Visual Function of Cynomolgus Monkeys with Bilateral or Unilateral Ocular Abnormalities

Abstract

We examined forty-seven cynomolgus monkeys with normal ophthalmoscopic findings, seventeen monkeys with bilateral ocular abnormalities, and eight monkeys with unilateral ocular abnormalities for their visual function, using the simplified method for judging visual function of the cynomolgus monkey, which was established previously (Suzuki et al., 1988). The monkeys with bilateral ocular abnormalities were inferior in their visual function to the monkeys with normal fundus. The monkeys with unilateral ocular abnormalities showed about the same degree in their visual function as the monkeys with normal fundus.
