PRéCIS:: Kaplan-Meier analysis was used to compare the rate of corneal grafting after glaucoma drainage device placement in pediatric and adult patients. Adults were at an increased risk of receiving a corneal graft after device placement. PURPOSE:: The goal of this study was to compare the rate of corneal graft implantation after glaucoma drainage device placement in pediatric and adult patients. PATIENTS:: Patients receiving a glaucoma drainage device between January 1, 1985 and December 31, 2017 were selected from the medical records. Patients receiving their first device while <18 years of age were considered children for the extent of the study. METHODS:: We compared the rate of receiving a corneal graft after glaucoma drainage device implantation using Kaplan-Meier analysis. Baseline patient characteristics and surgical characteristics were compared using a generalized estimating equation. RESULTS:: Corneal grafting occurred in 8.6% of adults and 4.7% of children from the original cohort.The rate of receiving a corneal graft at 5, 10, and 15 years was 9.4%, 16.8%, 39.4% and 1.6%, 1.6%, 12.5% for adults and children respectively. However, certain characteristics were different between the two groups. CONCLUSION:: Adult patients were more likely to receive a corneal graft after glaucoma drainage device placement. However, pediatric and adult patients differed in the prevalence of preexisting corneal disease, glaucoma type, glaucoma drainage device type used, and types of previous surgeries. Elucidation of the impact of these factors on corneal graft rate requires a larger cohort size.
