OCT对视网膜脱离术前及术后黄斑区扫描情况分析

Analysis macular region changes before and after retinal detachment surgery using optical coherence tomography

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。

Objective To analyze maeular region changes before and after retinal detachment surgery using optical coherence tomography and their relationship with the vision. Methods Sixty-three patients with uncomplicated rheg-matogenous 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 improve- ment difference was statistically signifieant（x2=10.864, P〈0.01）. 11.1% of patients with maeular 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（x2=2.741 ,P〉2.741 ）, after 1 month, 12.8% of patients with macular sub- retinal 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 （X2=6.962,P〈0.05）. 17.5% of pa- tients in the macular area after 3 month subretinal fluid absorption, statistically significant（t=5.174,P〈O.05）; After 12 months compared with the postoperative 3 months, eyesight situation difference was statistically significant（x2=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 maeular area form, and provide help for condition evaluation.
