Abstract
PURPOSE: Understanding patients' attitudes toward novel therapeutic options can help guide providers in personalizing treatment regimens for glaucoma patients. This study aimed to determine factors associated with acceptance of new drug delivery options among glaucoma patients. METHODS: A total of 199 patient volunteers participated in an interviewer-administered survey from June to August 2016 at the Glaucoma Service of Massachusetts Eye and Ear. The questionnaire was designed to determine acceptance of 6 drug delivery approaches: (1) triple combination eye drop, (2) microdose eye spray, (3) drug-eluting contact lens, (4) drug-eluting periocular ring insert, (5) injectable subconjunctival drug insert, and (6) injectable anterior chamber implant. Other factors analyzed included self-reported demographics, disease severity, and prior ocular history. RESULTS: The average respondent age was 63.2 ± 15.1 years; 48% were female. For approaches 1-6 listed above, overall acceptance rates were, respectively, 85%, 54%, 31%, 43%, 32%, and 30%. Patients with greater disease severity and prior incisional glaucoma surgery were more likely to pursue alternatives to traditional eye drops. CONCLUSIONS: There is limited acceptance of alternatives to traditional eye drop medications among glaucoma patients. Understanding motivating factors and potential barriers to patient acceptance of novel drug delivery approaches is important in how providers will incorporate these glaucoma treatment options into practice.
