Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This observational study will enroll adults with open angle glaucoma (OAG) who had surgery to reduce intraocular pressure (IOP) using the CycloPen Micro-Interventional System. Consenting participants will be followed for 24 months after their surgery.

Data regarding IOP, use of glaucoma medications, and any side effects related to the surgery will be collected from participants' preoperative examination, their surgery, and postoperative examinations.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, observational registry of eligible adults with open angle glaucoma (OAG) in whom IOP-lowering surgery with the CycloPen Micro-Interventional System was performed are consecutively enrolled.

Data will be collected from the preoperative visit(s) that directly preceded surgery, the surgical procedure, and postoperative visits through 24 months after CycloPen System use.

Specific data to be collected includes details of the CycloPen surgical procedure, IOP, use of ocular hypotensive medications, and any side effects related to the surgery.
