Minimal amount of air bag pressure and external cryocoagulation of retina for the treatment of retinal detachment

Abstract

Objective To observe the efficacy of minimal amount of air bag pressure and external cryocoagulation of retina for the treatment of retinal detachment. Methods The data of 34 eyes of 34 cases with rhegmatogenous detachment of retina were collected and analyzed retrospectively .They underwent minimal amount of air bag pressure combined with external cryocoagulation of retina.The retinal reattachment, corrected visual acuity and complications were observed after surgery.The follow-up period was 5-12 months. Results In 34 eyes, retinal reattachment was found in 31 eyes( 91.18%), poor retinal reattachment in 3 eyes, included irregular crack hole of 1 eye and pseudophakic of 2 eyes.Among 3 eyes, 2 eyes underwent scleral buckling operation and 1 eye underwent vitrectomy combined with C3F8 tamponade.The omissive retinal tear caused the first surgrey faliure was found during the second surgery. Among 31 eyes of retinal reattachment, retinal detachment recurred in 3 eyes 1 month after surgery, 2 eyes were horse-shoe holes located in the upper quadrant, 1 eye was pseudophakic.Among them, 1 eye underwent scleral buckling operation, 2 eyes underwent vitrectomy combined with silicone oil tamponade after retinal reattachment. At the last follow-up, retinal reattachment were in 32 eyes, corrected visual acuity improved 5-10 lines in 23 eyes (67.65%), improved 3- 4 lines in 8 eyes (23.53%), and 3 eyes without significant changes (8.82%). No serious complication occurred. Conclusion Minimal amount of air bag pressure and external cryocozgulation of retina for the treatment of rhegmatogenous retina detachment is safe and effective, with short time of operation, small incision and less pain to the patients, rapid recovery after operation and keeping more field for other operations.
