Characteristics of Corneal Endothelium in Axenfeld Rieger Spectrum.

PURPOSE: The purpose of this study was to compare the corneal endothelial characteristics in Axenfeld anomaly (AXA), Rieger anomaly (RGA), and Axenfeld-Rieger anomaly/syndrome with age-matched healthy controls. METHODS: This is a retrospective, comparative case-control study of 52 eyes of 30 patients with AXA/RGA and AXA/S and 36 controls. RESULTS: Median age at endothelial imaging was 21.5 years (interquartile range, 13.8-33.3 years). In the study group, the mean endothelial cell density (ECD) was 2112.4 ± 78.5 cells/mm 2 , the mean cell area (MCA) was 526.9 ± 28.5 µm 2 , and the coefficient of variation of cell size was 41.2 ± 1.8%. The ECD was significantly (all, P < 0.0001) lower than controls, while MCA ( P < 0.0001), SD of cell size ( P < 0.0001), and maximum cell area ( P = 0.0007) were significantly higher than controls. Four eyes of 3 patients had guttae on slitlamp evaluation and endothelial imaging. There were no differences in the corneal endothelial characteristics among the clinical subtypes. CONCLUSIONS: Patients with AXA, RGA, and Axenfeld-Rieger anomaly/syndrome have lower ECD and increased MCA compared with normal eyes. The reduced ECD associated with inherent anterior segment alterations can predispose to the risk of postcataract surgery endothelial decompensation in these eyes. The association of guttae in some eyes needs further investigational studies.

Outcomes after surgical removal of anterior epi-capsular plaque associated with persistent pupillary membranes in children.

INTRODUCTION: Anteriorepi-capsular plaque (ACP) is usually eccentric and is associated with persistent iris strands arising from the collarette. Outcomes of lens preserving ACP peeling along with removal of persistent pupillary membrane (PPM) strands have seldom been reported with only a few cases within some case series appearing in the literature. Herein we aim to report outcome after surgical removal of ACP associated with PPM in children. METHODS: Research was done in three different Institutes. Charts were reviewed for all children who had undergone ACP removal surgery from 2010. Age at surgery, gender, preoperative best corrected visual acuity (BCVA), preoperative refraction, morphologic details of ACP, intraoperative complications, ophthalmic viscosurgical device use, age at last follow-up, postoperative complications, and postoperative BCVA were reviewed. RESULTS: A total of 16 patients, 10 male and 6 female, were included in study. Age at surgery ranged from 2 to 86 months old. Age at last follow up visit ranged from 2 to 14 years old. Postoperative complications were not observed in any of the 16 patients. Specifically, in all patients the crystalline lens remained clear at the last follow up visit. CONCLUSIONS: Congenital ACP of the lens associated with PPM and clear lens can be safely surgically removed with a very low risk of iatrogenic cataract in the early period after surgery.
