　　[摘要] 目的 分析应用OCT对孔源性视网膜脱离术前及术后黄斑区变化与视力预后的关系。 方法 选取原发性孔源性视网膜脱离并累及黄斑患者63例，在显微镜下经过巩膜外加压联合或不联合环扎术后网膜复位，分别在术后1周、1个月、3个月和12个月检测最佳矫正视力及OCT检测网膜修复情况，并进行统计学分析。 结果 术后1周视力提高情况与术前相比较，差异有高度统计学意义（χ2=10.864，P<0.01）。有11.1%的患者黄斑视网膜下液完全吸收，差异有高度统计学意义（t=5.103，P<0.01）；术后1个月视力情况与术后1周比较，差异无统计学意义（χ2=2.741，P>0.05）。术后1个月有12.8%的患者黄斑视网膜下液完全吸收，差异有高度统计学意义（χ2=4.893，P<0.01）；术后3个月视力提高情况与术后1个月比较，差异有统计学意义（χ2=6.962，P<0.05）。术后3个月有17.5%患者黄斑区视网膜下液吸收，差异有统计学意义（t=5.174，P<0.05）；术后12个月视力情况与术后3个月情况比较，差异有统计学意义（χ2=7.146，P<0.05）。术后12个月有93.7%患者黄斑区视网膜下液吸收，差异有统计学意义（t=2.946，P<0.05）。 结论 OCT可以客观的反映视网膜脱离术后黄斑区形态变化情况，并对病情的评判提供帮助。

　　[Abstract] Objective To analyze macular region changes before and after retinal detachment surgery using optical coherence tomography and their relationship with the vision. Methods Sixty-three patients with uncomplicated rhegmatogenous retinal detachment involved in macula undergoing retinal reattachment surgery were collected. Detection best corrected visual acuity and epiretinal implant by OCT at 1 week， 1 month， 3 months and 12 months， and were analyzed by statistical analysis. Results One week compared with the preoperative， postoperative visual acuity improvement difference was statistically significant（χ2=10.864， P<0.01）. 11.1% of patients with macular subretinal fluid completely absorbed， was statistically difference（t=5.103， P<0.01）； Compared with postoperative 1 week， 1 month after vision was no statistically significant difference（χ2=2.741，P>2.741）， after 1 month， 12.8% of patients with macular subretinal fluid completely absorbed， was statistically difference（t=4.893， P<0.01）； After three months compared with 1 month following surgery， vision improvement difference was statistically significant（χ2=6.962，P<0.05）. 17.5% of patients in the macular area after 3 month subretinal fluid absorption， statistically significant（t=5.174，P<0.05）； After 12 months compared with the postoperative 3 months， eyesight situation difference was statistically significant（χ2=7.146，P<0.05）. 93.7% of patients in the macular area in December after the subretinal fluid absorption， was statistically difference （t=2.946，P<0.05）. Conclusion OCT can objectively reflect the retinal detachment of postoperative changes in the macular area form， and provide help for condition evaluation.
