adverse events are rare. Sixty-eight percent of the treated eyes achieved complete vitreous seed remission, and about half of them retained practical levels of vision. The intravitreal injection of melphalan is a safe and effective treatment for vitreous seeds.

    ABSTRACT: Our aim was to determine the recurrence rate of inflammation in Vogt-Koyanagi-Harada (VKH) disease and to describe its clinical features. We retrospectively evaluated patients diagnosed as having VKH disease with exudative retinal detachment at the Osaka University Hospital or the Japanese Community Healthcare Organization, Osaka Hospital, between 1998 and 2012. All patients received high-dose corticosteroid therapy as the initial treatment and were followed for at least 6 months. Demographic data, including age, sex, visual acuity (VA) levels at initial presentation and at 1 year after initial therapy, treatment received, and recurrent episodes were reviewed. Fifty-five consecutive patients with VKH disease were identified (36 women; mean age 38.6 ± 10.4 years). Fourteen patients (25.5 %) had recurrent inflammation, which manifested as posterior uveitis in eight and as anterior uveitis in six of the patients. Recurrent posterior segment inflammation was more likely to develop in patients whose VA at initial presentation was poor (P = 0.039) and in whom orally administered corticosteroid was tapered rapidly (to 30 mg within 3 weeks or less, to 20 mg within 2 months or less, and to 10 mg within 3 months or less) (P = 0.006, P = 0.066, and P = 0.041, respectively). About 25 % of patients with VKH disease had recurrent inflammation. Poor initial VA and rapid tapering of the corticosteroid were associated with posterior recurrence.

    ABSTRACT: To analyze the relationship between changes in the intraocular pressure (IOP) and dislocation angle in highly myopic strabismus patients who had undergone muscle union surgery. Medical data were examined of eight eyes of seven consecutive patients with highly myopic strabismus, who had some limitation in abduction, received muscle union surgery and undergone pre- and postoperative IOP evaluation with a noncontact tonometer, and were retrospectively reviewed. In addition, 15 eyes of 15 patients with comitant horizontal strabismus who underwent unilateral recess-resect procedure as well as pre- and postoperative IOP evaluation were also included. The correlation between IOP changes after strabismus surgery and the dislocation angle of the globe was analyzed. The IOP was significantly reduced in the highly myopic strabismus group (-5.6 mmHg) but not in the fellow eye or in comitant horizontal strabismus patients. The decrease in IOP after surgery was significantly correlated with the preoperative dislocation angle of the globe (r = -0.725, p = 0.042). IOP is often higher in highly myopic strabismus patients than perceived, and it may indicate abnormal anatomy of the orbit rather than glaucoma. In that case, muscle union surgery can improve eye position and normalizes the IOP.

    ABSTRACT: The purposes of this study are to develop and validate new diagnostic criteria for acute retinal necrosis (ARN) based on the ocular findings, clinical course, and virologic testing of intraocular fluids. The Japanese ARN Study Group, comprising 8 uveitis specialists and 1 statistician, was formed to develop new diagnostic criteria for ARN. The criteria used a combination of clinical features consistent with ARN including 6 early-stage ocular findings ([1a] anterior chamber cells or mutton-fat keratic precipitates; [1b] yellow-white lesion(s) in the peripheral retina [granular or patchy in the early stage, then gradually merging]; [1c] retinal arteritis; [1d] hyperemia of the optic disc; [1e] inflammatory vitreous opacities; and [1f] elevated intraocular pressure), 5 clinical courses ([2a] rapid expansion of the retinal lesion(s) circumferentially, [2b] development of retinal breaks or retinal detachment, [2c] retinal vascular occlusion, [2d] optic atrophy, and [2e] response to antiviral agents), and the results of virologic testing of intraocular fluids by means of either polymerase chain reaction or the Goldmann-Witmer coefficient for herpes simplex virus or varicella zoster virus. Various combinations of findings were analyzed to maximize the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The criteria were then used to retrospectively analyze patients who had been diagnosed as having ARN or control uveitis. Patients were followed at 1 of 7 tertiary uveitis clinics between 2009 and 2011. Analysis of the data allowed delineation of 2 levels of diagnosis: "virus-confirmed ARN" (defined as the presence of both early-stage ocular findings 1a and 1b, the presence of any 1 of the 5 clinical courses, and a positive virologic test result) and "virus-unconfirmed ARN" (defined as the presence of 4 of 6 early-stage ocular findings including 1a and 1b, presence of any 2 of the 5 clinical courses, and a negative virologic test result, or when virologic testing had not been performed). The new diagnostic criteria were applied to 45 patients with ARN and 409 patients with control uveitis, resulting in a sensitivity of 0.89, a specificity of 1.00, a PPV of 1.00, and an NPV of 0.99. New diagnostic criteria for ARN were developed and found to achieve high statistical values.
