Assessing Neurovisual Function in Patients With Cognitive Impairment

Assessing Neurovisual Function in Patients With Cognitive Impairment

The aim of this study is to measure fitness to drive in patients with a visual and a cognitive impairment. To do so, Ocusweep is used in patients with glaucoma and Mild Cognitive Impairment. The participants will be divided over four groups; patients with glaucoma, patients with cognitive impairment, patients with both and a healthy control group. Differences in performance on Ocusweep in the four different groups of participants are expected. These effects may be related to fitness to drive, which is why those results will be compared to traditional neuropsychological measures of fitness to drive. the hypothesis of the current study is that the Ocusweep performance is related to performance on other measures of fitness to drive.

• Be at least 65 years old
