Retinal detachment needs to be treated surgically, and there are two main types of surgical treatment as follows: i. Extra-scleral pad pressure surgery, which is mainly used for patients with a single, clear and relatively small retinal detachment. Vitrectomy is mainly used for patients with secondary retinal detachment, retinal detachment with a wide range, a large number of fissures or unclear fissures, which is a major operation in ophthalmology, costly and difficult to operate. Therefore, when retinal detachment occurs, you should go to a regular ophthalmic medical institution for examination in time to determine the scope of retinal detachment, the number of fissures, location and size, and choose a different surgical plan to avoid delaying the disease.
