Abstract
To describe the technique and demonstrate the utility and outcomes of using a thick 3-0 Prolene ripcord in the lumen of a Baerveldt-350 aqueous shunt until after the ligature suture dissolves. Single-center, noncontrolled, retrospective case series. A total of 50 eyes from 50 patients with glaucoma undergoing placement of Baerveldt-350 aqueous shunts with 3-0 Prolene ripcords. A retrospective chart review was performed for all eyes of adult patients that had undergone a Baerveldt-350 aqueous shunt placement by a single surgeon at a single academic center between October 1, 2019 and June 30,2022. Data collected included demographic and clinical characteristics of the patients, preoperative and postoperative clinical data including intraocular pressure (IOP) and glaucoma medications, postoperative timepoints of ligature suture dissolution, and timepoints of 3-0 Prolene ripcord removal or whether they were permanently left in place. In total, 50 eyes from 50 patients were included; mean age was 69.5 years, 54.0% of patients were female, 92% of patients were Black, and 66% of eyes had primary open-angle glaucoma. Twenty-six of 50 (52%) eyes had ripcord removal at the soonest postoperative visit after spontaneous ligature dissolution, 19/50 (38%) eyes had delayed ripcord removal, and 5/50 (10%) eyes had no ripcord removal. There were no cases of hypotony-associated complications (shallow anterior chamber, hypotony maculopathy, choroidal effusion, suprachoroidal hemorrhage) in this subgroup of eyes that underwent no ripcord removal. Our results demonstrate that routine use of a 3-0 Prolene ripcord to partially occlude the lumen of a Baerveldt-350 is a useful strategy to minimize sudden hypotony-associated complications when the ligature suture dissolves. This strategy allows for a more controlled postoperative course and a safe 2-step decrease in IOP (1: when the ligature dissolves, and 2: when the ripcord is removed).
