OCT对手术治疗玻璃体黄斑牵引综合征疗效评估作用

Evaluate the efficacy of vitrectomy in vitreomacular traction syndrome by OCT

目的探讨0cT对手术治疗玻璃体黄斑牵引综合征疗效的评估作用。方法回顾性系列病例研究。收集2015年l。12月在广西壮族自治区民族医院确诊为玻璃体黄斑牵引综合征患者18例（18只眼），行玻璃体切除、黄斑前膜剥离手术，术后平均随访2个月，对比患者手术前后的最佳矫正视力，OCT检查黄斑部视网膜情况，并进行统计学分析。结果术后OCT检查所有患者黄斑部牵引解除，视网膜表面异常反光带消失，黄斑中心凹恢复接近正常状态，黄斑区视网膜水肿减轻，视网膜厚度下降。术前平均BCVA（0．18±0．09），术后2月平均BCVA（0．30±0．18），差异有统计学意义（P〈0．05）；术前黄斑部视网膜平均厚度（355±66）μm，术后2月平均厚度（306±29）μm，差异有统计学意义（P〈0．05）。经相关分析得出视力与黄斑部视网膜平均厚度呈显著负相关关系（r=-0．425，P=0．001）。结论OCT能量化评估玻璃体黄斑牵引综合征手术的治疗效果。

Objective To discuss the evaluation function by OCT on the efficacy of vitrectomy in the treatment of vitreomacular traction syndrome. Methods A retrospective analysis. The clinical data of 18 patients （18 eyes） with vitreomacular traction syndrome who were diagnosed by OCT and underwent vitrectomy from January 2015 to December 2015 were retrospectively analyzed. Pa- tients were followed up for an average of 2 months, and the changes of best corrected visual acuity （BCVA） and retinal thicknesses of macular fovea were. recorded. Results After the treatment, all pa- tients＇ traction of macular were resolved. The mean BVCA were （0.18±0.09） preoperatively and （0.30±0.18） postoperatively. The mean retinal thicknesses of macular fovea were （355±66）Bm preoper- atively and （306±29）μm postoperatively, the difference was showed significance meaning in the two groups. Conclusions OCT could be evaluate quantitatively the effect of vitrectomy in the treatment of vitreomacular traction syndrome.
