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.

WOUNDS AND INFLAMMATION OF THE MEMBRANA NICTITANS.

Like other parts of the ocular apparatus, the third eyelid and gland of Harder are subject to accidental injuries of various kinds. What is worse, ignorant persons seeing the cartilage and membrane projected over the eye in ophthalmias and tetanus, have mistaken it for a morbid product and deliberately cut it off in part. The condition of the organ may be ascertained by parting the lids with the fingers and pressing gently on the front of the eyeball, when the nictitating membrane will be fully exposed.

If detached portions cannot be restored, but threaten to slough, or cause distortions or unsightly and irritating neoplasms they should be seized with forceps and snipped off with scissors. Otherwise the treatment consists in soothing astringent and anodyne Collyria as in conjunctivitis.
