OCT scan shows thinning of hyperreflective external band, corresponding to attenuation of RPE/Bruch’s complex, and deeper hyperreflectivity because of loss of outer layers including photoreceptors (Fig. 4)^(39,40).

In high resolution OCT the atrophic area shows hyperreflective clumps at different levels, segmented plaques of the outer band and elevations with variable reflectivity⁽⁴¹⁾.

In the perilesional area there are elevations of the outer retinal layers, as well as thickening of outer hyperreflective band.

At the junction area the outer band shows different degrees of loss⁽⁴¹⁾.
