This study examines a treatment for people with chronic open-angle glaucoma (a condition where fluid builds up in the eye causing pressure) or ocular hypertension (high pressure in the eye). To join, you must be 18 or older and have the conditions in both eyes. You'll be given eye drops and will need to stop any current eye pressure medication for a few days to weeks before starting. The study compares two treatments to see which works better and checks for any side effects (unexpected problems that may happen). Visits are at 2 weeks and 6 weeks to measure eye pressure changes.

• Study lasts about 6 weeks with specific visits at 2 and 6 weeks.
• Participants must stop current eye pressure medications temporarily.
• Check if you match the requirements and do not have listed exclusions.
