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.

OCCLUDED PUPIL.

This has been frequently found in horses as a sequel of iritis, and permanent adhesion of the contracted iris to the front of the lens capsule. It is in short, a posterior synechia with closure of the pupil. The lens and its capsule are usually opaque so that there would be no gain in detachment of the iris. If, however, there is reason to conclude that any part of the lens is still transparent, the performance of iridectomy over this portion, would produce a new aperture for the entrance of light.
