Fundus photograph (a) and optical coherence tomography (OCT) (b) images of the medium full-thickness macular hole (FTMH) in right eye with a diameter of 399 μm, with vitreomacular traction (VMT). After 1 month (c) of intravitreal injection of expansile gas, the vitreous detachment and the anatomical closure of the hole was observed. After 2 months (d) of the surgery, a hole closure was completed and the macular fovea was almost normal. Corrected visual acuity was improved from 0.1 (pre-treatment) to 0.4 (post-treatment)
