Clinical-ophthalmological and electroretinographic results were found, compared and evaluated in 73 dogs of 21 different breeds with signs of decreased vision or blindness. Cataracts were found in 51 dogs. In cases of non visible fundus electroretinography is an essential tool for evaluation of the retinal function. Otherwise clinical-ophthalmological examination is a sufficient diagnostic method, except for sudden acquired retinal degeneration (SARD). The pupillary light reflex is an important diagnostic criterion for evaluation of the reflex pathway, but has less importance for diagnosis of visual abilities. These can be examined by vision tests. In English cocker spaniels and miniature and toy poodles with cataracts a significant electroretinographic loss of retinal function was found. In respect to the breed and age of these dogs this functional deficit is recognized as a result of progressive retinal atrophy.
对73只来自21个不同品种、有视力下降或失明迹象的犬进行了临床眼科和视网膜电图检查结果的发现、比较和评估。51只犬发现有白内障。在眼底不可见的情况下，视网膜电图是评估视网膜功能的重要工具。否则，除了突然获得性视网膜变性（SARD）外，临床眼科检查是一种充分的诊断方法。瞳孔光反射是评估反射通路的重要诊断标准，但对视觉能力的诊断重要性较低。这些可以通过视力测试来检查。在患有白内障的英国可卡犬以及迷你和玩具贵宾犬中，发现视网膜功能有明显的视网膜电图损失。就这些犬的品种和年龄而言，这种功能缺陷被认为是进行性视网膜萎缩的结果。
