Abstract

Computer diagnosis of the vascular diseases treatable by laser burning (photocoagulation) are investigated. Specific concern is with identification of the region and its distance from the center of the foveal avascular zone. The parametrization of the lesion boundary and location and measurement of distance from the lesion to foveal center is accomplished with an algorithm which builds the boundary as points on spokes emanating from a chosen interior point one point on each spoke.
