NCT ID: NCT05971238 Recruiting - Light Sensitivity Clinical Trials

Eye Movement Behaviour and Pupil Size in Natural Outdoor and Indoor Scenes

Start date: July 1, 2023
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04251234 Terminated - Bipolar Disorder Clinical Trials

Light at Night Study

LAN
Start date: October 15, 2020
Phase: N/A
Study type: Interventional

The purpose of this mechanistic study is to examine light sensitivity (melatonin suppression) in people with bipolar depression I, and compare it to healthy controls. This is not a treatment study.

NCT ID: NCT01860534 Completed - Light Sensitivity Clinical Trials

"Eye Protection After Mydriatic Use for ROP Screening: Impact on Vitals Signs and Pain Scores"

Start date: July 2011
Phase: N/A
Study type: Interventional

Pupillary dilation induced by mydriatic agents during Retinopathy of Prematurity exams can persist for hours. Despite regular use of eye protection for mydriatic-induced light sensitivity for infants, children and adults, eye protection after mydriasis has not been addressed in neonates. This study examines the use of eye patches to protect the dilated pupil from light exposure and their impact on vital signs and pain scores. prevents tachycardia, tachypnea and discomfort in neonates after ROP screening.
