Electroretinographic evaluation of photoreceptor cells in Turkish shepherd dogs

Bu çalışmada 20 Türk Çoban köpeğinin (TÇK) toplam 40 gözünde, ISCEV standartlarını uygulayarak elde ettiğimiz ERG sonuçları değerlendirilmiştir. Buna göre a dalga boyu 1.298±0.208 mikrovolt, b dalga boyu 7.670±0.846 mikrovolt, a dalgası için implisit zamanı 70.268±11.840 milisaniye, b dalgası için implisit zamanı 97.072±12.696 milisaniye olarak belirlendi. TÇK’inde genetik bir retina hastalığına ilişkin, klinik, funduskopik ya da ERG’de bir belirti gözlenmemiştir. Çalışma içerisinde, tek ya da çift taraflı körlük bulunan 10 farklı ırktan klinik olgunun, funduskopik ve ERG verileri de, TÇK’inde elde ettiğimiz değerlerin, bu ırkta yapılacak retina çalışmalarında, referans değerler olarak kullanılabileceğini göstermiştir.

Türk Çoban köpeklerinde retina fotoreseptör hücrelerinin elektroretinografik olarak değerlendirilmesi

In this study, the electroretinography (ERG) results which are obtained from a total of 40 eyes in 20 Turkish shepherd dogs (TSDs) which meet the standards of ISCEV were evaluated. Accordingly, amplitute of the a-wave 1.298±0.208 microvolt, amplitute of the b-wave 7.670±0.846 microvolt, implicit time of the a-wave 70.268±11.840 milisecond, implicit time of the b-wave 97.072±12.696 milisecond were determined. There is no clinical, funduscopic or ERG evidence of a genetic retina disorder in TSDs. The funduscopic and ERG datas which obtained from 10 patient in different breed which have single-or double sidedblindness revealed that the results of our study can be used as a reference value in further studies about retina in TSDs.
