What is the FAF result in CHRPE testing?

Explanation:
Fundus autofluorescence imaging reflects the lipofuscin content in the retinal pigment epithelium. Congenital hypertrophy of the RPE creates a densely pigmented patch that blocks the autofluorescence signal. Because of this pigmentation, the affected area appears darker than the surrounding retina, producing a negative FAF result. So the expected FAF finding in CHRPE is hypoautofluorescence (negative). This dark patch helps distinguish CHRPE from other pigmented lesions, which may show different autofluorescence patterns.
