Abstract

A long term study of argon laser inflicted retinal lesions in rhesus monkeys was carried out. Clinical and histologic findings showed evidence of recovery of the retinal pigment epithelium (RPE) and photoreceptor cells from the initial acute insult. Lesions produced by low doses of argon laser radiation (13 to 21 mw) appeared to recover completely, except for irregular pigmentation of the RPE. Lesions inflicted by large doses of radiation (47 to 75 mw) showed recovery of photoreceptor cells in the peripheral areas, where the nuclei and inner segments remained intact. Rod cells predominated in the peripheral zone of recovery.
