Study Summary
Hypothesis 1: Self-reported health-related quality of life decreases as vision impairment worsens in subjects with glaucoma. Hypothesis 2: Changes in health-related quality of life are associated with changes in clinical measures of vision and performance-based measures of visual function.
Primary Outcome
National Eye Institute Visual Function-25 questionnaire (NEI VFQ-25) is a measurement of patients perception of their visually related quality of life. Patients select answers from multiple choice lists of responses. Values are re-coded and converted to a scale of 0 to 100 where 0 is extreme difficulty and 100 is no difficulty at all (or best quality of life). Data from visits 2 through 5.
Interventions
- OTHER Clinical evaluation
- OTHER Performance based measures
- OTHER Subjective measures of vision-related quality of life
