Primary Outcome Measures

Name	Time	Method
Intraocular Pressure	12 months	Intraocular pressure measurements will be extracted from each patient's medical record at the baseline, 6 month, and 12 month follow-up visits. For all time points, a mean intraocular pressure will be calculated by averaging the intraocular pressure across both eyes. Change in intraocular pressure over the 12 month period will then be assessed by calculating the difference in mean intraocular pressure.
Glaucoma Medication Percent Adherence	12 months	Medication adherence will be measured using the number of recorded doses from the Medication Event Monitoring System (MEMS) data, divided by the number of prescribed doses. Medication adherence can range from 0% to 100%.
Glaucoma Medication Adherence Self-Efficacy Score	12 months	Medication adherence self-efficacy is measured using a 21-item scale that has a reliability of 0.89. Scores can range from 21 to 63, and a higher score indicates a better outcome.
