Objective: To report ocular examination findings before and after total ear canal ablation and lateral bulla osteotomy (TECALBO) and ventral bulla osteotomy (VBO) in cats and dogs.

Methods: At The Ohio State University and MedVet Columbus, ophthalmic examinations were performed on client-owned animals for which a TECALBO or VBO was indicated. Examination findings and postoperative complications relating to ophthalmic and/or neuro-ophthalmic diseases were recorded prior to surgery (T0) and at 1 day (T1), 2 to 3 weeks (T14), and ± 2 months (T60) postoperatively.

American alligators () are an important apex predator of semiaquatic habitats of the southern United States. Commercial alligator farming has grown in the last several decades, leading to a need to understand the health conditions that affect this species to ensure appropriate management and welfare. The aims of this study were 1) to establish and describe normative data including results of common ophthalmic diagnostic tests and conjunctival flora, 2) document ocular pathology in this population, and 3) assess the effect of topical rocuronium bromide and 10% phenylephrine for facilitating pharmacologic mydriasis.

Monogenean ectoparasitic flatworm infestations, particularly in closely confined populations, can result in severe epizootic disease that is often devastating and occasionally fatal. This case series describes a population of cownose rays () ( = 52) housed in an aquarium touch-tank exhibit that presented with severe ocular disease due to infestation with monogeneans, presumably of the Capsilidae family. The most severely affected individuals ( = 9), including several cases with bilaterally ruptured corneas, underwent serial examinations prior to and following treatment with praziquantel, systemic antibiotics, and corticosteroids.

A 9-year-old, female spayed domestic short-haired cat was presented with a 4-year history of bilateral lipogranulomatous conjunctivitis (LGC), which was confirmed via histopathology. Thirteen months following the initial biopsy, the cat was presented with a rapidly progressive mass lesion of the palpebral conjunctiva of the right eye. A surgical debulking, followed 1 month later by exenteration after marked regrowth of the mass confirmed fibrosarcoma.
