Objective: To describe the outcome of patients with occult choroidal neovascularization in age-related macular degeneration treated with transpupillary thermotherapy. Design: Prospective, nonrandomized, nonmasked case series. Methods: All patients with age-related macular degeneration with a predominantly occult choroidal neovascular membrane and an initial visual acuity of 20/400 or better were offered treatment using transpu-pillary thermotherapy. The treatment consisted of using a diode laser, a spot size of about 3000 to 6000 μm delivered over 60 seconds, and a power of 600 to 1000 mW. Main Outcome Measures: A stable, improved, or worsened visual acuity and the need for additional treatment. Results: Sixty-nine patients were treated. All patients have been followed up for at least 6 months. At the 6-, 9-, and 12-month follow-up visits, 71% of patients have stable or improved visual acuity and 29% have lost 2 or more lines of visual acuity on the Snellen letter chart. Conclusion: Large-spot size transpupillary thermo-therapy is effective in stabilizing the visual acuity in those patients who have occult choroidal neovascularization due to age-related macular degeneration.
