Transpupillary thermotherapy: effect of wavelength on normal primate retina.

Purpose:To correlate changes in primate fundus after transpupillary thermotherapy (TTT) at two wavelengths.Methods:Twelve primate eyes were treated with TTT using a wavelength of 635 nm (n = 7) or 810 nm (n = 5). Laser parameters were as follows: 635 nm (spot size, 1 mm; duration, 30–80 seconds; and
