Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Glaucoma is the second leading cause of visual impairment worldwide. Eye drop medications reduce vision loss from glaucoma by at least 60%, but eye drops must be taken every day to be effective. However, adherence to eye drop treatment is poor with only 50% of patients regularly taking their prescribed eye drops. The investigators are developing the Devers Drop Device (D3) eye drop monitor to accurately measure eye drop cap removal and to improve eye drop-taking behavior. The investigators will test eye drop adherence with the D3 device in a randomized, prospective clinical trial.
