    ABSTRACT: To assess macular choroidal thickness (CT) and axial length measurements in children with anisometropic amblyopia and to compare the measurements with that of fellow non-amblyopic eyes and age-sex matched controls. Forty patients with anisometropic amblyopia and 40 age-/sex-matched controls were evaluated in this study. Eyes were classified into three groups as follows: amblyopic eyes (n = 40), fellow non-amblyopic eyes, and healthy eyes (n = 40). All subjects underwent complete ophthalmic examination and macular choroidal thickness measurements by enhanced depth imaging method of the Spectralis optical coherence tomography system. CT was measured at the fovea and at 1000-μm intervals from the foveal center in both temporal and nasal directions. The statistical assessment was performed with the assistance of one-way analysis of variance (ANOVA) and Pearson's correlation test. The mean subfoveal CT was 389.35, 349.07, and 315.8 μm in the amblyopic, fellow non-amblyopic and healthy eyes, respectively. Choroid was thickest in subfoveal and thinnest in nasal regions among all groups. Both amblyopic and fellow non-amblopic eyes were more hyperopic than healthy eyes. While the subfoveal and nasal CT in amblyopic eyes and fellow eyes were significantly higher than healthy eyes, the temporal CT in amblyopic eyes was significantly higher than in healthy eyes. There was a significant positive correlation between the CT of the subfoveal, nasal, and temporal regions and the refractive state (r = 0.432 p = 0.001; r = 0.324 p = 0.001; r = 0.215 p = 0.01, respectively). The macular choroidal thickness-not only in amblyopic eyes but also in non-amblyopic fellow eyes-was significantly thicker than in the healthy subjects. The thick choroid in amblyopic and non-amblyopic fellow eyes may indicate bilateral delay of emmetropization, which probably means amblyopia affecting the visual feedback of both eyes.

    ABSTRACT: To study the potential effects of both prematurity and the sub-groups of low birth weight on thickness of RNFL. Prospective case series of 26 preterm school-aged children with low birth weight whose retinal nerve fiber layer analyses with RTVue-100 Fourier-domain optic coherence tomography were performed in 2013 at the Department of Ophthalmology, Erzurum Region Education and Training Hospital. The mean retinal nerve fiber layer thicknesses were 100.6 ± 13.3 microns in extremely low birth weight, 103.9 ± 8.4 microns in very low birth weight, and 104.1 ± 10.8 microns in low birth weight groups. There was no significant difference in RNFL among the groups. No significant relationship was found between birth weights and retinal nerve fiber layer thickness of preterm children who were appropriate for gestational age.

    ABSTRACT: To investigate the effect of chronic cigarette smoking on the endothelial cells of the cornea via non-contact specular microscopy. In this prospective, cross-sectional study, 25 eyes of 25 chronic smokers and 21 eyes of 21 age-matched, healthy non-smokers were enrolled. The Fagerström Test for Nicotine Dependence on Cigarettes was used to determine the nicotine dependency level. The level of cotinine, a major metabolite of nicotine, was measured in urine samples from the control group to detect whether they were passively affected by cigarette smoke. All participants underwent measurement of tear break-up time (TBUT), central corneal thickness (CCT), and axial length. Endothelial cell density and endothelial cell morphology were evaluated by non-contact specular microscopy. On average, the cigarette smokers consumed 19.2 ± 8.3 cigarettes per day and had been smoking for 14.5 ± 6.8 years. The mean TBUT value was significantly lower in the smoker group compared to the non-smoker group (p < 0.05). No statistically significant difference was found in the mean CCT, mean endothelial cell density, or parameters of endothelial cell morphology between smokers and non-smokers. This study showed that cigarette smoking seems to affect the TBUT value but no effects were found on the parameters of corneal endothelial cells.

    ABSTRACT: Ophthalmic involvement may lead to permanent vision loss in 25% of cases in patients with BD and it is a main concern in the literature. Although several studies have been investigated, the etiology and the cause of the disease and attacks are not yet known. This study aimed to investigate the correlation between visual impairment and personal characteristics and social circumstances in patients with BD. A total of 153 patients with BD and age-and gender-matched 26 healthy control subjects completed the self-report Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI), and State and Trait Anxiety Inventory (STAI-S and STAI-T). We classified the study participants into three groups with respect to severity of eye involvement and one control group. Each group was compared with the other two study groups and control group. According to TCI, we revealed that there was a trend in BD patients with eye involvement + poor prognosis having less disorderliness traits than BD patients with eye involvement + good prognosis (p = 0.016). The BD patients with eye involvement + poor prognosis had significantly lower attachment scores than BD patients with eye involvement + good prognosis (p = 0.005) and healthy controls (p = 0.005). The BD with eye involvement + poor prognosis had lower empathy scores than healthy controls (p = 0.002). In the way of average TCI parameters, only SD was statistically significant. In terms of subdimensions of TCI parameters, RD3, SD3, SD5, and C2 were shown to be statistically significant among some of the groups. BD patients with eye involvement were demonstrated to be more extravagant and socially disinterested. It may reflect that severe visual loss caused BD patients to be more systematic, depressive, self-contained, and exhausted. Considering psychological aspects of BD and its visual manifestations may contribute to helping these patients more effectively.

    ABSTRACT: To review the old and existing classification systems for primary angle closure disease. Literature review and new proposed classification system. Existing classification systems have several shortcomings which cannot be applied in a clinical setting. This can be addressed by a proposed scoring system. A scoring system would be most appropriate for any clinical setting as well as for prognosticating primary angle closure disease.

    ABSTRACT: To compare the outcomes of cataract surgery performed with three different types of the epinucleus removal techniques (safe boat, infusion/aspiration (I/A) cannulas, and phacoemulsification tip). Ninety eyes with thick adhesive epinuclei were randomly subdivided into three groups according to epinucleus removal technique: epinucleus floating (safe boat) technique, 30 patients; I/A tip, 30 patients; and phaco tip, 30 patients. Intraoperative measurements included ultrasound time (UST), mean cumulative dissipated ultrasound energy (CDE), and balanced salt solution (BSS) use. Clinical measurements were made preoperatively, and at one day, one month and two months postoperatively, including the best corrected visual acuity (BCVA), the central corneal thickness (CCT), and the endothelial cell count (ECC). Intraoperative measurements showed significantly less UST, CDE, and BSS use in the safe boat group than in the phaco tip groups (p < 0.05). The percentage of endothelial cell loss in the safe boat group was significantly lower than that in the phaco tip groups at two months post-cataract surgery (p < 0.05). The safe boat technique is a safer and more effective epinucleus removal technique than phaco tip techniques in cases with thick epinucleus.

    ABSTRACT: To evaluate the ganglion cell complex (GCC) and retinal nerve fiber layer (RNFL) thickness in pigment dispersion syndrome (PDS) and pigmentary glaucoma (PG) with RTVue spectral domain optical coherence tomography (SD-OCT). A total of 102 subjects were enrolled: 29 with PDS, 18 with PG, and 55 normal subjects. Full ophthalmic examination including visual field analysis was performed. SD-OCT was used to analyze GCC superior, GCC inferior, and average RNFL thickness. To compare the discrimination capabilities, the areas under the receiver operating characteristic curves were assessed. Superior GCC, inferior GCC, and RNFL thickness values of patients with PG were statistically signicantly lower than those of patients with PDS (p < 0.001) and healthy individuals (p < 0.001 for all). No statistically significant difference was found between PDS and normal subjects in same parameters (p > 0.05). The SD-OCT-derived GCC and RNFL thickness parameters can be useful to discriminate PG from both PDS and normal subjects.

    ABSTRACT: To review the management of keratitis after corneal bee stings and to report a case of deep stromal corneal infiltrate secondary to a retained bee stinger managed conservatively in a patient who presented three days after unsanitary manipulation of the stinger apparatus. Case report and review of literature. A 57-year-old male beekeeper was evaluated for pain, blurry vision, and photosensitivity after a corneal bee sting. Of note, the venom sac had been removed with dirty tweezers three days prior to his visit. On exam, a focal infiltrate with diffuse edema was seen surrounding a retained bee stinger in the peripheral cornea. Trace cells in the anterior chamber were also noted. Based on a high suspicion for infectious keratitis, a conservative treatment strategy was elected. Administration of broad-spectrum topical antibiotics with concomitant abstention of corticosteroids led to rapid resolution of the symptoms. Over 16 months of follow-up, the stinger has remained in situ without migration and the patient has maintained 20/20 visual acuity without complications. There is debate on the preferred method for the management of corneal injury secondary to bee stings, especially when it is associated with a retained stinger. We herein present our findings in our appraisal of reported cases. In the aftermath of an ocular bee sting, close surveillance for inflammation and infection is essential. Individual manifestations of these injuries vary in timing, type, and severity; therefore, the accessibility of the stinger and the evolving clinical picture should guide therapeutic decisions.

    ABSTRACT: To describe unilateral periarterial plaque in a case of bilateral acute retinal necrosis (BARN) due to varicella zoster virus (VZV). Case report. A 43-year-old diabetic male presented to us with dimness of vision in the left eye for three months. He was already on oral steroids and anti-viral therapy. Best-corrected visual acuity was 6/6 OD and hand movements close to face OS. The right eye showed inferior and temporal retinal thinning and pigmentation and periarterial whitish focal Kyrieleis' plaques, specifically along arterioles. Left eye had mild vitritis, optic disc pallor, arteriolar attenuation, with retinal whitening and areas of pigmentation involving 360° of peripheral retina along with some involvement of the posterior pole. Serology for human immunodeficiency virus (HIV), herpes simplex virus (HSV), and cytomegalo virus (CMV) was negative. IgM for VZV was positive. Oral Valacyclovir 1 g thrice daily was continued and a slow taper of oral steroids was instituted. ARN should be considered as a differential diagnosis in cases with Kyrieleis' plaques and a peripheral retinal examination must be done to rule out patches of healed retinitis and vasculitis.

    ABSTRACT: The iPad and iPhone have a number of low-vision accessibility features including Siri Voice Assistant, Large Text, Zoom Magnification, Invert Colors, Voice Over, and Speech Selection. We studied their usage within a low-vision population. Patients were recruited to participate in an IRB-approved survey regarding their usage of the iPad and/or iPhone. Participants met one of the following criteria: best corrected visual acuity (BCVA) of 20/60 or worse, or significant peripheral visual field defects. Thirty-three low-vision patients agreed to participate (mean age 54.3 years). There were 18 different diagnoses represented and the average visual acuity of respondents was 20/119 in the right eye and 20/133 in the left eye. The most commonly used vision accessibility features were Zoom Magnification and Large Text. Although many patients are using the low-vision accessibility features, few are receiving training or recommendations from their eye care specialist.

    ABSTRACT: Tube shunt implantation is a common procedure for control of intraocular pressure (IOP). However, tube revision and repositioning must sometimes be performed, and this involves removing the tube from its sclerostomy site. This site is prone to leaking and this may cause postoperative hypotony. We describe a novel and cosmetically acceptable technique of plugging and covering the sclerostomy site with gamma-irradiated corneal tissue.

    ABSTRACT: To assess diagnostic consistency and relation between spectral-domain optical coherence tomography (SD-OCT) and standard automated perimetry (SAP) in patients with primary open-angle glaucoma (POAG). This retrospective study comprised 51 eyes of 51 patients with a confirmed diagnosis of POAG. The qualitative and quantitative SD-OCT parameters (retinal nerve fiber layer thicknesses [RNFL; average, superior, inferior, nasal and temporal], RNFL symmetry, rim area, disc area, average and vertical cup/disc [C/D] ratio and cup volume) were compared with parameters of SAP (mean deviation, pattern standard deviation, visual field index, and glaucoma hemifield test reports). Fifty-one eyes of 51 patients with POAG were recruited. Twenty-nine eyes (56.9%) had consistent RNFL and visual field (VF) damage. However, nine patients (17.6%) showed isolated RNFL damage on SD-OCT and 13 patients (25.5%) had abnormal VF test with normal RNFL. In patients with VF defect, age, average C/D ratio, vertical C/D ratio, and cup volume were significantly higher and rim area was lower when compared to those of the patients with normal VF. In addition to these parameters, worsening in average, superior, inferior, and temporal RNFL thicknesses and RNFL symmetry was significantly associated with consistent SD-OCT and SAP outcomes. In routine practice, patients with POAG can be manifested with inconsistent reports between SD-OCT and SAP. An older age, higher C/D ratio, larger cup volume, and lower rim area on SD-OCT appears to be associated with detectable VF damage. Moreover, additional worsening in RNFL parameters might reinforce diagnostic consistency between SD-OCT and SAP.

    ABSTRACT: To report the incidence and progression of posterior vitreous detachment (PVD) and factors influencing the same in a cohort of patients with type 2 diabetes in a South Indian population. A subset of 615 subjects from Sankara Nethralaya Diabetic Retinopathy Epidemiology and Molecular Genetics Study II were included in this study. All of the subjects underwent detailed ophthalmic evaluation including stereo fundus photography. The status of PVD was assessed using B-scan ultrasonography. A p value of <0.05 was considered statistically significant. The incidence of either incomplete PVD (IPVD) or complete PVD (CPVD) from no PVD at baseline visit was 80.8%. Of them, 32.63% converted to CPVD from IPVD at baseline. High prevalence of emmetropia was observed in subjects with stable No PVD. Risk factors associated with the conversion of CPVD from no PVD and IPVD at baseline were age (OR: 1.04, p = 0.002), myopia (OR: 2.14, p = 0.009), and increase in axial length (OR: 1.35, p = 0.004). Subjects undergoing cataract surgery were at 2.32 times higher risk of converting to CPVD (p = 0.038). Independent risk factors for the progression of PVD were increase in age, myopia, increased axial length, and cataract surgery.

    ABSTRACT: During laparoscopic surgery, ocular complications are possible, sometimes leading to devastating visual losses, hardly susceptible to recovery, although rare. Principal ocular adverse events are represented by corneal abrasions and the perioperative visual loss (POVL). POVL onset is related to intraocular pressure elevations (particularly after patient positioning in Trendelenburg or prone decubitus, depending on the surgical procedure), anesthesiologic factors and patients' characteristics. In the light of evidence from the existing literature, the authors suggest surgical and anesthesiologic measures to prevent and manage ocular complications in laparoscopic surgery. Apart from general recommendations, this article indicates practical guidelines specific for robot-assisted laparoscopic interventions and spinal surgery, as well as laparoscopic colorectal resection, radical prostatectomy, and gynecologic surgery. In conclusion, in order to better manage these complications, it is advisable to develop an interdisciplinary collaboration between surgeons, anesthesiologists, and ophthalmologists, on a procedural and medico-legal level, with the intent of mutual training.

    ABSTRACT: To assess outcomes of visual acuity (VA) and central retinal thickness (RT) in patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO) who were initially treated with bevacizumab and followed for up to four years. In this observational case series, 51 patients with non-ischemic and ischemic CRVO who had initial treatment with bevacizumab were included. Main outcome measures were VA and RT at one year, with follow-up of up to four years. Mean VA improved from 20/214 at baseline to 20/107 at one year (p = 0.0009) and this improvement was maintained clinically at four years. RT decreased from 595 μm to 339 μm at one year (p = 0.0027) and this was maintained at four years. Patients who received bevacizumab as initial therapy for ME from CRVO maintained VA and RT improvement for up to four years.
