ABSTRACT
AIM:
To evaluate the efficacy of transpupillary thermotherapy (TTT) for treatment of subfoveal choroidal neovascularisation (CNV) secondary to age-related macular degeneration (AMD), and to define accurate power settings for this procedure in Indian eyes.METHODS:
A prospective, nonrandomised study of 160 eyes of 144 patients with subfoveal CNV. The laser settings included 2 mm spot and 300 mw power or 3 mm spot and 400-600 mw power. Two separate 3 mm spots were used in larger lesions. The treatment was given for 60 seconds at each point.RESULTS:
Ninety-nine eyes had classic membranes and 61 eyes had occult membranes. Following treatment, 79 of 99 (79.8%) classic and 52 of 61 (85%) occult membranes regressed. Visual improvement (> or = 2 lines) was seen in 29 (29.3%) eyes and 12 (19.6%) eyes; visual stabilisation (1 line) in 39 (39.4%) eyes, and 35 (57.4%) eyes; and reduction of vision (< or = 2 lines) in 31 (31.3%) eyes and 14 (22.9%) eyes with classic and occult membranes respectively. Mean follow-up was 12 months. One patient suffered inadvertant foveal burn.CONCLUSION:
TTT is effective in the management of subfoveal membranes in Indian eyes. They respond to lower energy levels compared to the Caucasian eyes.
