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

The primary objective of this study is to compare changes in intraocular pressure (IOP) in a population of POAG and OHTN patients in response to administration of 1) standard drops of IOP lowering medications and 2) Nanodropper-mediated microdrops of IOP-lowering medications. The hypothesis is that Nanodropper-mediated microdrops of IOP-lowering medications will not result in a significant difference in IOP relative to standard drops of IOP-lowering medications after three months of daily eyedrop administration with each delivery system. The primary outcome measure for this efficacy endpoint will be mean IOP (mm Hg) ± SEM. A secondary objective of this trial is to evaluate Nanodropper's safety and usability. Surveys that have been designed to gain an understanding of the differences in side effects and usability between using Nanodropper-mediated microdrops compared to standard eyedrops will be administered to patients at the enrollment visit and at each follow-up visit.

Inclusion criteria

• POAG/OHTN patients above the age of 18 years.
• On a maximum of 2 IOP lowering medications.
• Stable disease without progression in IOP, optic disc cupping, RNFL changes, and visual field changes within the previous 1 year.

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.
