Secondary ab interno stenting to manage early tube-related hypotony.

Abstract

Trabeculectomy is the gold standard procedure to achieve control of intraocular pressure surgically. However, glaucoma drainage devices have their place in certain refractory glaucomas not amenable to control by the standard trabeculectomy. These devices come with their own set of complications, cognizance of which is critical to anticipate and manage appropriately. With the nonvalved devices, hypotony is one difficult problem to deal with. Several modifications have been described to manage refractory hypotony after tubes. We present here a simple, less invasive surgical technique of secondary ab interno suture stenting to manage tube-related early hypotony.
