To report a case of a full-thickness macular hole caused by Terson syndrome.

A 49-year-old man presented to our clinic with decreased visual acuity in the right eye after a subarachnoid hemorrhage due to spontaneous rupture a middle cerebral artery aneurysm. On the first examination, the corrected visual acuity was hand movement in the right eye and 1.0 in the left eye. There was massive vitreous hemorrhage in the right eye. In the left eye, there was no abnormal ocular finding. He was diagnosed with vitreous hemorrhage due to Terson syndrome and waited for the spontaneous absorption of the vitreous hemorrhage. Six months later, the vitreous hemorrhage was considerably absorbed, but a macular hole was observed. OCT scans showed a full-thickness macular hole with an epiretinal membrane.
