Disciform scars

The appearance of disciform scars in FAF imaging depends on their duration and evolution^(34,36).

Disciform scars may show different variations and alterations of FAF signal.

A decreased signal is typically observed in scarred and fibrotic areas.

It has been reported that approximately 50% of the disciform scars may be surrounded by a rim of increased FAF^(34,36).

These areas of increased autofluorescence correspond to irregularly pigmented areas and may have been caused by a multilayered RPE, a well illustrated finding in histopathology (Fig. 19 and 20)⁽³⁵⁾.
