Patterns of Glaucoma Medication Adherence over Four Years of Follow-Up.

ABSTRACT:

Purpose

To assess longer-term patterns of glaucoma medication adherence and identify whether patterns established during the first year of medication use persist during 3 subsequent years of follow-up.

Design

Retrospective, longitudinal cohort analysis.

Participants

Beneficiaries aged ≥40 years who were enrolled in a United States (US)-managed care plan for ≥7 years between 2001 and 2012 and newly diagnosed and treated for open-angle glaucoma.

Methods
