Rhizotaxy: A Surgical Procedure for Retinal Conditions

Rhizotaxy is a surgical procedure used to treat various conditions affecting the retina, such as retinal detachment, macular hole, and epiretinal membrane. The word "rhizotaxy" comes from the Greek words "rhizo," meaning "root," and "taxis," meaning "arrangement."

In rhizotaxy, the surgeon makes small incisions in the sclera (the white part of the eye) to access the retina. Using a specialized instrument called a cryoprobe or a laser probe, the surgeon applies heat or cold energy to specific areas of the retina to create a pattern of scars that will help to reattach the retina to the underlying tissue. This process is called "photocoagulation" or "cryotherapy."

The goal of rhizotaxy is to restore the normal anatomy and function of the retina, which can improve vision and prevent further complications such as blindness. The procedure is usually performed under local anesthesia, and patients may need to stay overnight in the hospital for observation after the surgery.
