Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical study is to collect standard data for the medical device neos™.

neos™ is a system that shows images and measures the resulting eye movements and pupil size.

Collecting standard data involves three steps. First it is checked if neos™ eye-tracking works well. Eye-tracking means recording where a person is looking. After that it is checked if participants look at the images shown in neos™ as planned. Finally the eye movements and the pupil size are measured. This is done in healthy volunteers including children and persons with eye and brain problems.

Participants in the study will wear a virtual reality headset. The screens in the headset will show different images. Cameras in the headset will record eye movements and pupil size. This will take about 15 minutes. During these 15 minutes the investigator looks at the following behaviors of the participants eyes:

* Where are the eyes looking
* How do the pupils react to light and darkness
* How do the eyes move
* How much can the participant see from the corner of their eyes
* How well are the eyes working together

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a post-market clinical investigation with the overall objective to collect normative data for neos™, including confirming the performance of the neos™ eye-tracking and the adequacy of the neos™visual stimuli.

This clinical investigation also has an exploratory component, looking at the presence of biomarkers in the neos™ examination results.

neos™ is a reusable medical device, that presents visual stimuli to both eyes individually, and measures the resulting eye movements and pupillary changes of each eye.

neos™ is indicated to quantitatively measure:

* The visual field
* Ocular alignment
* Afferent pupillary function
* Efferent pupillary function
* Smooth pursuit (eye movements)
* Saccades (eye movements)
* Gaze holding
* Fusional amplitude

Participants will be recruited within three groups (including children, adolescents and adults):

* Healthy volunteers, meaning no known ophthalmological, neurological or vestibular disease
* Patients with ophthalmological diseases (e.g. strabismus, cataract, macular degeneration, central artery syndrome)
* Patients with neurological diseases (e.g. Small-Vessel White-Matter Disease, cerebellar ataxia, stroke, downbeat-nystagmus, vascular dementia, multiple sclerosis, M. Parkinson, M. Niemann-Pick type C, M. Alzheimer, galactosemia, schizophrenia, etc).

The approximate duration of the single study visit is 25 minutes, not taking the time for patient information and informed consent into account. A follow up period of 15 days exists for the collection of biomarkers recorded in the participant's health record.

The direct clinical benefit from participating in this clinical investigation is the additional information provided by the neos™ examination.
