Researchers Create Ultra-Detailed 3-D Images of Retinas of Over 400 AMD Patients Using High Resolution OCT Machines
March 22, 2009
e! Science News reports that researchers, using optical coherence tomography (OCT) machines with a resolution two times higher than standard commercial OCT’s, have created ultra-detailed 3-D images of the retinas of 400 people suffering from different stages of macular degeneration. Each person’s eye was scanned in 180 different slices and stitched together to form a 3-D image of the eye.
For patients suffering from “dry” AMD, the ultra-high resolution OCT enables individual layers of the retina to be visualized more precisely, which allows better detection and monitoring of the build up of drusens between layers of the retina.
For patients suffering from “wet” AMD, the ultra-high resolution OCT provides a more accurate estimate of the volume of fluids leaked by abnormal blood vessels growing between layers of the retina.
The researchers are publishing their images to help advance technologies for quicker detection of the details and severity of both forms of AMD. Additionally, researchers say ultra-high resolution 3-D images of the retina could provide a faster and more efficient way for drug makers to develop and evaluate new treatments in clinical trials.
