Purpose: To report the characteristic fundus and optical coherence tomography (OCT) findings of a case of sub-internal limiting membrane (ILM) hemorrhage in a patient with premacular hemorrhage following retinal artery macroaneurysm.
Case summary: A 74-year-old female presented with sudden vision loss in her left eye three days prior. Her best corrected visual acuity was 0.1 and intraocular pressure was 11 mmHg in the left eye. Premacular hemorrhage and rupture of macroaneurysm were observed on fundus examination and characteristic yellow band around the premacular hemorrhage was observed. In OCT, hemorrhage was observed between the dome-shaped membrane and the retinal nerve fiber layer, and the yellow band observed on the fundus was observed as a thick high reflective zone of the external limiting membrane (ELM). Pars plana vitrectomy and ILM removal was performed for treatment of sub-ILM hemorrhage. After the surgery, the yellow band on the fundus and the high reflective lesion of the ELM were absent on OCT, and there was no recurrence.
Conclusions: Among patients with premacular hemorrhage, a yellow band on the fundus and a highly reflective lesion on the ELM on OCT may be helpful in diagnosing sub-ILM hemorrhage and differentiating it from subhyaloid hemorrhage.
