{Abstract}: OBJECTIVE: To report on the outcome of subsequent interventions after failed initial intervention for primary congenital glaucoma (PCG).
METHODS: Retrospective chart review of children presenting with PCG and failed the initial glaucoma surgery in Alexandria Main University Hospital from 2005 to 2017. The data included demographics, preoperative, operative and postoperative clinical characteristics. Success was defined as IOP<16mmHg and <20% from the presenting IOP and C/D ratio like or better than presentation.
RESULTS: The charts of 531 (260 right, 49%) eyes of 360 (224 males, 62%) children presenting with PCG and failed the initial glaucoma surgery (58 [31 right, 53%] eyes [10.9%] of 50 [28 males, 56%] children) revealed that at initial presentation, the mean±standard deviation (range, median) of the age of the children subjected to one successful glaucoma procedure and the study children was 8.6±11.7 (0.6-109, 5.2) and 4.9±6.1 (0.5-34.4, 3.0) months, respectively. Each of the study eyes was subjected to 2.6±0.8 (2-5.2) glaucoma procedures. The mean±standard deviation (range, median) duration between the initial and second glaucoma surgery and the duration of follow-up was 6.9±7.8 (0.7-39,3.9) and 61.5±32.1 (12.0-139.1, 60.1) months, respectively. At the final follow-up visit success was reported in 41 (70.1%) eyes by IOP<16mmHg criterion, 39 (67.2%) eyes by IOP>20% reduction criterion and in 28 (out of 35 eyes, 80.0%) by the optic nerve condition (C/D ratio) criterion. Success by all 3 criteria was reported in 25 (out of 35 eyes, 71%) eyes.
CONCLUSIONS: A repeat glaucoma surgical procedure maybe needed in up to 11% of operated PCG eyes, with the subsequent glaucoma surgical procedures being successful by about 70%.
