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.

Detailed Description:

You are being asked to participate in this research study because you have glaucoma, which is the second leading cause of blindness in the world and accounts for 15% of blindness worldwide. Vision loss caused by glaucoma can significantly worsen your health-related quality of life. Despite the fact that glaucoma has such a big impact on a large number of people, research examining the long-term effects of glaucoma-related vision loss on one's quality of life is scarce.

The purpose of this study is to look at the long-term effect of this condition on your quality of life so that we may gain valuable information about what factors influence the quality of life of people with glaucoma. To participate in this study, you will need to allow us to perform clinical tests on your eyes, to self-report your well-being and health-related quality of life, and to let us know how well you perform your daily life activities.


Ages Eligible for Study:   18 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Subjects for this study will be recruited from the William A. and Anna V. Goldberg Glaucoma Service and Glaucoma Research Center at Wills Eye Institute in Philadelphia, PA.


Inclusion Criteria:

  • Minimum 2-year diagnosis of primary open-angle glaucoma, chronic primary angle-closure glaucoma or exfoliation glaucoma
  • Disk Damage Likelihood Scale stages 5 through 8 with visual field loss
  • Age between 21 and 80 years
  • Able to understand and speak English

Exclusion Criteria:

  • Unlikely to be available for annual ocular examination and reassessment across a 4-year period
  • Neurological or musculoskeletal problems that would influence performance on activities of daily living
  • Cognitively impaired, as assessed by a face-to-face Mini-Mental State Examination
  • Incisional eye surgery within the past three months
  • Laser therapy within the previous month
  • Any cause for visual reduction other than glaucoma
  • Any medical condition which in the investigator's opinion would preclude the subject from providing reliable and valid data
