Nutritional Keratopathy
Walden (1990) reports signs of vitamin A deficiency in adult rabbits to include a dull whitish patch developing on the axial cornea and spreading centrifugally to the limbus where pigmentation may develop. The recommended dose of vitamin A is based on the daily requirement which is 60 IU per kilogram of bodyweight. In the absence of treatment, keratitis and blindness may ensue.
Ulcerative Keratitis
Ulcerative keratitis may not always be due to external factors in rabbits. Williams (2006) describes persistent superficial epithelial erosion “similar to corneal basement membrane dystrophy of boxer dogs” and recommends fairlyaggressive treatment including grid, and superficial, keratectomy.
Keratoconjunctivitis Sicca
Keratoconjunctivitis sicca may be difficult to diagnose in rabbits – see notes on the use of the Schirmer 1 tear test.
