The frequency of secondary glaucoma in patients with iridocorneal endothelial syndrome in correlation with the presence of uveal ectropion

Abstract

Introduction/Objective Iridocorneal endothelial (ICE) syndrome incudes 3 clinical forms: progressive iris atrophy, Chandler’s syndrome, and Cogan–Reese syndrome. It is characterized by various degrees of iris atrophy, corneal endothelial changes, uveal ectropion, corectopia, peripheral anterior synechiae (PAS) and secondary glaucoma. The aim of the study was to illustrate forms of ICE syndrome, determine frequency of secondary glaucoma with emphasis on cases with uveal ectropion, analyze response to medicament treatment and the need for surgical treatment in intraocular pressure (IOP) control. Methods Patients underwent slit lamp examination, applanation tonometry, gonioscopy, ophthalmoscopy, Humphrey visual field testing and Heidelberg retina tomography. Patients were divided into two groups: group I, without uveal ectropion (22 patients) and group II, with uveal ectropion (14 patients). Results A total of 36 patients were examined in a 10-year period. The average age was 38 years, male to female ratio 1:2. Secondary glaucoma was confirmed in 26 (72.2%) patients, out of which 12 (54.5%) in group I and 14 (100%) in group II. PAS were more frequent in group II. In group I, mean initial IOP was 37 mmHg, and after medicament treatment 26 mmHg. Secondary glaucoma was controlled in 50% and remaining 50% underwent surgical treatment. In group II, mean initial IOP was 49 mmHg, and after medicament treatment 32 mmHg. All 14 patients (100%) underwent surgical treatment in order to achieve IOP control. Conclusion ICE syndrome is a rare, progressive disease, with high incidence of secondary glaucoma, which is more frequent in cases with uveal ectropion. In these cases, medicament treatment is not effective and trabeculectomy with antimetabolite application is necessary. © 2017, Serbia Medical Society. All rights reserved.
