Be older than 18 years old
Must not have
Other forms of secondary glaucoma

Summary
This trial will compare the effects of adding netarsudil or brimonidine to the eye drops of patients with glaucoma who are already using latanoprost. The study will measure changes
Who is the study for?
This trial is for patients with Normal Tension Glaucoma (NTG) who are already using latanoprost. Participants should be stable on their current treatment and available for a screening visit and at least one follow-up. Specific inclusion or exclusion criteria were not provided.
What is being tested?
The study compares the effect of adding netarsudil versus brimonidine to NTG patients' existing latanoprost regimen on intraocular pressure (IOP). It's a randomized, multicenter trial where participants won't know which additional medication they're receiving.
What are the potential side effects?
Possible side effects of netarsudil include eye redness, cornea deposits, and allergy symptoms. Brimonidine may cause dry mouth, fatigue, or allergic reactions. Side effects can vary based on individual patient response.
