Melting corneal ulcer management in a greater one-horned rhinoceros (Rhinoceros unicornis).

Acute unilateral keratomalacia, probably secondary to trauma, occurred in a greater one-horned rhinoceros (Rhinoceros unicornis) transferred between zoologic facilities. Following 2 days of medical treatment, a 360 degrees conjunctival surgical graft was performed. Staphylococcus and yeast were isolated from a perioperative culture of the affected eye and were treated with antimicrobials. There was rapid healing and minimal midcorneal scar formation with peripheral corneal clarity.
