Abstract

Considering the importance of the flock of Alentejo sheep, the goal of this study was to determine the average values of eye examinations, evaluate the ophthalmoscopic features and fluorescein staining for Merino sheep from Alentejo region, in Portugal. The 48 eyes of 24 healthy, female sheep belonging to the sheep flock at the University of Évora were evaluated. The average values obtained for Schirmer tear test (STT) were 19.0 ± 5.22 mm/min, with a reduction of tear production varying according to the age of the animal, for tear pH were 7.7 ± 0.48 and for intraocular pressure (IOP) was 12.7 ± 3.03 mmHg. Fundus aspects were observed in the tapetal area with shades of blue, green and yellow. The optic disc was predominantly in the transition area between tapetal and non-tapetal regions of elliptical shape, with holoangiotic vascular pattern. None of the animals showed fluorescein staining on the ocular surface. In the context of the investigation, these data may be useful to improve the clinical approach to the species and reference standards of the exam’s values

葡萄牙阿连特茹地区羊的眼科评价

考虑到阿连特霍羊群的重要性，本研究的目的是确定葡萄牙阿连特乔地区梅里诺羊的眼部检查平均值，评估其眼科特征和荧光素染色。对埃沃拉大学羊群中24只健康雌性绵羊的48只眼睛进行了评估。Schirmer泪液试验（STT）获得的平均值为19.0±5.22 mm/min，泪液pH值为7.7±0.48，眼压（IOP）为12.7±3.03 mmHg，泪液产生的减少因动物年龄而异。在绒毡层区域观察到眼底，颜色为蓝色、绿色和黄色。视盘主要位于椭圆形绒毡层和非绒毡层区域之间的过渡区，具有全血管性血管模式。没有一只动物的眼表面出现荧光素染色。在调查的背景下，这些数据可能有助于改进物种的临床方法和检查值的参考标准
