About this study
Official title: Characterization of Eye Movement Behaviour and Pupil Size Through Eye-tracking in Natural Outdoor and Indoor Scenes
In this study, the researchers will be using eye tracking and detailed lighting measurements to understand how different types of indoor and outdoor lighting affect the eye movements and pupil sizes of our participants. Participants will be paired up and undergo six eye tracking sessions, split across two appointments. Each appointment will involve viewing either indoor or outdoor scenes, and before each session, participants will spend time adapting to the lighting conditions. Overall, each participant will spend 24 minutes being tracked, and the entire study will take about 2-3 hours to complete. The investigators expect differences in eye movements and pupil size between indoor and outdoor scenes.

Questions about this trial
What is this clinical trial studying?
A study testing Indoor vs. outdoor scenes in people with Light Sensitivity, run by Technical University of Munich at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 2 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Alexander Hahn (+49(0)70716011670, alexander.hahn@tuebingen.mpg.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Saccade frequency - Indoor scene 1 (time frame: Baseline). The study lists 48 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Aug 2023.
