Cataract aspects and stages in dogs- Literature Review

Abstract

Cataract is a ophthalmopathy characterized by opacity in the lens, classified according to their etiology, occurrence age, location, aspect and stage of development. Its formation is associated with aggregation of lens proteins, increase in insoluble proteins, osmotic stress, dysfunction in nutritional metabolism, changes in oxygen concentration, exposure to toxins and drugs and/or changes in ionic concentrations. Treatment of cataracts is surgery. The untreated and permanents cases in the eyes of dogs and cats can cause complications such as anterior and posterior dislocation of the lens, ocular perforation, uveitis induced lens, glaucoma, iris degeneration, retinal detachment, posterior synechiae and atrophy of the eyeball (phthisis bulbi). The objective of this work was to perform a literature review on the aspects and stages of cataract in dogs.
