|Condition or disease|
Death of retinal ganglion cells causes loss of neurons in areas other than just the visual cortex. These neurodegenerative changes decrease the patient's ability to perform the activities of daily living. Tensor-based morphometry analysis of MRI brain scans will reveal areas of cortical degeneration in glaucoma patients, and the extent of damage in these areas will correlate with their ability to perform vision-dependent tasks, as measured by the Assessment of Ability Related to Vision (AARV).
Patients with glaucoma who were outliers in Assessment of Ability Related to Vision (AARV) Study or Assessment of Disability related to vision (ADREV) Study, in that they have poor performance-based measure scores despite having midrange visual field scores.
Mini-Mental State Exam and T-1 weighted MRI brain scan and will be performed.
