The goal of this observational study is to learn whether personality traits are related to eye side effects from glaucoma medications in adults who currently use or previously used these medications.

The main questions this study aims to answer are:

Are certain personality traits associated with the occurrence or severity of eye side effects from glaucoma medications? Do personality traits differ between people who experience these side effects and those who do not?

Participants will complete a questionnaire that measures five personality traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism. They will also provide basic demographic information. The researchers will review participants' medical records to collect information about their glaucoma medications and any related eye side effects, including the type and frequency of side effects and whether treatment was changed because of them.

Participation involves one session lasting approximately 30 minutes. Questionnaires may be completed securely online or in person at the clinic. The study will include approximately 352 adults. No treatment will be assigned or changed as part of this study.
