Visual Function in Cynomolgus Monkeys with Macula Degeneration

Abstract

A simple method for judging visual function in the cynomolgus monkey was designed. The principle of this method is to examine whether a monkey watches the eyes of two observers who wear a face hood with a sheet of neutral density filter paper attached. Thirty-four normal monkeys and eight monkeys with macula degeneration were examined by this method. The monkeys with macula degeneration were inferior in their visual function to the monkeys with normal fundus. In addition, the degree of visual function judged by this method was in accord with the degree of macula degeneration observed ophthalmoscopically.
