Abstract:
Transscleral neodymium (Nd):YAG cyclophotocoagulation, a new cyclodestructive procedure for controlling intraocular pressure in patients with refractory glaucoma, is designed to penetrate the sclera and selectively destroy the ciliary body and processes without damaging the overlying tissue. Complications include conjunctival edema, corneal edema, iritis, gas in the anterior chamber, pain, hyphema, hypopyon, vitreous hemorrhage, and cataract. We present a case in which a patient developed focal areas of scleral thinning 6 weeks after transscleral Nd:YAG cyclophotocoagulation. The possibility of scleral damage or thinning should be kept in mind when performing the procedure.
