- Have been referred to as "incipient atrophy" since they are usually preceding geographic atrophy and are more likely to develop soft drusen and choroidal neovascularization
- Areas of stippled, punctate hypopigmentation of degenerated RPE associated with pigment mottling
- Thinning of the overlying neurosensory retina
- The underlying choroidal vessels are not more readily apparent than in normal area without atrophy
- Fluorescein angiogram demonstrates diffuse hyperfluorescence with a pattern of reticular or punctate blockage in the areas of RPE degeneration corresponding to the pigment clumping.
