玻璃体黄斑牵引综合征的手术疗效

  目的  分析玻璃体切除术治疗玻璃体黄斑牵引综合征的疗效。  方法  回顾性分析2008年1月至2012年12月经频域相干光断层扫描检查确诊并接受玻璃体切除术治疗的22例(22只眼)玻璃体黄斑牵引综合征患者的临床资料。患者术后平均随访8个月(1~51个月), 观察手术前后最佳矫正视力和黄斑中心凹视网膜厚度的变化情况。  结果  22只眼中有12只眼(54.5%)为视力明显改善, 6只眼(27.3%)为视力轻微改善; 3只眼(13.6%)为视力不变; 1只眼(4.5%)为视力下降。其中视力达到0.3及以上者所占比例由术前的13.6%增加至术后的59.1%。术前黄斑中心凹视网膜平均厚度为(545±175)μm, 术后平均厚度为(220±105)μm, 术后黄斑中心凹视网膜平均厚度较术前明显减少(P < 0.01)。  结论  玻璃体切除手术是治疗玻璃体黄斑牵引综合征的有效方法。

Clinical Efficacy of Vitrectomy on Vitreomacular Traction Syndrome

  Objective  To observe the clinical efficacy of vitrectomy on vitreomacular traction syndrome.  Methods  The clinical data of 22 evaluable eyes of 22 patients with vitreomacular traction syndrome who were diagnosed by spectral-domain optical coherence tomography (SD-OCT) and underwent vitrectomy from January 2008 to December 2012 were retrospectively analyzed. Patients were followed up for an average of 8 months(1-51 months), and the changes of best corrected visual acuity (BCVA) and retinal thickness of macular fovea were recorded.  Results  After the treatment, BCVA improved significantly in 12 eyes (54.5%), improved mildly in 6 eyes (27.3%), stabilized in 3 eyes (13.6%), and decreased in 1 eye (4.5%). The proportion of patients with BCVA ≥ 0.3 increased from 13.6% before operation to 59.1% after operation. The mean retinal thicknesses of macular fovea were(545±175)μm preoperatively and (220±105) μm postoperatively, respectively (P < 0.01).  Conclusion  Vitrectomy is an effective way to improve vision and decrease macular edema in patients with vitreomacular traction syndrome.
