  • Abstract
  • Look Inside

We applied computerized image processing to fluorescein angiograms of age-related macular degeneration (ARMD) to achieve contrast enhance-ment. The series comprised 69 eyes with drusen: 44 with neovascular type ARMD and 25 with ARMD without choroidal neovascularization.

Enhance effect was more pronounced in hard drusen. The processing made smaller drusen observ-able. Image quality of large-sized soft drusen im-proved by far lesser degree. In some eyes, image enhancement showed numerous spotty or granular hyperfluorescences over a wide fundus area, sugges-ting the presence of diffuse lesions in the retinal pigment epithelium. Some large-sized soft drusen showed to contain hyperfluorescent dots by enhan-cement. Our image-processing procedure were thus useful in detailed clinical classification of age -related drusen
