Quality of life for people with glaucoma

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with open- or closed-angle glaucoma (primary or secondary) complete several validated questionnaires—GQL-15, Glaucoma Symptom Scale, NEI Visual Function Questionnaire, and Ocular Surface Disease Index—at baseline and again 3–6 months after initiating medical treatment or undergoing surgery. The protocol is observational and follows real-world care rather than assigning interventions. Data are collected at the University of Iowa Department of Ophthalmology & Visual Sciences and compared between baseline and follow-up time points. The goal is to characterize how different glaucoma treatments affect patient-reported vision-related quality of life over time.
