Using 42 beagles (7 to 10 years old), ophthalmoscopic examinations were carried out in both anterior segment of eye and ocular fundus. The low light transparence was observed in all beagles in the present test. The low transparence is thought to becaused by the facilitation of reflectivity in the lens, since progressing lens nuclea sclerosis with aging was observed and no findings suggesting cataract were noted in the pathological examination.
In ophthalmoscopic and histopathological examinations we observed light tree-like cloudiness in the posterior surface of the lens, a decline in lens epithelial cell density, a marked formation of cysts surrounding the ora serrata in the retina, and hypertrophy of the basement membrane in the retinal capillary.
