Anterior Segment Optical Coherence Tomography Microstent Positioning
Running, not enrolling
Conditions studied: Glaucoma, Stent Migration, Stent Dislodgement, Intraocular Pressure
In brief
The goal of this observational study is to learn about the long-term results of glaucoma stent surgery in men and women 18 or older who have had cataract and microstent surgery in the past 2 years at the Moran Eye Center. The main questions the study aims to answer are: 1. How often are microstents mispositioned? 2. What effect does microstent positioning have on intraocular pressure after surgery? Participants will have a one-time clinic visit for an eye exam and Optical Coherence Tomography (OCT) . From the eye exam and OCT, Researchers will assess and categorize the position of the microstents and assess the Schlemm's canal dilation. Researchers will review the participants' medical records to acquire 2-year data for the following: 1. Surgeon type and level of experience (resident, fellow, attending ophthalmologist) 2. Proportions of proper gonioscopic placement intraoperatively for each surgeon group 3. Effectiveness of surgery, based on change in intraocular pressure (IOP) from baseline medicated IOP, number of IOP-lowering medications the patient was able to discontinue, and rate of need for additional glaucoma surgery.
