Screening for Studies on Nystagmus and Strabismus
NCT00001861 · View on ClinicalTrials.gov ↗
Study Summary
This screening protocol is designed to help recruitment patients for National Eye Institute (NEI) studies on nystagmus and strabismus. Patients must meet specific requirements of a research study, and this protocol serves as a first step for admitting patients to an appropriate program. Candidates will undergo a medical history, physical examination, eye examination and blood test. The eye examination includes measurement of eye pressure and dilation of the pupils to fully examine the lens, vitreous and retina. Specialized tests will be done only if needed to determine eligibility for a nystagmus or strabismus study. These include routine laboratory tests, non-invasive imaging, questionnaires, and other standard tests. If needed, a test called oculography may be done to record eye movements. There are two procedures for recording and documenting these movements. In the infrared system, the patient wears a pair of glasses or goggles and looks at a red light while the head is kept steady. In the search coil system, the eye is numbed with anesthetic eye drops and a soft contact lens is placed on the eye. Then the patient looks at a red light while the head is held still. Each oculography session lasts 20 to 30 minutes. Photographs of the eye may be taken. When the screening is completed, patients will be informed of their options to participate in a study. Patients who are ineligible for a current study will be informed of alternative treatments or options. No treatment is offered under this protocol.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001861
The ClinicalTrials.gov registry entry for NCT00001861 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 1,500 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 2 conditions, with Strabismus 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: NCT00001861 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. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
