The goal of this observational study is to evaluate the long-term safety and efficacy of a modified suprachoroidal silicone tube (SST) shunt in treating patients with primary open-angle glaucoma (POAG) and pseudo-exfoliative glaucoma (PXG).
The main questions it aims to answer are:
Does the SST shunt maintain intraocular pressure (IOP) reduction over an extended follow-up period? What is the effect of the SST shunt on endothelial cell count (ECC) and overall corneal health?
Participants will:
Undergo intraocular pressure (IOP) measurements Have their endothelial cell count (ECC) evaluated Complete assessments of best corrected visual acuity (BCVA) Be assessed for C/D ratio Be monitored for adverse events or shunt-related complications over time
Previously were treated with Suprachoroidal silicone tube shunt
Willing and able to participate in this cross sectional observational follow up
Participant capable of giving informed consent
Condition that could impact the ability of the participant to attend a follow-up visit as per the discretion of the investigator
