title: Microbubble retention and failed macular hole surgery.
abstract: This case reports a possible new cause of failed macular hole surgery. Standard macular hole surgery with removal of epiretinal membranes, 16% C3F8, and strict postoperative prone positioning was performed on a patient with stage 4 macular hole. Macular hole surgery failed with retention of a microbubble of C3F8 within the macular hole during the follow-up period. Retention of a microbubble within a macular hole may prevent closure of the hole and be a previously unrecognized cause of failed macular hole surgery.
