Finding the best glaucoma questionnaire: a qualitative and quantitative evaluation of glaucoma knowledge assessments

The goal of the study was to determine which glaucoma quiz provides the best information about patient glaucoma knowledge to clinicians in clinical practice settings. Four glaucoma quizzes were identified from the literature and national eye education programs and were qualitatively analyzed to categorize questions by topic. Quizzes were assessed by 64 glaucoma specialists using an online survey, with descriptive statistics. Comments about the quizzes were analyzed qualitatively using themes and representative quotations. Quizzes covered content that was important for glaucoma diagnosis and management. The National Eye Health Education Program (NEHEP) and Prevent Blindness America quizzes covered primarily diagnosis, screening, and risk factors, and the quizzes from the literature primarily covered causes of glaucoma, vision loss, eye drops, and systemic disease. Overall, the NEHEP quiz was ranked best for clinical practice, ranked first by 38%. Ranked second overall, the Gray quiz was ranked first by 34% and last by 34%. The NEHEP quiz was rated most useful for assessing baseline general glaucoma knowledge for a busy clinical practice. The Gray quiz appears to be more useful as part of a comprehensive education program, perhaps in combination with an ophthalmic educator.
