| ［摘要］ 目的 探讨在视网膜脱离手术疗效评价中应用光学相干断层扫描(OCT)的价值。方法 对50例50眼裂孔源性视网膜脱离波及黄斑部患者进行冷凝、巩膜外垫压+环扎和放出视网膜下液手术,手术前及手术后1 w、1 M、3 M、6 M、12 M进行OCT检查，定量检测黄斑中心凹下积液高度、黄斑部视网膜神经上皮厚度。结果 随访时间为13～21（16.26±2.59）个月，平均黄斑中心凹下积液高度手术前为（735.88±532.86）μm，手术后1 w为（150.54±188.43）μm,两者差异有统计学意义（t=7.3231,P<0.05）；平均黄斑部视网膜神经上皮厚度手术前为（132.12±56.89）μm，手术后1 w为（109.18±40.93）μm,两者差异有统计学意义（t=2.3142,P<0.05）；手术后1 w间接检眼镜下视网膜复位47例（94%），OCT仅显示15例（30%）黄斑中心凹下积液高度为0，此时33例脱盲（矫正视力≥0.05）（66.0%）；手术后12 M OCT显示47例（94.0%）黄斑中心凹下积液高度为0，此时48例脱盲（96.0%）。结论 OCT能定量测量黄斑中心凹下积液高度，客观评价视网膜脱离手术后疗效,为视网膜脱离手术后的治疗提供依据。 |

| Abstract: |
| ［Abstract］ Objective To evaluate the efficacy of applying optical coherence tomography (OCT) in retinal detachment surgery.Methods The surgery was performed by using scleral buckling±cerclage on 50 eyes of 50 patients with macular-off rhegmatogenous retinal detachment. The submacular fluid height and foveal retinal thickness were measured by OCT examination before surgery and at 1 week, 1, 3, 6 and 12 months after the surgery.Results The average submacular fluid height decreased from （735.88±532.86）μm to （150.54±188.43）μm postoperatively(t=7.3231, P<0.05) with a follow-up ranged from 13 to 21(16.26±2.59)months. The averages of foveal retinal thickness were （132.12±56.89）μm and （109.18±40.93）μm respectively, before and 1 w after the operation(t=2.3142, P<0.05). Retinal reattachment was found in 47 cases(94.0%) 1 w after the surgery under ophthalmoscope examination and the submacular fluid was totally absorbed in 15 cases(30.0%). As a result, 33 cases(66.0%) got rid of blindness(the best-corrected visual acuity ≥0.05). OCT showed that no foveal fluid was found in 47 cases(94.0%) 12 months after the operation and 48 cases(96.0%) got rid of blindness.Conclusion OCT can quantitatively measure the submacular fluid height of central macular, objectively evaluate the effects of retinal detachment surgery and provide the evidences for the postoperative treatment. |
