This set of images (click the image above to enlarge) are optical coherence tomography (OCT) images of retained perfluoro-octane(PFO) droplets after repair of a complicated retinal detachment. PFO is a good surgical tool to help reattach the retina as they force sub retinal fluid out of any retinal tears and helps adhere the retina to the back of the globe. PFO also helps localize the margins of retinal detachments, and reduces the height of the retinal detachment which assists in surgical laser photocoagulation. Per Dr. Bernstein, “These subretinal droplets of PFO can remain in place indefinitely and cause minimal visual symptoms as long as they are not under or near the fovea.”
