Visual Stimulus and Eye Movement
An observational study of Healthy, run by National Eye Institute (NEI) at 1 site in United States.
Trial summary
This study is designed to understand how we see visual patterns and how these patterns lead to eye movements. Normal volunteers participating in this study face a screen on which spots or patterns of light are projected. They are asked to respond to the patterns by voice, eye movements or hand movements.

About this study
Official title: Visual Motor Coordination in Man
This study is designed to understand how we see visual patterns and how these patterns lead to eye movements.
Normal volunteers participating in this study face a screen on which spots or patterns of light are projected. They are asked to respond to the patterns by voice, eye movements or hand movements. Eye and lid movements are recorded in one of the following ways:
Read more
- Electro-oculogram < small disc electrodes taped to the skin near each eye measure the eye movements as the eyes change position.
- Infrared detector < an infrared beam is reflected off the eye and picked up by detectors that record the eye movements.
- Contact lens ring < a smooth plastic ring is placed on the white of the eye surrounding the cornea and eye position is measured using a magnetic coil.
Study sessions last less than four hours.
Read the detailed description
The purpose of this protocol is to study the physiology of the visuo-motor system in normal humans. This will be accomplished by recording eye movements and other responses (such as reaction time to bar press or verbal responses) to differing stimuli. The stimuli will be primarily visual but may include auditory or tactile stimuli.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00001172, which also lists 3 linked publications.
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 Jul 2017.
