This study was performed to investigate the normal ocular fundus in 30 Korean native goats. The shape of two peaks of a mountain was shown in the tapetal fundus which was mostly greenish-blue color. The nontapetal fundus which was differentiated from the tapetal fundus, was generally a uniform shade with dark blue. The optic disc was nearly round and varied in color : orange, gray, tan and various combinations. It was mostly located at the junctional area of the nontapetal and the tapetal fundus. In the retinal vasculature, three or four major arterioles and two or three major venules emerged from the optic disc and the arterioles could be distinguished from the venules. The superior arteriole and venule in the tapetal fundus did not twist each other.

From February to September in 1996, a lot of blind cattle were reported in Dangjin Area of Chungnam Province. Blindness were observed in the 143 calves of the 1,496 calves from 79 farms. Blind cattle were found only in the farms where green pasture was not fed. After administration of vitamin A as the type of feed additives and parenteral injection, the blindness cases were not occurred in those farms. Both pupils were totally dilated with the absence of pupillary light reflex in all blind cattle. In the ophthalmoscopic examination, the fundus revealed multi focal linear white mottling which was more severe in nontapetal fundus than tapetal fundus. Serum vitamin A concentration was as low as 4.1 ,$\mu\textrm{g}$/dl in the calves of the affected farms. Narrowing of optic foramen, retinal degeneration and optic disc atrophy were shown in pathological findings.

A 2-year-old intact female Bengal cat was presented with a 6-month history of visual impairment. The cat manifested bilateral negative menace responses and dazzle reflexes and sluggish pupillary light reflexes. Bilateral fundus changes included generalized tapetal hyperreflectivity, advanced retinal vascular attenuation, and increased pallor of the optic disc. A diagnosis of bilateral retinal degeneration was made. The clinical findings suggest that the investigated Bengal cat was most likely to have an inherited retinal degeneration. Further studies of the Bengal cat breed are needed to determine the prevalence of inherited retinal degeneration in this breed in Korea.
