Abstract

A 5-year-old Siamese cat was presented at the Veterinary Medical Teaching Hospital in Seoul National University with visual impairment. The cat was blind and its pupillary light reflexes were sluggish OU. While there were no remarkable findings in the anterior segment, generalized tapetal hyperreflectivity and retinal vascular attenuation were observed in the posterior segment of both eyes. Any historical significance and clinical symptoms suggestive of infection or inflammation were absent. All of the above findings strongly indicated a diagnosis of hereditary retinal degeneration in the cat. This clinical case report demonstrates the possibility of the presence of feline hereditary retinal degeneration in Korea. Awareness of the condition should be raised to prevent the spread of hereditary retinopathy in the Korean cat population.

5살 샴 고양이가 시력 저하를 주증으로 내원하였다. 안검사 상 양안 실명했으며, 동공 빛 반사는 양안 모두 저하되어 있었다. 전안부에는 이상 소견이 없었지만, 안저 검사에서 양안의 반사판 과반사와 망막 혈관 위축이 관찰되었다. 문진 상 점진적인 시력 소실을 보였으며, 신체 검사 상 감염이나 염증을 의심할만한 증거가 확인되지 않았으므로 이에 유전성 망막 변성으로 진단하였다. 이 증례는 한국 샴 고양이 집단에 유전성 망막 변성을 일으키는 유전자가 도입되었을 가능성을 시사하므로 번식에 있어 주의를 요한다.
