Fig. 1. The relationship between ELM status and atrophy progression.

BAF images disclose evident shrinkage of the partially preserved retinal islet over the follow-up (A, B). The baseline structural OCT evaluation visually shows that the retinal region undergoing atrophy progression is characterized by a thinner and less reflective ELM, with respect to the central portion of the partially preserved retinal islet (C, D). Structural OCT of healthy control is provided in (E) for comparison.
