Glaucoma Group
Age-Matched Controls

Detailed Description:
Eye movements that quickly scan a visual scene are critical to a number of daily activities including driving. It is not known whether rapid eye movement called saccades, are altered in glaucoma.

Ages Eligible for Study:   40 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
19 glaucoma patients and 21 age-matched controls will be identified and consented.

Inclusion Criteria:

  • Ages from 40-80 years. Primary open angle glaucoma is defined by characteristic glaucomatous optic nerve head findings and the presence of corresponding visual field deficits in one or both eyes. All control subjects will be age-matched, with no ocular medical or surgical history, and a completely normal eye examination. Age-matched controls will be recruited from local hospital personnel and accompanying relatives.

Exclusion criteria:

  • Any patient with a history of other eye disease, neurological disease or neurodegenerative disorder, or history of incisional ocular surgery within the previous month will be excluded.
