Abstract

PURPOSE: To identify specific factors and outcomes associated with corneal edema and Haabs striae in primary congenital glaucoma (PCG). METHODS: The medical records of patients with PCG from 2011 to 2023 with >3 months' follow-up were reviewed retrospectively. Preoperative details and final outcomes were compared between eyes with and without corneal findings. The right eye of bilateral cases and the affected eye in unilateral cases were included. RESULTS: A total of 58 patients (104 eyes, 69% male) underwent initial angle surgery at an average age of 297 ± 368 (median, 134) days. Corneal edema and Haabs striae were present preoperatively in 72 (69%) eyes of 41 patients and 68 (65%) eyes of 39 patients, respectively. Patients with corneal edema presented at a younger age (P < 0.0001) and with shorter axial length (P = 0.01) than those without edema. Univariate analysis showed that corneal edema was associated with worse visual acuity at final follow-up (OR = 4.4; 95% CI, 1.2-25.3). Patients with Haabs striae were older than those without striae (P = 0.04). After angle surgery, corneal edema was present at 1 month in 71% (95% CI, 52-84), at 2 months in 26% (95% CI, 12-42), at 3 months in 16% (95% CI, 6-30), and at 1 year in 3% (95% CI, 0-13). Corneal opacification did not resolve in 4 eyes of 3 patients after >4 years of follow-up. CONCLUSIONS: In our study cohort, corneal edema resolved in the majority of PCG cases within 2-3 months of initial angle surgery but was associated with younger age at presentation and worse visual acuity at final follow-up.
