摘　　要：目的　探讨特发性黄斑裂孔手术治疗前后患者的视功能。　方法　 19例 (19只眼 )特发性黄斑裂孔患者 ,其中 2期 3只眼 ,3期 10只眼 ,4期 6只眼。采用玻璃体视网膜手术治疗黄斑裂孔。术前和术后均进行国际标准视力、激光视网膜视力、明视强度反应 ERG和 Humphrey 30 - 2程序视野测定。　结果　 1国际标准视力 :术前视力 0 .0 1至 0 .1,术后视力 0 .0 4至 0 .4,术前术后视力改变差异无显著性的意义 (P>0 .0 5 )。2激光视网膜视力 :术前激光视网膜视力 0 .12至 0 .4,术后激光视网膜视力从 0 .2至 0 .6 3。术前和术后激光视网膜视力改变差异有显著性的意义 (P<0 .0 5 )。 3 ERG明视强度反应曲线 :术前和术后 b波最大振幅 Rmax(μV)和代表曲线斜率的 n值的改变差异均无显著性的意义 (P>0 .0 5 )。术后半饱合光刺激强度K(cd· sec/ m2 )的对数单位 L og值 ,较术前降低 ,差异有显著性的意义 (P<0 .0 5 )。 4Humphrey视野 :术后0～ 10°较术前光阈值提高 ,差异有显著性的意义 (P<0 .0 5 )。术前和术后 15～ 30°光阈值差异无显著性的意义 (P>0 .0 5 )。　结论　手术治疗 IMH能提高视网膜黄斑部视锥细胞功能。Objective [WT5”BZ]To investigate the visual function of idiopathic macular hole before and after macular surgery. [WT5”HZ]Methods [WT5”BZ]Vitreous retinal surgery was performed in 19 patients(19 eyes) with idiopthic macular hole.Among them,3 eyes belonged to stage 2,10 eyes stage 3 and 6 eyes were stage 4. The visual function including international standard visual acuity,laser retinal visual acuity,photopic ERG intensity responses and Humphrey 30° 2 visual field were tested and compared before and after the surgery. [WT5”HZ]Results [WT5”BZ]①International standard visual acuity was from 0.01 to 0.1 preoperatively,and from 0.04 to 0.4 post operatively, the difference was not significant(P>0.05).②Laser retinal visual acuity was from 0.12 to 0.4 preoperatively,and from 0.2 to 0.63 postoperatively,the difference was significant (P<0.05).③In photopic ERG intensity responses:the Log K value of b wave decreased after surgery (P<0.05),but no obvious change found in Rmax and n Value after operation.(4)Humphrey visual field examination revealed the thresholds for 0 10° increased after surgery(P<0.05),but not obvious for 15 30°. [WT5”HZ]Conclusion [WT5”BZ]The visual function of the macular cones are increased by macular surgery for IMH. [WT5”HZ]
