Removal of Retained Subfoveal PFO

In this 1-Minute Video, Drs. Rajeev Muni and Mostafa Hanout demonstrate their method for removing a retained perfluorocarbon (PFO) bubble. A 38-gauge flexible tip macular hydrodissection cannula was connected to an automated viscous fluid infusion kit and used to create a small retinotomy approximately 700 to 800 microns inferior to the fovea, inducing macular detachment involving the retained PFO bubble. The flexible cannula was bent at its junction with the shaft and carefully advanced through the same retinotomy, enabling direct aspiration of the retained subfoveal PFO bubble. A fluid-air exchange was performed to conclude the surgery.
