Microphthalmia, congenital cataracts, posterior lenticonus, and retinal dysplasia were observed in members of 3 litters of Akita puppies thought to be related to a common male ancestor. The electroretinograms of 3 clinically affected puppies were normal. Histological examination of 6 microphthalmic animals revealed nuclear and cortical cataract with multiple retinal folds and rosettes predominantly overlying the tapetum lucidum. Posterior lenticonus was observed histologically in 3 of the 6 puppies.
在3窝秋田幼犬中观察到小眼症、先天性白内障、晶状体后圆锥以及视网膜发育异常，这些幼犬被认为与一个共同的雄性祖先有关。3只临床患病幼犬的视网膜电图正常。对6只小眼症动物进行组织学检查发现，核性和皮质性白内障伴有多个视网膜褶皱和玫瑰花结，主要覆盖在脉络膜反光层上。在6只幼犬中的3只组织学检查中观察到晶状体后圆锥。
