Porcine small intestinal submucosa (SIS) was used, in conjunction with a conjunctival graft, to repair a full thickness corneoscleral defect resulting from the excision of a limbal melanoma in a German shepherd dog. The SIS was found to provide adequate mechanical support and to act as a suitable physical barrier in place of the excised cornea and sclera. Corneal vascularisation was present distant to the graft by two weeks postoperatively but this was effectively controlled with topical cyclosporin. By six weeks postoperatively, the graft had become incorporated into the cornea and sclera, and the associated corneal neovascularisation had resolved. From this initial case, porcine SIS would appear to be a suitable material for the repair of corneoscleral defects in dogs.

Unilateral corneolimbal squamous cell carcinoma associated with intraocular invasion is described in two unrelated cats. The diagnosis was made on histopathological examination of the enucleated globes in both cases. Findings revealed squamous cell carcinoma infiltrating the limbus, adjacent cornea, and sclera with associated intraocular invasion at the level of the limbus.

1998) Urethral sphincter mechanism incompetence in the male dog: importance of bladder neck position, proximal urethral length and castration.

Extensive skin loss from the forelimb of a Border collie was repaired by a microvascular caudal superficial epigastric flap, with secondary meshing of the flap to increase coverage. The caudal superficial epigastric artery and vein were anastomosed to the brachial artery and vein. End-to-end anastomosis to the brachial artery and vein did not compromise peripheral blood flow, and no flap necrosis was observed after subsequent limited meshing of the flap.
