%X In the present study, type and incidence of retinal abnormalities occurring in newborn calves (0-3 months) and its possible reasons were evaluated by routine ophthalmic and ophthalmic fundus examination in Kars region. The study was performed in 300 calves with various breeds, age (0-3 months) and sex. In all cases, examination of the fundus of the eye was performed after the midriasis with Atropine. During the fundic examination of optic disc, tapetal and non-tapetal areas and retinal vascularity were evaluated. Normal and abnormal findings were recorded and photographed. Clinical examination showed that 287 of 300 (95.66%) calves were clinically normal, bilateral full blindness were observed in 13 calves (4.33%). Retinal and optic disk problems were present in 9 cases (3%), 4 cases (1.33%) were free of retinal and optic disc problems. Optic disc hypoplasia, retinal degeneration and myelinization (1 case), optic neuritis (1 case), optic disc hypoplasia (2 cases), retinal hemorrhagia due to corioretinitis (1 case), papilledema (1 case), retinal degeneration (1 case), papilledema and retinal degeneration (1 case), optic neuritis and retinal hemorrhagia in one eye, optic neuritis and partial retinal separation were other findings observed in nine case with eyesight problems. In conclusion, in the present study the incidence of eyesight problems that is a significant problem in cattle breeding of our region and normal fundic variation of various cattle breeds were determined. A variety of fundic problems were also determined in animals with sight problems
