Four Djungarian hamsters (Phodopus sungorus campbelli) were examined because of insidious globe enlargement, visual impairment and secondary altered behavior. Buphthalmos, deep anterior chambers, widely dilated pupils and poor to absent pupillary light reflexes were evident bilaterally in all four animals. Pale retinae and atrophic optic nerve heads were observed in the oldest hamsters. Light microscopic findings, including uveal atrophy, retinal atrophy (especially the inner retina), and a relative decrease in ganglion cells and optic nerve atrophy, were consistent with glaucoma. The etiology was unclear, but a genetic predisposition cannot be excluded.
