Van Kedilerinde Gözyaşı Üretiminin Fenol Kırmızısı Emdirilmiş İplik Testi ile Ölçülmesi

Bu çalışmanın amacı, sağlıklı Van kedilerinde normal gözyaşı salgı düzeylerinin PRT testi ile belirlenmesi ve gözyaşı düzeyi ile cinsiyet ve yaş arasındaki ilişkinin araştırılmasıdır. Çalışmada kliniğe getirilen ve muayene sonrası sağlıklı olduğuna karar verilen yirmi erişkin Van kedisi yer aldı. Bu kedilerde herhangi bir ilaç kullanılmadan test edilmiştir. Deneye katılan kedilerin yaşları iki ile beş yıl arasında değişmekte olup, ortalama yaş 3.25± 1.07'dir. Grupta 12 dişi ve 8 erkek kedi vardı. Test için ticari kitler kullanıldı. Van kedisi için ortalama PRT değeri 12.3±1.895 (9-18) mm/15 sn olarak belirlendi. Erkeklerde ortalama 11.875±1.246 (10-13) mm/15 sn. dişilerde ise ortalama 12.583±2.234 (9-18) mm/15 sn. olarak ölçüldü. Grupta dişi ve erkek ortalamaları arasında istatistiksel olarak anlamlı bir fark bulunmadı ve yaş arttıkça fark yoktu (p>0.05). Sonuç olarak, bu çalışmadaki PRT testi bulguları Van kedilerinin gözyaşı üretme kabiliyetini etkileyen göz hastalıklarının tanısında referans değer olarak kullanılabilir.

Measurement of Tear Production in Van Cats with The Phenol Red Thread Test

The aim of this study is to determine normal tear secretion levels in healthy Van cats by PRT test and to investigate the relationship between tear level and gender and age. Twenty adult Van cats, who were brought to the clinic and found to be healthy after examination, were included in the study. These cats were tested without the use of any medicine. The cats who took part in the experiment ranged in age from two to five years, with a mean age of 3.25± 1.07. There were 12 female cats and 8 male cats in the group. Commercial kits were utilized for the testing. The mean PRT value for the Van cat was determined as 12.3±1.895 (9-18) mm/15 sec. Males had a mean of 11.875±1.246 (10-13) mm/15 sec. and females had a mean of 12.583±2.234 (9-18) mm/15 sec. There was no statistically significant difference in the mean of males and females in the group and no difference as age increased (p>0.05). In conclusion, the PRT test findings in this study can be used as reference values in the diagnosis of eye diseases affecting the tear production ability of Van cats.
