Disciform scars

Disciform scars form the stage of exudative AMD in which the retinal tissue is replaced by scar tissue (usually vascular). Disciform scars develop with regression of subretinal hemorrhages and retinal edema and hyperplasic elements of the RPE. Disciform scars are usually dry and show marked destruction of all retinal layers. It is less common to find diffuse exudation with elevation of the entire sensory retina at the posterior pole (Figure 12).
