Nanodropper microdrop delivery for primary open-angle glaucoma and ocular hypertension

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

NA · 59th Medical Wing · NCT05844384

This test will see if Nanodropper microdrops of glaucoma medicines lower eye pressure as well as standard eye drops for adults with primary open-angle glaucoma or ocular hypertension.

What this trial studies

This is a randomized, single-masked, crossover non-inferiority trial comparing intraocular pressure (IOP) response to standard eyedrops versus Nanodropper-mediated microdrops in adults with primary open-angle glaucoma or ocular hypertension. Each participant will use one delivery method for three months, then cross over to the other method, with mean IOP (mm Hg) ± SEM as the primary efficacy endpoint. Secondary endpoints include safety and usability measured by patient surveys at enrollment and follow-up visits. The study enrolls patients on up to two IOP-lowering medications with stable disease and is conducted at Wilford Hall Ambulatory Surgical Center.

Who should consider this trial

Good fit: Adults (18+) with primary open-angle glaucoma or ocular hypertension who are on no more than two IOP-lowering medications and have had stable disease for at least one year.

Not a fit: Patients with other types of glaucoma, recent disease progression, use of more than two IOP medications, or recent IOP-lowering surgery (except SLT performed >6 months prior) are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, Nanodropper could let patients control eye pressure with smaller microdrops that provide similar effectiveness while reducing side effects and medication waste.

How similar studies have performed: Early pilot studies of microdrop delivery have suggested comparable IOP control and reduced ocular exposure, but large randomized non-inferiority trials are limited.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* POAG/OHTN patients above the age of 18 years.
* On a maximum of 2 IOP lowering medications.

Exclusion Criteria:

* Glaucoma not of the POAG or OHTN variety or other retinal diseases.
* Progression of disease within the preceding 1 year (IOP elevation, optic disc cupping, visual field changes).
* Using more than 2 IOP-lowering medications.
* IOP-lowering surgical interventions or lasers except for SLT. SLT may have been completed 6+ months prior to study start date.
