OBJECTIVE:To elucidate the nature of degenerations in canine peripheral retina and compare the degenerations with those in human peripheral retina. METHODS: Examining randomly the peripberal fundus of eighty eye balls of forty dogs wdh dissecting microscope. The lesions of degenerations were photographed and processed for light microscopic examination. RESULTS:Typical Cystoid degeneralion,reticular degenerative retinoschisis, paving-stone degeneration, and lattice degeneration were discovered. The pathologic findings of these degenerations were same as or similar to those of the degenerations in human peripheral retina. CONCLUSIONS:The atrophic retinal degenerations that are similar to human' s are present at peripheral fundus in canine eyes. （Chin J Ocul Fundus Dis,1996,12: 151-152）
