摘　　要：目的观察巩膜扣带术成功的患者黄斑区视网膜下液吸收过程,分析该过程与视功能的相关性。设计前瞻性病例观察系列。研究对象孔源性视网膜脱离波及黄斑区行巩膜扣带术成功的34例35眼。方法对行巩膜外扣带手术并一次获得成功的患者进行术后3天、15天,2个月、6个月的随访。主要进行眼底检查、黄斑区OCT扫描和散瞳验光。主要指标OCT图像和最佳矫正视力。结果术后3天、15天、2个月和6个月OCT检查视网膜下液完全吸收分别为3眼(8.57%)、5眼(14.29%)、9眼(25.71%)和23眼(65.71%)。在随访期间所有眼残留视网膜下液均逐渐减少。残留视网膜下液者在持续吸收过程中,平均视力变化程度为(0.124±0.013);视网膜下液完全吸收者平均视力变化程度为0.019±0.006(t=35.26,P=0.000)。结论巩膜扣带术后视网膜平伏的患者黄斑区仍残留微量的视网膜下液,该液体缓慢的吸收可能是术后半年内患者视力仍逐步回升的主要因素。Objective By using optical coherence tomography （OCT） to observe the residual subretina fluid changes in fovea that may explain visual recovery after anatomically successful repair of rhegmatogenous retinal detachments （RD）. Design Prospective observational case series. Participants 34 patients （35 eyes） with successful retinal reattachment after macula involving RD repair. Methods 34 patients were followed up at 3 days, 15 days, 2 months and 6 months after sclera buckling. The best corrected visual acuity （BCVA）, eye fundus status were recorded. The OCT images through the center of the fovea were obtained. Main Outcome Measures The OCT images and BCVA after RD repair. Results The BCVA and OCT images were obtained 3 days to 6 months postoperatively. There were 3 eyes, 5 eyes, 9 eyes and 23 eyes respectively with residual subfovea fluid absorbed totally at 3 days, 15 days, 2 months and 6 months. In the residual subforvea fluid group, the mean visual acuity increased at 0.124±0.013. In the subfovea fluid absorbed group, the mean visual acuity increased at only 0.019±0.006. Conclusions After anatomically successful repair of RD performend with sclera buckling, the minimal residual subforvea fluid will exist for a long time and will be absorbed slowly. This may explain slow increase of postoperative visual acuity after anatomically successful repair. （Ophthalmol CHN, 2006, 15： 250-252）
