Inflammation of the deep structures of the eye in cattle, in particular the vasculature, is rarely diagnosed, the cure rate is very small, due to insufficient study of diseases of the vascular tract of the eye. Inflammation of the vascular tract (uveitis) in cattle rarely becomes the object of scientific research, despite its prevalence. Uveitis, like many other diseases of the organ of vision, often leads to blindness, such animals are forced to cull, causing significant economic damage to agriculture. The disease has been poorly studied in productive animals, with the exception of horses, however, the literary sources concerning uveitis in cattle are isolated and unsystematic. Bovine uveitis requires a thorough and comprehensive study of the features of etiopathogenesis, symptoms, diagnosis, and the development of rational therapy. The article highlights the clinical symptoms of fibrinous uveitis of streptococcal etiology in cattle. Fibrinous uveitis is characterized by involvement in the inflammatory process of the iris and ciliary body.
The disease is accompanied by sequential complications: synechia; cataracts and
glaucoma; lysis of the lens and vitreous body, which leads to subatrophy of the eye.
In the development of fibrinous uveitis streptococcal etiology should distinguish four
stages: inflammatory hyperemia of the choroid; stage of fibrinous exudation and synechia; glaucoma and cataract stage, lens resection; enophthalmos. The disease stages consist of two phases: the phase of septic inflammation; phase of autoimmunization (phakogenic uveitis).
