Does Glaucoma Cause Loss of Brain Function?

Status Completed

Clinical Trial Summary

The purpose of the study is to determine if glaucoma is associated with neurodegenerative changes in areas of the brain other than the occipital lobe. This will help guide the direction of further research in the use of neuroprotective agents in preventing or controlling such changes. The final goal is to improve the quality of life for patients with glaucoma.

Clinical Trial Description

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 magnetic resonance imaging (MRI) brain scans will reveal areas of cortical degeneration in glaucoma patients, and the extent of damage in these areas should correlate with patients ability to perform vision-dependent tasks, as measured by the Assessment of Ability Related to Vision (AARV).

Patients with glaucoma who were outliers in two previous studies, Assessment of Ability Related to Vision (AARV) or Assessment of Disability related to vision (ADREV), in that they had 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. ;
