What position should I maintain after retinal detachment surgery? Why do some patients need to crawl after surgery and some do not? Retinal detachment often requires different positions after surgery due to the different surgical methods used and the intraoperative injection of gas or silicone oil to apply pressure to the retina in some patients. 1. Extra-scleral pad compression (or ring ligation). No special postoperative position needs to be emphasized, and the head is usually tilted to the side of the fissure as much as possible. 2. Extra-scleral pad compression (or ring ligation) with intraoperative injection of sterile air. It is often necessary to maintain the prone or lateral position for 1 to 2 days after surgery. 3.Extra-scleral pad compression (or ring ligation) with intraoperative or postoperative injection of long-acting gas (C3F8). The postoperative period requires a downward-facing position or prone position for 12 to 16 hours a day for at least about two weeks, and avoid supine position in January. 4. Vitrectomy (without filler or sterile air). No special postoperative position needs to be emphasized. 5.Vitrectomy with long-acting gas (C3F8) injection. Postoperative prone or downward facing position is required for 12 to 16 hours per day, with strict prone position for at least about two weeks and avoiding supine position for one month. 6.Vitrectomy, silicone oil injection. After surgery, it is necessary to adopt prone or downward-facing position for about 1 to 3 months, and avoid supine position until silicone oil is removed. If there is blood accumulation in the anterior chamber after surgery, the position can be adjusted appropriately.
