Plain-English summary
A horse had a silicone prosthesis, which is a type of artificial eye, placed inside its eye to help manage glaucoma, a condition that increases pressure in the eye. The glaucoma was thought to be linked to a problem with the lens, but it wasn't clear if it was the only cause. Previous treatments to lower the eye pressure didn't work, so the prosthesis was surgically inserted after removing the contents of the eye. This silicone prosthesis provides a cosmetic option for horses that have lost vision and are sensitive in that eye, instead of completely removing the eye.
Abstract
A 40-mm intraocular silicone prosthesis was placed in a horse's globe to control glaucoma. The glaucoma was suspected to be associated with a lens subluxation, but primary glaucoma could not be ruled out. Medical treatment and cyclocryotherapy had been attempted, but failed to decrease the intraocular pressure to a normal value. The prosthesis was placed, via a dorsal scleral incision, after removal of the intraocular contents. The size of the prosthesis was estimated from measurements of the horse's normal left globe and an enucleated, age-matched globe. Silicone prostheses offer a cosmetic alternative to enucleation of blind, sensitive globes in horses.
