Retinal Fold

A 38-year-old man underwent vitrectomy in the left eye due to a giant tear in the upper retina. SF6 gas was used as endotamponade. During the post-surgical check-up, it was identified that the patient developed a full-thickness retinal fold due to retinal slippage during fluid-air exchange. As the fold was away from the macular area, it was decided to observe the patient. Three weeks after the surgery, his best-corrected visual acuity was 20/30.
