Purpose: To develop a patient-reported outcome measure to assess the impact of glaucoma and treatment, including minimally invasive glaucoma surgery (MIGS).
Design: Observational study before and after concomitant cataract and Food and Drug Administration-approved implantable MIGS device surgery.
Setting: Survey administration was on a computer, iPad, or similar device.
Purpose: To describe the iSTAT (Intraluminal Suture Transfixed and Titratable) technique, an improvement on prior tube occlusion methods, allowing for variable flow.
Observations: A 76-year-old woman who underwent an uncomplicated glaucoma drainage device (GDD) placement for uncontrolled mixed mechanism glaucoma presented with hypotony 4 years post-operatively. The iSTAT technique was performed to adjust the flow in the GDD tube: a 4-0 polypropylene suture tip was blunted with a low-temperature cautery, creating a bulbed end that would occlude the tube.
