PURPOSE: To investigate the autofluorescence characteristics in patients with central serous chorioretinopathy. DESIGN: Observational case series. PARTICIPANTS: Thirty consecutive patients examined in a private referral practice. METHODS: Patients were imaged with autofluorescence photography, fundus photography, fluorescein angiography, and optical coherence tomography (OCT). The mean and standard deviation (SD) of the grayscale values from a 100-pixel-diameter circle centered on the fovea were obtained and normalized with the level of autofluorescence of the posterior pole. RESULTS: There were 30 patients, 23 male (76.7%) and 7 female (23.3%), with a median visual acuity (VA) of 20/25 and a range of 20/15 to 20/400. Stepwise linear regression that included individual fixed effects found that normalized central macular autofluorescence (P < 0.001), pigment mottling in the fovea (P = 0.045), subfoveal fluid detected by OCT (P = 0.033), and the SD of the central macular autofluorescence (P = 0.025) produced a highly significant model (R2 = 0.92, P < < 0.001) predicting VA. Increasing levels of autofluorescence were correlated with accumulation of material on the outer surface of the retina as seen by OCT. Decreased central macular autofluorescence, particularly in those eyes with central geographic retinal pigment epithelial atrophy, was associated with poor VA. CONCLUSIONS: This study established that autofluorescence changes occurring in central serous chorioretinopathy with explicit patterns can be measured in a noninvasive manner, and this information can be used to estimate the damage induced by central serous chorioretinopathy with a high degree of statistical significance. We hypothesize that the material on the outer surface of the elevated retina may represent accumulation of photoreceptor outer segments secondary to the lack of direct apposition and phagocytosis by the retinal pigment epithelium

PURPOSE: To report a case of bilateral diffuse uveal melanocytic proliferation (BDUMP) that had areas of retinal pigment epithelial loss. DESIGN: Observational case report. METHODS: A 67-year-old woman with a history of uterine cancer presented with 4 months of bilateral visual loss. RESULTS: Although B-scan ultrasonography revealed both small shallow serous retinal and choroidal detachments in the periphery, the choroid was normal in thickness. Fluorescein angiography revealed numerous nummular-shaped areas of transmission defects suggesting retinal pigment epithelium loss. Autofluorescence photography showed complete absence of autofluorescence in these nummular areas, and optical coherence tomography showed segmental areas with lack of any signal from affected areas of the retinal pigment epithelium, suggesting complete loss of retinal pigment epithelium cells. CONCLUSIONS: Although the fundus findings in BDUMP have been attributed to the proliferation of uveal melanocytic cells in the outer choroid in previous papers, our patient had nummular areas of loss of the retinal pigment epithelium as the apparent reason for visual decline

PURPOSE: To report the use of photodynamic therapy with verteporfin as a treatment for patients with focal retinal pigment epithelial leaks secondary to central serous chorioretinopathy (CSC). DESIGN: Noncomparative, nonrandomized, retrospective interventional case series. PARTICIPANTS: Nine eyes of 9 symptomatic patients with acute focal retinal pigment epithelial leaks secondary to CSC, confirmed with fluorescein angiography, evaluated at 1 of 3 referral retina practices. METHODS: Patients were treated with photodynamic therapy using verteporfin. Best-corrected visual acuity (VA) was recorded at presentation and follow-up visits. MAIN OUTCOME MEASURES: Resolution of neurosensory detachment, status of fluorescein leakage, and VA. RESULTS: Neurosensory detachment and fluorescein leakage resolved in all patients within 1 month. Visual acuity improved from 1 to 6 lines in 7 eyes and remained unchanged in 2. At 6 months, there was a statistically significant improvement in mean VA (P = 0.012, Wilcoxon signed ranks test), and mean VA improved from 20/80 to 20/40. No patient lost vision or suffered any treatment-related complications. CONCLUSION: The treatment of acute CSC with photodynamic therapy may result in prompt resolution of neurosensory detachment and fluorescein leakage, which can be associated with rapidly improved vision. Although this case series is limited in follow-up and number of patients, the encouraging results and lack of visually significant complications suggest that further investigation is warranted

PURPOSE: To investigate the manifestations and clinical course of Coats' disease diagnosed in adulthood and to describe the characteristics of patients who develop it. DESIGN: Retrospective observational case series. PARTICIPANTS: Thirteen eyes of 13 patients with Coats' disease diagnosed after age 35 years. METHODS: All patients examined in the authors' referral practices for Coats' disease diagnosed after the age of 35 years were identified. Patients with a history of radiation exposure, intraocular inflammation, retinal vascular occlusion, or Coats' response were excluded. A review of their historical, clinical, and fluorescein angiographic features and demographics was performed. RESULTS: There were 13 patients with a mean age at diagnosis of 50 years (range, 36-79) and a mean follow-up of 5.8 years (range, 0-17). These patients manifested many findings typical of Coats' disease, including the unilateral nature of the disease (13/13 patients), male predominance (12/13), vascular telangiectasis, lipid exudation, macular edema, and areas of capillary nonperfusion with adjacent webs of filigreelike capillaries. Disease was limited to < or =6 clock hours in 10 of 13 patients (76.9%), did not generally involve the retinal vasculature anterior to the equator, and showed limited potential to expand during the follow-up period. A localized hemorrhage was noted in 10 of 13 patients (76.9%), almost always near larger aneurysmal dilatations. Limited exudative detachment of the retina was seen in 4 eyes, 3 of which responded to localized laser photocoagulation. One patient had subretinal fluid seen on ocular coherence tomography that did not require treatment. On average, patients lost 2.1 lines of visual acuity during the follow-up period; 6 patients had a decline in vision, 2 patients had improved vision, and 3 patients had stable vision. No patient had end-stage findings of Coats' disease, such as iris neovascularization or total exudative detachment. CONCLUSIONS: Coats' disease can first be diagnosed in adulthood with retinal vascular abnormalities similar to those seen in younger patients. There are a number of important differences in disease manifestation in adults, including limited area of involvement, slower apparent progression of disease, and hemorrhage near larger vascular dilatations
