The confluence of soft drusen can lead to the formation of drusenoid pigment epithelial detachment (PED).

hard drusen can coalesce into confluent plaques associated with atrophy of the RPE and photoreceptors, leading to geographic atrophy (GA).
Large or confluent drusen are also associated with an increased risk of choroidal neovascularization, the hallmark of exudative (wet) AMD.

They vary considerably in appearance, location, and size, ranging from 30 to 50 μm in diameter or larger when confluent.
Confluent drusen form from the aggregation of hard or soft drusen. In advanced stages of age-related macular degeneration (AMD).

However, this method is only practical for focal assessments. To capture regional properties of the EZ, categorical grading schemes have been developed, particularly for describing EZ band disruption at the fovea in certain retinal conditions.

A basic measure of EZ integrity involves a subjective assessment of whether the band is intact, disrupted, or absent. This assessment can be aided by longitudinal reflectivity profiles, which evaluate the gray value intensity axially through the OCT image.
