Study Population

19 glaucoma patients and 21 age-matched controls will be identified and consented.

Description

  • 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.
