Nonhuman primate restraint device for ocular drug studies

A restraining device for nonhuman primates was designed which effectively prevented the animal from touching the eyes and thereby transferring a topically applied drug from 1 eye to the other. This permitted use of 1 eye of the same animal as a reliable control for observation of pharmacologic effects. The design permitted self-feeding by the animal. It did not produce chafing or pressure sores and resulted in no psychologic depression. The device has been used successfully for a 5-mo period.
