A LONGITUDINAL ANALYSIS OF THE REFRACTIVE CHARACTERISTICS OF CHIMPANZEES.
Abstract
Sixty chimpanzees, 34 males and 26 females ranging in age from less than 3 years to 10 years old, were refracted in the supine position under sernyl (proprietary preparation of Park-Davis and Company) anesthesia and cyclogyl cycloplegia. Intraocular pressures were obtained under the same conditions. The tendency toward increasing minus refractive error as a function of age was confirmed, and a statistically significantly lower intraocular tension in the males was found. Intraocular tension increased statistically significantly in the 24 month test-retest design. It was concluded that sernyl anesthesia yields no contraindictions for the continued use of this anethetic for the evaluation of the refractive status of the chimpanzee. (Author)
