目的:探讨累及黄斑区的孔源性视网膜脱离行巩膜扣带术和玻璃体切割术黄斑下积液的发生率及对术后视力的影响。方法:将31例31眼孔源性视网膜脱离患者分为两组,A组15例15眼行巩膜扣带术,B组16例16眼行玻璃体切割术。术后1,3,6mo行视力、眼底及OCT检查。结果:术后1mo间接眼底镜检查所有患眼视网膜复位,矫正视力B组好于A组。术后3,6mo两组间无明显差异。OCT检查术后1mo两组黄斑下积液的发生率,差异有显著性。随时间延长,A组黄斑下积液逐渐消失。结论:巩膜扣带术后常见黄斑下积液,两组远期术后视力无明显差异。

AIM:To investigate the incidence of submacular fluid and best-corrected visual acuity(BCVA) after vitrectomy or buckle surgery for macula-off rhegmatogenous retinal detachment.METHODS:Thirty-one patients(31 eyes) with rhegmatogenous retinal detachment were devided into 2 groups,group A(15 patients,15 eyes) and group B(16 patients,16 eyes).Patients in group A were treated with scleral buckling.Patients in group B were treated with vitrectomy.Patients were examined BCVA as well as optical coherence tomography(OCT) at 1 month,3 and 6 months after surgery with indirect ophthalmoscopy.RESULTS:Indirect ophthalmoscopy indicated that all retinal detachments were reattached at 1 month postoperatively.The BCVA of group B was better than group A at 1 month after surgery,and there was no significant statistical difference between two groups at 3 and 6 months after sugery.Postoperative OCT examination at 1 month showed the incidence of submacular fluid was statistically different between two groups.The submacular fluid was gradually absorbed in group A during the follow-up.CONCLUSION:Submacular fluid often occurs after scleral buckling surgery,but the BCVA of two groups was not different during the long-term follow-up.
