About this study
To identify vision-screening tests that can accurately predict those three- and four-year old preschoolers who would benefit from a comprehensive vision examination because of signs of amblyopia, strabismus, and/or significant refractive error.
Read the detailed description
The Vision In Preschoolers (VIP) Study is a multi-center, multidisciplinary, prospective clinical study to evaluate screening tests for identifying preschool children in need of comprehensive eye examinations. The primary goal of the VIP Study is to identify an effective and efficient battery of screening tests that has high sensitivity and specificity in identifying preschoolers in need of further evaluation for amblyopia, strabismus and/or significant refractive error.
The VIP Study is designed in three-phases.
Phase I activities will establish which screening tests perform well when administered by licensed eye care professionals (pediatric optometrists and pediatric ophthalmologists) in a population of 1000 Head Start preschoolers at high risk for the targeted vision disorders.
Phase II activities will provide evaluation of the tests' performance when administered by pediatric nurses and lay people on a high risk population of 1000 Head Start preschoolers. Each child will be tested twice with each screening test - once by a pediatric nurse and once by a lay screener. Tests selected for Phase II will be determined by the outcome of Phase I.
Phase III activities will evaluate the performance of the tests in identifying individuals with specific vision disorders in a general population of (6400) Head Start preschoolers. The category of screening personnel and the specific screening tests used in Phase III will be determined by the outcome of Phases I and II.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Vision Screening in people with Amblyopia and Strabismus, run by National Eye Institute (NEI) at 5 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 16 Oct 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States. 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.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
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?
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 16 Oct 2009.
