ABSTRACT
PURPOSE: This retrospective cohort compared the cumulative probability of success for glaucoma drainage device (GDD) implantation in pediatric and adult patients.
STUDY DESIGN: This retrospective study enrolled adult and pediatric patients who had received a GDD between January 1, 1985 and December 31, 2017.
METHODS: Kaplan-Meier method was used to estimate the cumulative probability of success in the pediatric and adult patients. Successful intraocular pressure (IOP) control was defined as (i) a 20% reduction from baseline and (ii) IOP>6 and <18. Inadequate IOP control and failure were defined as a violation of these two criteria over two consecutive visits. Cox proportional hazards models enabled assessing the influence of sex, GDD location, and GDD type on IOP control.
RESULTS: A total of 425 adult eyes from 372 individuals and 41 pediatric eyes from 28 individuals were included. The median follow-up time was 55 months for adults and 87 months for children. Superior temporal GDD placement was most employed for both (p=0.16). Adults were more likely to receive a Baerveldt 350 (p=0.04) and children were more likely to receive an Ahmed S2 (p<0.001). Adults and children had a median survival time of 2.99 and 0.82, respectively, and did not have a statistically significant difference in GDD failure rate (p=0.18). Additionally, sex, GDD location, and GDD type did not affect the success rate.
CONCLUSIONS: Children and adults had a similar cumulative probability of success following GDD implantation. This study found that GDD type, GDD location, and glaucoma type did not influence the probability of successful IOP control.
