CEI Van Outreach Screening Study

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The primary goal of the trial is to show that optical coherence tomography (OCT) technology can be used to effectively screen for diseases of the eye including glaucoma, macular diseases and keratoconus. Glaucoma is a disease that causes permanent vision loss and is usually accompanied by increased eye pressure. Macular diseases affect sharp, central vision. Keratoconus is a disease that affects the cornea (clear surface covering the colored part of the eye).

Condition Intervention
Macular Disease
Device: OCT imaging, the FDA Cleared iVue

Study Type: Observational
Study Design: Time Perspective: Prospective
Official Title: Prospective Evaluation of Optical Coherence Tomography Usage in the Screening of Eye Diseases

Primary Outcome Measures:
  • OCT screening efficacy for detection of early stage eye diseases in comparison to the current standard of care methods [ Time Frame: 1 year ]
    The primary goal of the trial is to show that OCT technology, specifically the FDA cleared iVue, can be used to effectively screen for glaucoma, macular diseases and keratoconus. The rate of detection of these diseases detected using OCT will be compared to the rate of detection by the physician's exam.

Estimated Enrollment: 200
Study Start Date: January 2012
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: OCT imaging, the FDA Cleared iVue
    The OCT system scans a beam of light across the eye to take a picture. OCT imaging does not touch the eye. This is a test that is performed using an FDA approved system, and is regularly used to take pictures of the back of the eye.
Detailed Description:
The identification of many eye diseases would significantly benefit from earlier detection than is available with typical eye exams. Optical coherence tomography (OCT) is an imaging technology that can perform non-contact cross-sectional imaging of tissue structure in real time. It is similar to ultrasound B-mode imaging, except that OCT measures the intensity of reflected light rather than sound waves.
