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 To investigate the visual function of patients with idiopathic macular hole surgery. Methods 19 patients (19 eyes) with idiopathic macular hole patients, including 2 eyes of 3 eyes, 3 eyes of 10 eyes and 4 eyes of 6 eyes. Vitreoretinal surgery for macular hole. Visual acuity of international standard, laser retina visual acuity, apparent acuity response (ERG) and Humphrey 30-2 visual fields were measured preoperatively and postoperatively. Results 1 International standard visual acuity: preoperative visual acuity 0. 0 1 to 0 .1, postoperative visual acuity 0. 0 4 to 0. 4, visual acuity before and after surgery showed no significant difference (P> 0.05) . 2 Laser Retinal Vision: preoperative laser retina visual acuity 0.12 to 0.4, postoperative laser retina visual acuity from 0.2 to 0.6. There was a significant difference in the changes of visual acuity between preoperative and postoperative laser retina (P <0.05). 3 ERG intensity response curve: preoperative and postoperative b-wave maximum amplitude Rmax (μV) and the slope of the representative of the n-value of the change was no significant difference (P> 0.05). The log  logarithmic L og value of half - intensity optical stimulation K (cd · sec / m2) was significantly lower than that before operation (P <0.05). 4Humphrey visual field: 0 ~ 10 ° after surgery compared with preoperative light threshold increased, the difference was significant (P <0. 05). There was no significant difference between the preoperative and postoperative 15-30 ° thresholds (P> 0.05). Conclusion Surgical treatment of IMH can improve the function of macular cone cells in the retina.
