Abstract

In the practice of an ophthalmic surgeon, patients with a large number of concomitant conditions after repeated surgical interventions are seen with increasingly frequency. One of the grave complications in such patients is secondary glaucoma with a refractory type of course. After successful compensation of intraocular pressure in such patients, the risk of complications increases many times, for example, protrusion of the Ahmed valve drainage tube, which becomes the entrance gate for infection, which can lead to endophthalmitis. This article presents clinical cases of surgical treatment of recurrent protrusion of the Ahmed valve drainage tube.
