Mechanism of Retinal Reattachment Following Pneumatic Retinopexy

This video demonstrates the mechanism of subretinal fluid reabsorption without retinal displacement following pneumatic retinopexy with a steam-rolling maneuver. The small gas bubble in the vitreous cavity exerts minimum buoyant force on the retina, and therefore, there is less forceful flow of subretinal fluid under the retina, allowing the retinal pigment epithelium pump to reabsorb the subretinal fluid and the photoreceptors to interdigitate into a more natural position.
