A 20-year-old man, with known aplastic anaemia, presented with decreased vision in his left eye due to subinternal limiting membrane (sub-ILM) haemorrhage (Fig 1A). Swept-source optical coherence tomography (SS-OCT, Fig 1B) showed multiple hyperreflective foci (related to the blood cells) below the dome-shaped hyperreflective membrane (ILM) along with a faint second layer corresponding to the posterior hyaloid (red arrows). The temporal macula showed irregular depressions (blue arrows) along the surface of the retina, which are characteristic of dissociated optic nerve fiber layer (DONFL). This case supports mechanical separation of ILM from underlying retina as the main reason for DONFL appearance.
