Source: ClinicalTrials.gov · Last updated 3 Sept 2026
Brief summary (registry, in English)
This is a research study to find out if removing the ripcord from a glaucoma drainage device more than 3 months after it has been placed has any effect on intraocular pressure. Participation in research studies is voluntary. The ripcord will be removed at a routine glaucoma care visit and intraocular pressure will be measured before removal, 30 minutes following, and at 1 week, 6 weeks and 3-month intervals during regular clinic visits.
