Surgical Treatment of Canine Glaucoma: Cyclodestructive Techniques.

Medical and surgical management of canine glaucoma can be challenging. The goal of surgical treatment is to manipulate the inflow and/or outflow of aqueous humor. This article describes the inflow-reducing, cyclodestructive techniques. Diode cyclophotocoagulation is the most common cyclodestructive procedure performed in humans and animals. Diode laser energy can be applied via a transscleral (transscleral cyclophotocoagulation [TSCP]) or an endoscopic (endoscopic cyclophotocoagulation [ECP]) approach. ECP provides direct visualization of the targeted ciliary body, allowing safer and more titratable treatment than TSCP techniques, offering a better long-term prognosis for vision and intraocular pressure control. Advancements in diode laser therapy seem promising.
