Hereditary eye abnormality in Rocky Mountain Horses. - Circulation

PURPOSE: To quantify the incident and describe eye aberrations in a cross-section of the Rocky Mountain Horse populations. Five hundred and fourteen Rocky Mountain Horse. Six horse eyelets were removed for histological investigation. RESULTS: The most common cases were found in rear eye, cyst of ziliary bodies and cyst of periphery eye (249 horses), which were always temporal.

Crooked strips of pigment coated retroaepithelium, which extend from the periphery of the temporary retina, indicated the limit of prior separation in 189 equidae. Reticular dyplasia was found in 125 equidae. A number of eye abnormalities were observed in 71 equidae and were always double sided and symmetric. The affected eye had a large, clear, protruding horny skin with a seemingly small radii of curve, a low front ventricle, a miotical and dilated pupils and an Irishypoplasia.

Reactions to pupil irradiation were reduced or failure and pupil size could not increase after repeat insertion of mydriamines in equine patients with several eye conditions. Among the less common aberrations were peripherally abscessed irregular corneal growths and gingival necrosis.

Histological examinations of the eye confirmed the clinically correct presentation.
