In this clinical video, Drs. Rajeev Muni, Wei Wei Lee and Aditya Bansal present the in vivo assessment of retinal reattachment in humans using swept-source OCT. They characterize retinal reattachment into 5 stages. In the first stage, there's an approximation of the retina towards the retinal pigment epithelium (RPE). In stage 2, there is improvement in the cystoid macular edema and outer retinal corrugations. In stage 3, the retina makes contact with the RPE. At stage 4, there's deturgescence of the photoreceptors. In stage 5, recovery of the photoreceptors begins with the external limiting membrane, followed by the ellipsoid zone, the interdigitation zone and finally, the foveal bulge. An arrest in stage 2 can lead to an outer retinal fold, and a subretinal fluid bleb can lead to delayed progression to stage 3.
