A 360-degree peripapillary hyper-reflective ovoid mass-like structure (PHOMS)

Published:September 28, 2020DOI:
      A 31-year-old woman developed papilledema from idiopathic intracranial hypertension. Enhanced-depth imaging optical coherence tomography (EDI-OCT) excluded optic disc drusen (ODD) but was notable for a peripapillary hyper-reflective ovoid mass-like structure (PHOMS), contiguous 360 degrees around the optic disc, forming a 3-dimensional torus (i.e., donut) (Fig.) Radial sections through the right optic nerve head are shown in the left column; a PHOMS is seen at each of the twelve clock-hours of the peripapillary region in the middle column and duplicated and shaded yellow in the right column.
