The incidence of foraminogenic retinal detachment in China is 7.98/100,000, and its peak incidence is between the ages of 20-29 and 60-69. The incidence of foraminogenic retinal detachment due to myopia accounts for 80%, and the incidence of myopia is increasing year by year, up to 60% among high school students in China, and this figure is still growing, so foraminogenic retinal detachment is increasingly threatening the health of our people, especially the young adults. Traditional external surgery (local pressure + fluid release ± ring ligation) is the classic method for treating foraminogenic retinal detachment, with a primary repositioning rate of about 80%, but the surgery is very traumatic and takes a long time, and the total complication rate is as high as 28.3%, including intraocular hemorrhage (15.6%), choroidal leakage (8.6%), and spherical wall perforation, intraocular infection, intraocular pressure elevation, and severe photoreceptor retinal vitreous impaction. Complications (about 1%), choroidal hemorrhage accounted for 11.3%, and the rate of secondary surgery can be as high as 20%. How to improve the success rate of primary surgery, reduce complications, and improve the quality of surgery has been the concern of domestic and foreign eye surgeons. From 2005 to 2007, we were the first in China to carry out minimal amount of extra-scleral pressure to treat foraminogenic retinal detachment in 12 cases and 14 eyes with satisfactory results and a success rate of 100%, among which two cases were found to have new holes, one case had retinal flattening within 12 hours after re-pressurization, and one case had retinal flattening after observation of laser treatment. The following are three typical cases: Case 1 Retinal detachment with horseshoe-shaped fissure, 2 stitches of silicon sponge, and complete retinal flattening within 12 hours after surgery. Case 2 Round retinal fissure with 1 stitch of silicone sponge and complete retinal recovery within 12 hours. Example 3 Two adjacent circular retinal fissures with 2 stitches of silicone sponge and complete retinal flattening within 12 hours. Compared with conventional surgery, minimal extra-scleral pressure surgery has the following advantages: 1) precise localization, the pressure area is limited to the fissure, and the scope of surgery is reduced; 2) no fluid release is required; 3) recovery is rapid, and the retina is all flattened within 12 hours, and the recovery of the external eye is also rapid; 4) surgical trauma and complications are greatly reduced. The success rate was 100% and no various complications occurred. The procedure reached the level reported in international literature and is a leader in China, and the successful experience has great promotion value.
