Overview
The objective of this study is to evaluate the safety and effectiveness of Direct Selective Laser Trabeculoplasty (DSLT) in ethnic Chinese participants with Primary Open Angle Glaucoma (POAG), Ocular Hypertension (OHT), or Normal Tension Glaucoma (NTG).
Description
After informed consent is obtained, potential study participants will undergo a hypotensive medication washout period as applicable. Patients will then be re-assessed for eligibility and treated with DSLT if they meet the inclusion/exclusion criteria. The first 5 patients will be treated 360 degrees with laser energy of 1.2 millijoule (mJ) (Group 1). If all 5 Group 1 patients pass the pre-defined safety endpoint at Week 1, then the next 40 patients will be treated 360 degrees with laser energy of 1.8 mJ (Group 2). Patients will attend one treatment visit and up to 9 follow-up visits, remotely or at the clinic. Individual duration of participation is approximately 12 months.
