Transcorneal Anterior Chamber Laser Cyclophotocoagulation for the Treatment of Secondary Glaucoma with Lens Subluxation in a Dog

Abstract

We applied a green laser transcorneally via the anterior chamber to the ciliary body for treatment of complicated glaucoma with lens luxation in a dog. The ciliary body was able to be observed through the interspace between the iris and the dislocated lens. Intraocular pressure (IOP) stayed around 30‐38 mmHg for 3 months prior to the procedure, and 15‐21 mmHg for 3 months following the procedure, but gradually rose to 29 mmHg in the next 3 months. There was no obvious symptom of uveitis following the procedure. Although this procedure is limited to the unlikely situation where the ciliary body is observable through a narrow space, it can reduce damage to the surrounding tissue compared with transscleral cyclophotocoagulation, and can reduce the cost compared with endoscopic cyclophotocoagulation.
