Visual Stimulus and Eye Movement
NCT00001172 · View on ClinicalTrials.gov ↗
Study 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. Eye and lid movements are recorded in one of the following ways: 1. Electro-oculogram \< small disc electrodes taped to the skin near each eye measure the eye movements as the eyes change position. 2. Infrared detector \< an infrared beam is reflected off the eye and picked up by detectors that record the eye movements. 3. 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001172
The ClinicalTrials.gov registry entry for NCT00001172 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 225 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Eye Institute (NEI), which has 214 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Healthy appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00001172 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
