Objective To study the visual and angiographic outcome of eyes with neovascular age-related macular degeneration associated with pigment epithelium detachment (PED) treated by photodynamic therapy.
Methods Review of the medical charts and the fluorescein and indocyanine green angiograms of all consecutive patients with age-related macular degeneration associated with choroidal neovascularization and serous PED of at least 1 disc diameter, who received photodynamic therapy from January 1, 2000, to August 31, 2002.
Results Thirty patients (34 eyes) met the study criteria. Each underwent 1 to 8 treatments (mean, 4); duration of follow-up was 12 to 36 months (mean, 19 months). Nineteen eyes (56%) lost 3 or more Snellen lines of visual acuity, 7 eyes (21%) lost 1 or 2 lines, 6 eyes (18%) maintained their initial acuity, and 2 eyes (6%) gained 1 or 2 lines. Subretinal hemorrhage occurred in 5 eyes and retinal pigment epithelium tears in 4 eyes. In 4 eyes, visual acuity decreased to counting fingers, hand motions, or light perception.
Conclusions Although 44% of the 34 eyes with age-related macular degeneration and PED lost fewer than 3 Snellen lines in acuity, severe visual loss to counting fingers or less occurred in 4 eyes, 3 of them with choroidal neovascularization inside the PED. Further studies and treatment modalities are required to improve prognosis of neovascular age-related macular degeneration with serous PED.
