PURPOSE: To report combined treatment of photodynamic therapy (PDT) with verteporfin and intravitreal triamcinolone acetonide injection for subfoveal neovascularization secondary to bilateral idiopathic juxtafoveal telangiectasis. DESIGN: Interventional case report. METHOD: A patient with a subfoveal neovascularization secondary to bilateral idiopathic juxtafoveal telangiectasis was treated with PDT plus an intravitreal injection of 4 mg of triamcinolone acetonide. RESULTS: Leakage in the late-phase of fluorescein angiography resolved with attenuation of telangiectatic vessels and improvement in visual acuity from 20/200 to 20/50. At 9 months post-treatment, recurrent leakage was treated with repeat PDT and intravitreal triamcinolone. One year after initial presentation, visual acuity was 20/60 with no leakage on fluorescein. CONCLUSION: Combined treatment with PDT and intravitreal triamcinolone acetonide resulted in regression of a subfoveal neovascular membrane and improvement in visual acuity during the course of follow-up

PURPOSE: To evaluate the disease involvement in a patient with acute zonal occult outer retinopathy (AZOOR). DESIGN: Observational case report. METHODS: A patient with acute zonal occult outer retinopathy was imaged with fundus photography, fluorescein and indocyanine green angiography, and autofluorescence photography. RESULTS: There was subtle depigmentation in the central portion of the lesion with a drusen-like deposit at the outer border. Fluorescein angiography showed a transmission defect centrally and a blocking defect at the border where the drusenoid material accumulated. Autofluorescent photography demonstrated that the drusenoid material was intensely autofluorescent, consistent with the presence of lipofuscin, and the central portion of the lesion showed atrophy of the retinal pigment epithelium. Indocyanine green angiography showed atrophy of the choriocapillaris underlying areas of atrophy of the retinal pigment epithelium. CONCLUSIONS: In this case acute zonal occult outer retinopathy caused an area of retinal pigment epithelium cell death with lipofuscin-laden cells at the border of the expanding lesion and associated atrophy of the underlying choriocapillaris

PURPOSE: To report optical coherence tomography findings in nicotinic acid maculopathy. DESIGN: Observational case report. METHOD: The patient was examined with ophthalmoscopy, fluorescein angiography, and optical coherence tomography. RESULTS: A 71-year-old man presented with bilateral decreased visual acuity with metamorphopsia. Optical coherence tomography demonstrated cystoid spaces in the outer plexiform layer and inner nuclear layer. Fluorescein angiography did not show leakage. Two weeks after stopping the nicotinic acid, the cystoid spaces resolved. CONCLUSIONS: Niacin maculopathy causes cystoid spaces in the inner nuclear and outer plexiform layers that resolve with discontinuation of the drug

BACKGROUND: Most patients with central serous chorioretinopathy (CSC) have spontaneous resolution of exudative macular detachments and a good visual prognosis. Patients with CSC have a primary choroidal hyperpermeability problem evident as multifocal areas of hyperpermeability during indocyanine green (ICG) angiography. A small percentage of patients develop chronic or progressive disease with widespread decompensation of the retinal pigment epithelium and severe vision loss. There is no known treatment for this variant of the disorder. PURPOSE: To study ICG-guided photodynamic therapy (PDT) with verteporfin as a potential treatment for patients with chronic CSC. METHODS: Twenty eyes of 15 patients were studied with fluorescein angiography, optical coherence tomography, and ICG angiography to diagnose the maculopathy, monitor the detachments, and localize the choroidal hyperpermeability of the disorder. PDT with ICG guidance was applied to areas of choroidal hyperpermeability, and the patients were observed to determine the anatomic and functional outcomes. RESULTS: Photodynamic therapy guided by ICG was associated with complete resolution of exudative macular detachments in 12 patients and incomplete resolution in the remaining eight eyes. The vision improved in six eyes and remained unchanged in 14 eyes during a mean follow-up of 6.8 months. Six weeks after treatment, the mean visual acuity improved by 0.55 lines, an amount that was marginally significant. There was a significant inverse correlation between the baseline visual acuity and the amount of improvement in acuity at 6 weeks. No patient had any treatment-related side effects. CONCLUSIONS: Indocyanine green angiography-guided PDT with verteporfin seems to aid in the resolution of exudative detachments in patients with chronic CSC. This treatment was associated with a rapid reduction in subretinal fluid and improvement in visual acuity. Although the follow-up time and number of patients in this pilot study were limited, the encouraging results and lack of complications suggest that further study is indicated

PURPOSE: To evaluate the incidence of serous retinal detachment (SRD) secondary to a branch retinal vein occlusion (BRVO) by using optical coherence tomography (OCT). METHODS: Fourteen eyes of 14 patients with a BRVO underwent a detailed history, ophthalmoscopic examination, and fluorescein angiographic evaluation. They were also studied with OCT. RESULTS: The 14 patients included eight women and six men with a mean age of 73.6 +/- 10.5 years (range, 55-90 years). Four eyes were found to have cystoid macular edema by fluorescein angiography, whereas 10 cases were detected by OCT. SRD involving any portion of the macula was found in 10 (71.4%) of the 14 eyes, and SRD extending into the fovea was found in six (42.9%) eyes. Two (14.3%) of the 14 patients also showed a subfoveal hemorrhage that appeared to have gravitated inferiorly through the SRD to the dependent portion of the detachment. CONCLUSIONS: That few patients with SRD secondary to a BRVO discovered by ophthalmoscopy have been reported in the literature would suggest that this is an uncommon complication. The authors found with OCT that SRD commonly occurs in BRVO. In addition, subretinal hemorrhage may occur in the context of BRVO, and the authors propose that blood gravitates through the subretinal fluid to settle behind the retina
