The prepurchase examination.

The prepurchase examination is performed to aid a prospective purchaser in determining the suitability of a specific patient for an anticipated use and, perhaps, an intended rider. The ophthalmic portion of that examination can be performed satisfactorily with minimal equipment by following a systematic protocol that includes examination of all segments of the globe and an evaluation of the patient's vision. Findings of the examination should be discussed with and made in writing to the buyer so that he or she can make an informed decision about the suitability of the purchase.

Fluorouracil as a treatment for corneal papilloma in a Malayan tapir.

A 26-year-old, wild caught, male Malayan tapir at the Miami Metrozoo with bilateral corneal papillomas was serially immobilized and given subconjunctival injections of fluorouracil. Over the course of 17 weeks five bilateral injections of 25 mg fluorouracil were given. This treatment caused regression of the corneal lesions as evidenced by decreased lesion diameter, decreased corneal vascularity, increased corneal clarity, and improved visual function.

Laboratory testing in pet avian medicine.

The importance of employing laboratory diagnostics in the examination of avian patients cannot be overemphasized. The physical examination alone is grossly insufficient. Many avian illnesses do not display external signs, and laboratory work is imperative in detecting them.
