  • Abstract
  • Look Inside

We applied computerized image processing to fluorescein angiograms of early diabetic retinopathy using IMAGEnet by Topcon. The processing showed, frequently, dot hyperfluorescen-ce which we named possible MA. Comparison of the processed images with routine angiograms ena-bled a better identification of true microaneurysms (MAs). The present procedure also enabled detec-tion of MAs in unclear angiograms. It allowed detection of localized abnormalities in retinal capil-laries or pre-MA status. Some granular back-ground hyperfluorescence was occasionally mis-taken for MAs.
