Staphyloma in a cat

Abstract

A unilateral scleral staphyloma in an 18-month-old, female spayed Domestic Short-haired cat was treated with excision, primary closure and fascial graft. Other ocular abnormalities noted on examination included iris coloboma, anterior cortical cataract, focal lens equator flattening and retinal dysplasia. The staphyloma was presumed to be congenital in origin.

Hydrocephalus, supratentorial diverticulum and agenesis of the interthalamic adhesion and corpus callosum in a cat: MRI findings, treatment and follow‐up

“…In addition, it could be present as a sporadic, unilateral defect due to non‐genetic factors such as exposure to high temperature, radiation, drugs, vitamin deficiency and exposure to infective agents during gestation 28 30–32. In cats, colobomas of the iris, fundus or both are rare 33 34. In this species, they can be associated with eyelid agenesis 34 35.…”

Repair of a scleral defect with an autogenous fascia lata graft in a dog

“…Many graft materials have been successfully used for both corneal and scleral grafting 1–10 . In animals they are considered interchangeable since the requirement for corneal clarity is less paramount than in humans.…”

“…Repair of damage to this ocular layer is commonly undertaken after disease, trauma or due to congenital lesions. Various grafting materials have been used to provide structural support to the repair 1–10 . This report describes the repair of a traumatic scleral defect using autogenous fascia lata.…”

Shope fibroma virus keratitis and spontaneous cataracts in a domestic rabbit

“…Other reasonable differentials that have been reported in other species included nodular granulomatous episcleritis or pseudotumor (fibrous histiocytoma, nodular fasciitis), 4,5 and neoplasia (primary, secondary) 6–9 . Additional considerations deemed less likely based on history and signalment included inflammatory, 10 infectious, 11 staphyloma, 12 papilloma, 13 or dermoid 14 …”
