Retinal detachment surgery primarily refers to the treatment of rhegmatogenous retinal detachment. There are two methods of treatment: one is external surgery, also known as scleral buckling. This involves using a compressive object to indent the sclera to support the choroid, and then employing cryotherapy to create a sterile adhesion between the choroid and the retina, thus treating the retinal detachment. Another method is internal surgery, also known as vitreoretinal surgery. This procedure involves making three incisions in the flat part of the sclera, removing the vitreous from the inside, flattening the retina with heavy water, and using a laser to create a sterile adhesion between the retina and the choroid. Currently, the surgical treatment for retinal detachment consists of these two approaches: internal and external surgeries.
