    ABSTRACT: The purpose of this case series is to describe if the intravitreal use of bevacizumab and perfluoropropane gas (C3F8) would be beneficial to the displacement of subretinal hemorrhage in patients with age-related macular degeneration (AMD). A retrospective study of 5 eyes that received concurrent intravitreal injection of bevacizumab and C3F8 was performed. The results were graded according to blood displacement under the fovea, best final visual acuity and intraoperative complications. At the initial presentation, mean age of patients was 72.6 +/- 8.9 years-old and duration of symptoms was 13 +/- 9.7 days. From the 5 patients, 3 (60%) were male and 2 (40%) female. The success of submacular hemorrhage full displacement was achieved in 4 patients. The mean preoperative visual acuity (VA) was 1.12 +/- 0.34 logMAR and the mean postoperative VA was 0.92 +/- 0.4 logMAR. No cases of retinal detachment, endophthalmitis, vitreous hemorrhage, uveitis, cataracts and increased intraocular pressure were noted during the follow-up period. Intravitreal bevacizumab and C3F8 injection, associated to prone position can be a valuable therapeutic option for eyes with neovascular age-related macular degeneration and subretinal hemorrhage to the blood displacement out of the foveal area.

    ABSTRACT: To investigate whether the time interval between type 2 diabetes mellitus (DM) diagnosis and the first fundoscopic examination is related with the presence and the severity of diabetic retinopathy (DR) observed. A survey of 105 type 2 DM patients referred to ophthalmologic evaluation in the "Hospital das Clinicas" (HC), University of São Paulo Medical School (USPMS). Regarding classification of DR in the 105 patients, 15 (14.28%) did not show signs of DR, and 90 (85.72%) exhibited them on fundoscopy. Sixty patients underwent laser therapy, and 46.66% reported poor control of DM. Only 15.23% of DM patients were adequately screened for DR on the first year of their DM diagnosis. Among the 36 patients (34.30%) examined within five years of DM diagnosis, 58.33% did not present or demonstrate signs of mild DR and 22.20% of proliferative DR; 30 patients underwent an ophthalmologic examination after more than eleven years of DM diagnosis, 21.62% did not exhibit signs of DR and 59.46% were classified as proliferative DR. This study showed a statistically significant relationship between the time interval from the diagnosis of type 2 DM and the first fundoscopic examination with the severity of DR.

    ABSTRACT: The aim of this study was to verify the influence of prostaglandin analogs and prostamide on central corneal thickness (CCT). A prospective analysis was done of CCT in glautomatous patients submitted to monotherapy with prostaglandin analogs (latanoprost 0.005% or travoprost 0.004%) or prostamide (bimatoprost 0.03%) during an 8-week period. A control group of patients without any ocular medication was also evaluated. CCT measurements were performed with a commercially available ultrasound pachymeter. A total of 73 patients were included in this study. Mean age was 68.5 +/- 9.2 (range, 48-85) years old. A statistically significant reduction in CCT was observed in all groups, except the control group (n = 21): Bimatoprost 0.03% group (n = 21): 544.41 +/- 35.4 vs. 540.35 +/- 35.9 microm (P = 0.039); travoprost 0.004% group (n = 17): 538.47 +/- 32.0 vs. 532.25 +/- 30.4 microm (P = 0.009); latanoprost 0.005% group (n = 14): 548.57 +/- 32.4 vs. 543.88 +/- 35.6 microm (P = 0.036). Topical therapy with prostaglandin analogs and bimatoprost is associated with CCT reduction over a period of at least 8 weeks.

    ABSTRACT: The purpose of this case report was to correlate optical coherence tomography findings and visual outcomes of patients with different degrees of commotio retinae. A 20-year-old male and a 23-year-old male that presented with decreased vision due to Berlin's edema after blunt ocular trauma were evaluated by optical coherence tomography and retinography. The visual acuity in the affected eye was 20/25 in the first patient and counting fingers in the second one. The ophthalmic examination showed traumatic uveitis and fundoscopy revealed mild retinal opacification in the first case and severe opacification in the latter. The optical coherence tomography confirmed the reduction of foveal depression on the first case and the disarrangement of all retinal layers on the second. There has been complete functional and anatomical resolution by optical coherence tomography in the first patient, while the second evolved to permanent visual loss. Optical coherence tomography is a useful method in the evaluation of retinal trauma, helping to understand its physiopathology and to predict its prognosis through the anatomical analysis of the affected region.

    ABSTRACT: Chloroquine diphosphate has been used in the treatment of various rheumatic diseases, including rheumatoid arthritis. The most important of its side effects is retinopathy. If not diagnosed early, this lesion can evolve into irreversible bull's eye maculopathy and visual loss. The aim of this study was to define the outcome of chloroquine-induced maculopathy after cessation of chloroquine therapy and also to identify the risk factors involved in case of retinopathy evolution. The design of this cohort study was longitudinal and retrospective. Over the period spanning 2000 to 2005, out of 607 medical records of patients with rheumatoid arthritis followed in our Division of Rheumatology, 27 had been diagnosed with chloroquine-induced maculopathy through clinical funduscopy with pupil dilation. In all cases, there was immediate chloroquine intake cessation. After a mean time of 5 years, 16 of these patients were available for follow-up and underwent a new ophthalmologic evaluation by funduscopy, using biomicroscopy and angiofluorescein when necessary. Sequelae maculopathy were reconfirmed in all 16 cases, but progression to advanced stage (bull's eye maculopathy) was found in half of the cohort, even though chloroquine had been suspended. All patients complained of visual alterations, but without progression. Comparison between patient groups with and without bull's eye maculopathy revealed a statistically significant longer rheumatoid arthritis disease history in the former group. Also, the bull's eye group had higher dose intakes of chloroquine and over a longer period compared to the other group, but not statistically significant. This study corroborates the progression of maculopathy even after cessation of chloroquine intake, pointing out the need for careful screening in the high-risk patients. Furthermore, it indicates that duration of rheumatoid arthritis disease could be a possible factor linked to worse prognosis of chloroquine-induced maculopathy.

    ABSTRACT: To determine whether there is a correlation between asymmetric glaucomatous visual field (VF) damage and water-drinking test (WDT) response. A retrospective analysis was conducted of VF and WDT data from 101 patients with glaucoma in clinical therapy, who were receiving treatment with the same topical medication in both eyes, and asymmetric VF defect. Eyes were classified according to mean deviation (MD) into "better" and contralateral "worse" eyes. Maximum mean difference in basal IOP was 2 mm Hg between both eyes. The peak IOP and fluctuation obtained with the WDT were compared between both groups. For the statistical analysis, the Tukey post hoc multiple comparison test and paired t-test were used. Better and contralateral worse eyes presented mean MDs of -4.6 +/- 5.3 and -9.0 +/- 7.4 dB, respectively (P < 0.001). Mean basal IOPs were 13.9 +/- 3.3 and 13.9 +/- 3.1 mm Hg, respectively (P = 0.67). Mean maximum IOPs after water ingestion were 16.5 +/- 3.8 mm Hg in the group with less severe VF defect and 17.2 +/- 4.1 mm Hg in the contralateral group with worse visual fields (P < 0.001). Mean fluctuation (maximum IOP - minimum IOP after water ingestion) was 3.6 +/- 1.8 and 4.4 +/- 2.2 mm Hg (P < 0.001), respectively. Eyes with worse MDs presented higher IOP peaks and fluctuation after water ingestion. This study demonstrates a lower capacity of eyes with worse glaucomatous lesion to respond to a stimulus that leads to a transitory elevation of IOP.

    ABSTRACT: Retinal vasoproliferative tumor is a rare and benign disease that presents with an exsudative lesion in the retinal periphery. The lesion can be classified as primary (idiopathic) or secondary to a number of previous retinal injuries. Diagnosis is based on a careful ophthalmic examination. Therapeutic options include observation, cryotherapy, laser photocoagulation and brachytherapy. We present a case of idiopathic retinal vasoproliferative tumor associated with macular edema. The aspects of the tumor on fundus examination, fluorescent angiography, echography and optic coherence tomography are discussed.
