title: Digital overlay of fluorescein angiograms and fundus images for treatment of subretinal neovascularization.
abstract: A system for comparing sequential fundus photographs and angiograms has been developed using a personal computer and commercially available image processing software. This process provides rapid results and a high degree of accuracy in image correlation, even when images come from different cameras with different magnifications. Though no concentrated effort was made to compare the superiority of this method to the manual technique, the value of the manual results is fully acknowledged, and this technique is offered as another method of achieving the same end. This technique can be used to determine the adequacy of treatment of subretinal neovascularization, recurrence of subretinal neovascularization in subsequent angiograms, pigment epithelial creep, and changes in fundus lesions.
