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 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)
Conventional neuropsychological test battery to measure executive functioning, attention, visuoconstructive abilities and processing speed

Measured by Ocusweep RTP-test
Time frame: 2 years
Evidence of cognitive impairment measured by MoCA-test
Measured with Montreal Cognitive Assessment. Outcome measure is a score between 0 and 30.
Time frame: 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.
Time frame: 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.
Time frame: 2 years
Evidence of impaired Executive Functioning - Cognitive profile 2/2
Measured by the Trail Making Test. Unit of measure is errors made during the test.
Time frame: 2 years
Evidence of impaired Visuoconstructive abilities - Cognitive profile
Measured by the Benton Visual Retention Test. Unit of measure is number of correctly drawn designs (0-10)
Time frame: 2 years
Evidence of slow reaction time - Cognitive profile
Measured with Vienna Test System. Unit of measure is reaction time in ms. Results will be converted into percentile scores.
Time frame: 2 years
Evidence of impaired visual attention measured by UFOV-test - Cognitive Profile
Vision and visual attention measured with Useful Field of View. Unit of measure is milliseconds which is converted in group scores provided by UFOV.
Time frame: 2 years
Evidence of glaucomatous visual field defects 1/2
Narrowing of the visual field measured with Standard Automated Perimetry (SAP).
Time frame: 2 years
Evidence of glaucomatous visual field defects 2/2
Visual field defects measured by Ocusweep test called Reaction Time Perimetry. Outcome measure is reaction time on multiple locations on the visual field. From this data, unseen locations are calculated.
Time frame: 2 years
