Using a special device to lower eye pressure in glaucoma patients

Efficacy of the Nanodropper Device on Intraocular Pressure in Patients With Glaucoma

Not applicable Interventional University of California, San Francisco · NCT05273385

This study is testing a special device called the Nanodropper to see if it can lower eye pressure just as well as regular eye drops for people with glaucoma.

What this trial studies

This study aims to evaluate the effectiveness of the Nanodropper device in reducing intraocular pressure (IOP) in patients with glaucoma compared to standard eye drops. Participants aged 18 and older with stable open-angle glaucoma or ocular hypertension will be randomly assigned to use either the Nanodropper or standard eye drops. The primary goal is to demonstrate that the Nanodropper is non-inferior in lowering IOP. Follow-up assessments will occur at one month and three months after treatment initiation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with stable open-angle glaucoma or ocular hypertension who are currently using prostaglandin analogue eye drops.

Not a fit: Patients with uncontrolled glaucoma, recent eye surgery, or those using non-prostaglandin IOP-lowering medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective and potentially easier method for glaucoma patients to manage their condition.

How similar studies have performed: Previous studies have shown that smaller eye drops can be as effective as larger ones, suggesting potential success for this novel approach.
