a A fundus photograph of a 73-year-old woman with a large MH in the right eye. b The minimal MH diameter is 463 microns. The preoperative logMAR BCVA is 1.6; the patient had symptoms for 16 weeks. c A fundus photograph obtained 6 months postoperatively in which the free-flap technique was performed. The MH is closed. d Spectral-domain OCT shows foveal loss of the outer segments (external limiting membrane, inner segment/outer segment junction, and RPE) and hence the presence of reverse shadowing. The final visual acuity is 1.0
