[Rehabilitation of patients with posttraumatic aniridia and secondary glaucoma]

Secondary glaucoma is one of the main problems of rehabilitation of patients with traumatic damage of the iris.

This study analyzes the long-term results of rehabilitation of patients with posttraumatic aniridia and glaucoma.

The study included 310 patients (310 eyes) with posttraumatic aniridia who had artificial iris-lens diaphragm (ILD) MIOL-Raduzhka implanted in 2002-2022. Before ILD implantation, 61 patients (22.8%) had secondary glaucoma. Among them 35 patients (11.3%) underwent various modifications of glaucoma surgery. In 26 patients (8.6%), intraocular pressure (IOP) was compensated medically before ILD implantation.

Until the third month after ILD implantation, there was a trend for IOP increase in some patients. Decompensation was noted in 8 (22.9%) out of 35 patients who had underwent glaucoma surgery. IOP decompensation was observed in 21 (80.8%) of 26 cases in patients with glaucoma compensated by drugs before ILD implantation. After ILD implantation, glaucoma appeared for the first time in 21 patients (6.8%) out of 310. In order to compensate IOP after ILD implantation, Ahmed valve implantation was performed most often - in 35 cases (70%) out of 50, deep sclerectomy - in 5 cases (10%), non-penetrating deep sclerectomy - in 4 cases (8%), micropulse transscleral laser cyclophotocoagulation (MP-TSCPC) - in 5 cases (10%), endoscopic cyclophotocoagulation (ECP) - in 1 case (2%).

ILD implantation in patients with posttraumatic aniridia and secondary glaucoma should be performed with IOP compensated without hypotensive therapy and not earlier than 6-12 months after glaucoma surgery. The most optimal glaucoma surgery types in this group of patients are Ahmed valve implantation and MP-TSCPC.
