Effects of brief periods of unrestricted vision on the development of form-deprivation myopia in monkeys.

To characterize the temporal integration properties of the mechanisms responsible for form-deprivation myopia (FDM), the effects of brief daily periods of unrestricted vision on the degree of FDM were investigated in infant monkeys.Starting at approximately 3 weeks of age, unilateral form deprivation was produced in 24 infant rhesus monkeys by securing a diffuser spectacle lens in front of one eye and a clear, zero-powered lens in front of the...
