Pediatric glaucoma in aniridia in a population of Egyptian children.

PURPOSE: To report on the incidence, characteristics, and treatment of glaucoma in association with aniridia in a population of Egyptian children.

METHODS

A retrospective chart review was conducted of children (<18 years of age) presenting with aniridia between 2007 and 2022. Diagnosis of glaucoma was based on cup:disk ratio (>0.3) and IOP (>16 mm Hg). Success of glaucoma surgery was defined as IOP ≤16 mm Hg and stable or regressing cup:disk ratio.

RESULTS

A total of 93 eyes of 47 children were included. The mean patient age at presentation was 41.2 ± 44.7 months. The mean intraocular pressure (IOP), corneal diameter, cup:disk ratio, and axial length on presentation were 16.4 ± 10.3 mm Hg, 11.4 ± 1.3 mm, 0.4 ± 0.3, and 22.43 ± 2.6 mm Hg. Of eyes with IOP and cup:disk ratio data at presentation, 23 (30%) were diagnosed with glaucoma. Fourteen eyes underwent surgery after presentation; follow-up data were available for half the remaining eyes. At the final follow-up, glaucoma was present in 20 eyes (49%). Glaucoma surgery was performed in 17 eyes, with a complete or qualified success rate of 82.4% at final follow-up, with 15 eyes having at least 12 months' follow-up.

CONCLUSIONS

In this study cohort, children with aniridia presented at around 3 years of age, with glaucoma at presentation in almost one-third of the cases.
