[Dye lasers: experimental histopathologic study of the effects of various wavelengths on the macular region].

Pathological experimental study of dye laser photocoagulation simulating the confluent treatment of subretinal new vessels in the macular area of a Macacas Cynomolgus monkey. 38 days after treatment the lesions become similar on the choriocapillaris and retinal pigment epithelium whatever the wavelength; the choriocapillaris is always occluded and the pigment epithelium destroyed. The internal limiting membrane is ondulated only with yellow and orange colors. These results are compared to those of similar experimental studies.
