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.

FOREIGN BODIES IN THE CORNEA.

In case of penetration of the cornea by thorns, thistles, glass, metal, etc., there usually follows inflammation with a red area around the offending object. If the foreign body is a piece of iron there is a brownish area caused by iron oxide. Focal or transillumination will usually reveal the object. Should both fail, a solution of fluorescin when applied will develop a greenish area around it.

Treatment may be made as advised by Gould by pressing a little antiseptic cotton to the front of the eye, so as to entangle and withdraw the foreign body when the eyeball is rolled. Failing in this we may cocainize the eye and remove the offending object with a small curette or spud. A careful focal illumination of the eye will enable the operator to see and remove the smallest particles without injury. Subsequent treatment is that of wounds.
