Nanodropper Use in Primary Open-Angle Glaucoma Patients: A Non-Inferiority Trial

This study tests whether using a Nanodropper — a small device that fits on an eye drop bottle to reduce the size of each drop — works just as well as standard-sized eye drops for controlling eye pressure in people with primary open-angle glaucoma or ocular hypertension. Smaller drops reduce waste and may cause fewer side effects. **You may be eligible if...** - You are 18 or older - You have primary open-angle glaucoma or elevated eye pressure (ocular hypertension) - Your disease has been stable for at least the past year with no worsening of pressure, optic nerve, or vision - You are on no more than 2 eye pressure-lowering medications **You may NOT be eligible if...** - You have a different type of glaucoma (such as angle-closure or other secondary types) - Your glaucoma has been getting worse recently - You have had glaucoma surgery or laser treatment in the past 6 months - You require more than 2 glaucoma medications Talk to your doctor to see if this trial is right for you.
