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.

| Ocusweep test battery | Device | Ocusweep test battery to measure vision, visual system and cognitive performance including attention (Comparison of Ocusweep system to conventional neuropsychological test methods) (With the help of Ocusweep tests, information is obtained about the functioning of the whole visual system - from the ability of the eye to see to the efficiency of the brain to process visual information and the accuracy of eye movements) |
| Measure | Description | Time Frame |
|---|---|---|
| Perception speed | Measured by Ocusweep RTP-test | 2 years |
| Evidence of cognitive impairment measured by MoCA-test | Measured with Montreal Cognitive Assessment. Outcome measure is a score between 0 and 30. | 2 years |
| Evidence of impaired attentional ability - Cognitive profile | Measured by performing mazes. Unit of measure is seconds it takes to perform and number of errors. | 2 years |
| Evidence of impaired Executive Functioning - Cognitive profile 1/2 | Measured by the Trail Making Test. Unit of measure is seconds to perform the test, which will be converted in a percentile score. | 2 years |
