Fundoscopic normal variations of the retina in Turkish sheepdogs and multifocal retinal dysplasia: A comparative study in Akbash and Kangal breeds

Öz:

Bu çalışmada Türk çoban köpeklerinin (Akbaş ve Kangal) normal fundoskopik variyasyonları ve genetik retinal hastalıkları değerlendirildi. Otuzbeş Akbaş ve 35 Kangalda karşılaştırmalı olarak elde edilen sonuçlara göre, Akbaşlarda % 65 oranında mavi renkli, Kangallarda % 60 oranında sarı-yeşil renkli tapetal bölgelerin bulunduğu saptandı. Her iki grupta da albunizm, subalbunizme ve progresif retinal atrofiyi düşündürecek fundoskopik ve klinik belirtilere rastlanmadı. Ancak Akbaşlarda % 17,1, Kangallarda % 5,4 oranında multifokal retina displazisi gözlendi. Tipik fundoskopik görünümlerinde olan bu lezyonların tamamının dişi köpeklerde bulunması rastlantı olarak yorumlandı. Herhangi bir görüş kusuruna yol açmayan bu primer retina displazilerinin, Akbaşlarda Kangallara göre 3 kat fazla olması dikkate değer bulundu.

Öz:

In this study, normal fundoscopic variations and genetic retinal diseases of Turkish sheepdogs (Akbash and Kangal) have been assessed. According to comparative results obtained from 35 Akbash and 35 Kangal dogs, it was determined that blue tapetal regions were present at a rate of 65% in the Akbash breed and yellow-green tapetal regions were present at a rate of 60% in the Kangal breed. No fundoscopic or clinical sign suggesting albunism, subalbunism or progressive retinal atrophy was observed in either group. However, multifocal retina dysplasia was seen at a rate of 17.1% in the Akbash breed and 5.4% in the Kangal breed. The fact that all of these lesions, which presented typical fundoscopic appearance, were seen in females was interpreted as coincidental. It was of particular interest that these retinal dysplasias, which did not disrupt sight, occurred 3 times more in the Akbash breed compared to the Kangal breed.
