The presence of clustered hyperreflective foci (HF) at the foveola. HF are clustered where no retinal vessels are present within the foveal avascular zone. These HF are crowded around the border of the hyporeflective cavity or distributed vertically from the inner retina to the ELM. (A) Clustered HF can be found without a hyporeflective cavity. (B) A small inner retinal hyporeflective cavity is located within the lower half of the foveal slope, and HF are present just below the cavity. (C) Clustered HF are visible around the hyporeflective cavity, but the increased reflective foci appear like a retinal haze, which can be seen when retinal atrophy or fibrosis progresses. (D) The presence and path of clustered HF are more clearly visible at black on white mode. (E) Cluster HF present around the hyporeflective cavity with a dispersed pattern into the outer nuclear at temporal parafovea. (F) An inner retinal hyporeflective cavity enlarged to more than half of the foveolar thickness and clustered HF present at the border of the hyporeflective cavity.
