Clinical and morphological analysis of eye TUMORS AND EYES AUXILIARY PARTS IN DOGS
In spite of eye tumors in dogs are relatively rare, study of their clinical manifestations and morphological features are scientific and practical important. Neoplasm even in small quantities can destroy eye structure and disrupt its function. We performed a clinical and histological analysis of 278 cases of tumors of different localization in dogs received in veterinary clinics of Bishkek. The overall incidence of dogs ocular tumors was 4, 27% percent (12 cases) of the total canine cases. Malignant tumors were 3 cases (25%) and benign tumors - 9 cases (75%). Breed or reproductive predisposition of dogs to new growths of eyes was not detected. The tumor of eyes occurs in dogs of all ages, but is more often observed at dogs up to 6 years old. There were neoplasms mainly with lesions of the upper and lower eyelids (7 cases), the third eyelid (3 cases) and the eyeball (2 cases). During a clinical examination in dogs we found: tearing, swelling and hyperemia of conjunctiva, in some cases, mucopurulent discharge. The neoplasms of eyelids were the oval-flattened form, dense, soft, jellylike in consistence, mobile, from light pink till brown in color, generally small in size. The following tumors were diagnosed histologically: squamous papilloma, basal cell papilloma, soft fibroma, solid fibroma, sebaceous adenoma, lacrimal adenoma, prolymphocytic lymphosarcoma and melanoma.
