Researchers validated shorter self-efficacy scales for glaucoma medication adherence and eye drop technique. These 10-item and 6-item scales accurately identify patients needing adherence or technique education.

This study found visually impaired glaucoma and retina patients struggle significantly with eye drop instillation, often missing the eye or contaminating bottles. This highlights a critical need for improved delivery systems.

Poor glaucoma medication adherence and low adherence self-efficacy were linked to worse visual field defects, while eye drop technique was not. Clinicians should focus on improving patient adherence.

Visually impaired glaucoma patients struggle with eyedrop instillation; only 39% successfully applied one drop without touching the eye, highlighting poor technique, potential contamination, and medication waste, impacting treatment efficacy and cost.

This study found 60% of glaucoma patients reported medication problems, with memory issues and other concerns significantly linked to lower adherence. Clinicians should address these problems to improve treatment success.

Adding a second glaucoma medication significantly decreased adherence to the initial drug (longer refill intervals), potentially compromising IOP control. Clinicians should consider this impact.
