About This Book

Comprehensive clinical manual detailing disorders of the nervous, genitourinary, ocular, and integumentary systems in domestic animals. It begins with principles of neural control and general symptomatology, classifying motor, sensory, and psychic disturbances and methods for localizing lesions. The text describes specific conditions such as seizures, paralysis, meningitis, intracranial hemorrhage, tumors, and toxicoses, and outlines diagnostic signs and pathological causes. Later sections address urine analysis and renal disease, urinary tract inflammation and calculi, and diseases of the eye, skin, and constitutional systems, combining pathological description with clinical signs, differential diagnosis, and practical guidance for examination and interpretation.

TUMORS OF THE RETINA.

Eversbusch found subretinal cysts in a 24 year old horse, Merkel and others have found similar bodies in old dogs and cattle. Sarcomata and melanosarcoma are found on the surface of the choroid in gray horses, implicating the retina. The only remedy is enucleation of the bulb.
