  • Bleb Migration With FAX

    Mar 25 2025 by Robert Andrew Sisk, MD, FACS, FASRS

    Color stills from surgical video after subretinal delivery of gene augmentation therapy with voretigene neparvovec-rzyl A) before and B) after fluid-air exchange (FAX). The blebs were between 0.5- and 1-disc diameters from the fovea. After FAX, they gradually extended beneath the fovea and eventually merged. This spared the fovea the trauma from the injection pressure of subretinal injection while allowing treatment to the area.

  • Iatrogenic Macular Hole and Subretinal Migration of PFCL

    Feb 7 2023 by Aditya S Kelkar, MS, FRCS, FASRS,FRCOphth

    The video demonstrates a surgical scenario where the fovea gives away by the force imparted by the jet of an injecting PFCL (Perfluorocarbon heavy Liquid) and the PFCL migrates subfoveally. Intraoperative OCT confirms the presence of a macular hole. The situation is managed by ILM peeling and mobilizing subfoveal PFCL peripherally by injecting another bubble of PFCL over the posterior pole. A peripheral drainage retinotomy is then created to aspirate the subretinal PFCL followed by fluid-air exchange, PFCL-air exchange, and endolaser around the retinotomy. Post-operative OCT at 3 weeks’ follow-up shows a sealed macular hole.

  • Retinal Fold

    Sep 26 2023 by Mauricio Bayram-Suverza, MD

    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.
