Age-related macular degeneration (AMD) is a chronic, progressive, degenerative disease of the macula and is the leading cause of central vision loss among elderly people in the western world. Traditionally, clinical studies of AMD have described the impact of AMD, and treatments for AMD, in terms of the patient's visual acuity. However, visual acuity alone does not provide information about a patient's perception of his or her quality of life. Researchers have used a variety of instruments to measure quality of life. Several studies have shown that AMD can severely impair quality of life and that increasing vision loss is associated with increasing impairment of quality of life and frequently causes depression. Interestingly, patients with only one eye affected may become more depressed than those with both eyes affected, possibly because of uncertainty surrounding future vision loss in patients with one eye affected and a greater acceptance of the condition in those with both eyes affected. Studies also have provided some information on the possible quality of life benefits of therapy for AMD. By incorporating measurements of quality of life into the design of future prospective studies, clinical researchers may be able to obtain more comprehensive data on the impact of AMD on patients and the relative benefits of different therapies

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

OBJECTIVE: To compare the treatment effect and safety of photodynamic therapy with verteporfin using a standard (SF) or reduced (RF) light fluence rate with that of placebo therapy in patients with subfoveal minimally classic choroidal neovascularization (CNV) with age-related macular degeneration. DESIGN: Phase 2, multicenter, double-masked, placebo-controlled, randomized clinical trial. SETTING: Nineteen ophthalmology practices in North America and Europe. PARTICIPANTS: Patients with initial best-corrected visual acuity of at least 20/250 and a lesion size of no greater than 6 Macular Photocoagulation Study (MPS) disc areas. METHODS: We randomly assigned 117 patients (1:1:1) to verteporfin infusion (6 mg/m(2)) and light application with an RF rate (300 mW/cm(2)) for 83 seconds (light dose of 25 J/cm(2)) or an SF rate (600 mW/cm(2)) for 83 seconds (light dose of 50 J/cm(2)) or to placebo infusion with RF or SF. Treatment was repeated every 3 months if the treating physician noted fluorescein leakage from CNV on angiography. Patients in whom a predominantly classic lesion developed could receive open-label standard verteporfin treatment. Best-corrected visual acuity was measured every 3 months, and angiographic changes were assessed by the Photograph Reading Center through the 3-month examination unless an ocular adverse event or conversion to a predominantly classic lesion was identified by an investigator. Safety was assessed throughout the study. All outcomes were on an intent-to-treat basis. RESULTS: One hundred three (88%) of 117 patients completed the 24-month examination. Twelve (30%) of 40 patients assigned to placebo received open-label standard verteporfin treatment after confirmation of presence of predominantly classic CNV. At month 12, a loss of at least 3 lines of visual acuity occurred in 5 (14%) of 36 eyes assigned to RF and 10 (28%) of 36 eyes assigned to SF, compared with 18 (47%) of 38 eyes assigned to placebo (RF, P = .002; SF, P = .08; RF + SF, P = .004). At month 24, this loss occurred in 9 (26%) of 34 eyes assigned to RF and 17 (53%) of 32 assigned to SF, compared with 23 (62%) of 37 eyes assigned to placebo (RF, P = .003; SF, P = .45; RF + SF, P = .03). Progression to predominantly classic CNV by 24 months was more common in the placebo group (11 [28%] of 39 patients compared with 2 [5%] of 38 in the RF group [P = .007] and 1 [3%] of 37 in the SF group [P = .002]). No unexpected ocular or systemic adverse events were identified. Treatment-related, usually transient visual disturbances were 13% with SF, 10% with placebo, and 5% with RF. CONCLUSIONS: Verteporfin therapy safely reduced the risks of losing at least 15 letters (> or =3 lines) of visual acuity and progression to predominantly classic CNV for at least 2 years in individuals with subfoveal minimally classic lesions due to age-related macular degeneration measuring 6 MPS disc areas or less. Based on the overall evidence available on verteporfin therapy for these lesions, the VIM Study Group would consider recommending verteporfin therapy for relatively small minimally classic lesions similar to those enrolled in the VIM Trial
