Is this trial a fit for you?
✓Likely a good fit
Adults 18 and older with glaucoma who are currently or previously treated with glaucoma medications and able to complete surveys in English or French.
✕Probably not a fit
Patients without glaucoma medication exposure or those unable to complete questionnaires may not benefit.

What this trial studies
This observational study will enroll adults using or who have used glaucoma medications to see if personality traits relate to ocular adverse effects. Participants complete a questionnaire measuring five personality traits and provide basic demographics, while researchers review medical records for glaucoma medications and side effects. The study focuses on whether certain traits are associated with the occurrence or severity of side effects and if personality influences reporting or management of these events. No interventions are involved; data will be analyzed to identify potential associations.
Why it matters
Potential benefit: If a link is found, clinicians could tailor counseling and monitoring to individual personality profiles to improve tolerance and adherence.
How similar studies have gone: To date, there is limited evidence on personality and ocular medication side effects, making this area exploratory.
