Two Trabecular Micro-bypass Stents & Postoperative Travoprost to Treat Glaucoma Subjects on Two Hypotensive Agents

2016-08-23 12:23:22 | BioPortfolio


The study objective was to evaluate the intraocular pressure (IOP) lowering effect of two iStent devices in eyes of subjects with primary open-angle glaucoma, washed out of two anti-glaucoma medications (one a Prostaglandin) prior to stent implantation.


The study design is as follows:

- Prospective, single-arm study.

- Subjects with open-angle glaucoma and medicated IOP > 18 mmHg and ≤ 30 mmHg.

- Subjects on two topical ocular hypotensive medications (one a prostaglandin).

- Implantation of two iStent inject devices (if IOP is < 6 mmHg, at any point during the postoperative follow-up, medication will not be prescribed or will be discontinued).

- IOP will be measured by two (2) observers to minimize bias; observer 1 will look through the slit lamp and turn the dial with readings being masked, and observer 2 will document the IOP.

- Follow-up through 60 months postoperative (or up to 61 months if subject needs to undergo terminal washout).

- Descriptive statistics will be tabulated.

- Medical therapy considered necessary for the subject's welfare can be implemented at any time during the study at the investigator's discretion.
