Study Start Date: February 2008
Study Completion Date: August 2010
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts
Glaucoma Patients
Glaucoma patients covering the entire range of visual field loss from none to advanced.
Control Group
Aged matched people with no eye diseases.

Detailed Description:

This research study is designed to test the usefulness and repeatability of testing how much disability is caused by vision loss due to glaucoma. We are recruiting 100 patients with glaucoma and 20 healthy (have no eye disease) individuals to be enrolled in this study. The healthy study participants will be enrolled in order to describe how a healthy individual will perform on the test designed to assess one's performance when completing ten activities of daily living.

Clinical testing will be conducted by binocular and monocular visual fields, contrast sensitivity and visual acuity. The NEI-VFQ 15 Quality of Life Questionnaire will be used to measure patients perception of how well they are doing.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population

One hundred patients with bilateral unstable glaucoma and twenty patients who appear to be normal will be enrolled.

Criteria

Inclusion Criteria:

  • All patients 18 yrs of age and older
  • must understand and respond to spoken English and be fully literate.

Exclusion Criteria:

  • Patients with significant neurological problems (like Parkinson's disease), motor problems (like arthritis) or other significant illnesses that may prevent them from completing the testing involved in the study (like advanced heart failure).
  • Patients who have received training related to low vision.
