Surgical Correction of a Corneal Perforation in an Alpaca (Lama Pacos)

Abstract

Likely because of trauma, an adult alpaca (Lama pacos) sustained a corneal perforation with a prolapsed iris. Because of the severity of the lesion, a pedicle conjunctival graft was performed. The structural integrity of the cornea was reestablished, and 10 mo postoperatively, the affected eye appeared to have good vision and only a small corneal scar remained.

Corneal sensitivity in healthy, immature, and adult alpacas

“…In the United States, alpacas ( Lama pacos ) have become increasingly popular show, pet, and production animals. Ulcerative keratitis is one of the most frequently diagnosed ocular conditions in camelids 1,2 . The increased prevalence of corneal disease in camelids may be related to the large size and lateral position of the globes in these species, predisposing them to corneal trauma.…”

In a survey of 29 alpacas, three had corneal scars that appeared to be secondary to trauma or corneal inflammation.…”

Disorders of the Neurologic System and Special Senses

“…Perforating ulcers or wounds may be repaired surgically as well. 135 With chronic or severe ulceration, some residual corneal scarring may exist. 129 In rare cases, proliferative epidermal cysts will form.…”

Ocular Surgery

“…Conjunctival pedicle flaps have been used successfully to seal these defects and facilitate healing of the cornea of camelid patients. 1,2 This procedure is done under general anesthesia and is greatly improved with the use of an operating microscope to ease suture placement. The edges of the defect are carefully debrided and any protruding tissue (e.g.…”
