Subretinal surgery is a procedure used to treat conditions affecting the retina, including macular degeneration or retinal detachment, by accessing the subretinal space—the area between the retina and the underlying retinal pigment epithelium (RPE).

The surgery typically involves making a small incision in the retina to remove abnormal tissue, blood, or scar tissue that has developed beneath the retina. This can help reattach the retina or remove debris that is impairing vision. The procedure is most often performed when other treatments, like laser therapy, are not effective.

Subretinal surgery is effective for restoring vision and improving the function of the retina. While it carries some risks, such as retinal tears or infection, it can be highly beneficial for patients with complex retinal conditions that require more advanced intervention.
