Early Experience With Ahmed Clear Path Glaucoma Drainage Device in Childhood Glaucoma

Purpose: The aim was to evaluate the short-term outcomes of Ahmed clear path (ACP) valveless glaucoma drainage device in childhood glaucoma. Methods: Retrospective chart review of all patients 16 years or below with childhood glaucoma who had ACP implantation at Boston Children's Hospital from December 2019 to June 2020 with at least 6 months follow-up period. Results: The study included 7 eyes of 5 patients implanted by a single surgeon. The median follow-up was 12 months. The mean intraocular pressure (IOP) was reduced from 36 +/- 3.5 mm Hg on a mean of 2.7 +/- 0.6 glaucoma medications preoperatively to a mean IOP of 12.4 +/- 2.8 mm Hg (P<0.001) on a mean of 0.7 +/- 0.8 medications postoperatively at final follow-up (P=0.0009). Complete success was achieved in 4 eyes while qualified success was achieved in 3 eyes. Conclusion: The ACP glaucoma drainage device provided good short-term IOP control and technical advantages for implantation for pediatric eyes were observed.
