摘要 目的:应用光学相干断层扫描(OCT)观察激光光凝治疗糖尿病黄斑水肿前后后极部视网膜厚度的变化,评价OCT在黄斑水肿治疗随访中的价值。方法:格栅样光凝治疗的患者24例(32眼)于治疗前和治疗后3个月行OCT检查,测量以黄斑中心凹为中心至4mm范围内视网膜厚度。结果:黄斑中心凹到2.2mm圆内激光治疗前及3个月术后视网膜神经上皮层厚度分别为635.6~400.6μm和378.2~180.6μm,两者比较有显著性差异(P<0.05);激光治疗前及3个月后黄斑中心凹到2.2~3.45mm视网膜神经上皮层厚度分别为459.1~229.2μm和447.2~155.4μm,两者比较无显著差异性(P>0.05)。结论:治疗3个月后黄斑区视网膜厚度降低,并且越接近黄斑中心凹处,降低作用越明显;OCT在黄斑水肿激光光凝治疗的随访观察中可发挥重要作用。
