Surgery for glaucoma.

Most cases of glaucoma in small animals ultimately require surgical treatment for long-term control of intraocular pressure. Surgical procedures that have the potential to preserve vision in acute cases are categorized into those that reduce aqueous production (cyclodestructive techniques). Salvage procedures for irreversibly blind eyes include enucleation, implantation of an intraocular prosthesis, and pharmacologic ciliary body ablation. The indications, surgical technique, and complications of these procedures are discussed in this article.
