Conditions glaucoma, macular disease, keratoconus
Treatment oct imaging, the fda cleared ivue
Sponsor Oregon Health and Science University
Collaborator National Eye Institute (NEI)
Start date January 2012
End date January 2014
Trial size 200 participants
Trial identifier NCT01510392, OHSU IRB#00008034-Outreach


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).

Additional Information

Official title Prospective Evaluation of Optical Coherence Tomography Usage in the Screening of Eye Diseases
Principal investigator Michael Chiang, MD
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.
