摘要
目的评价光学相干断层扫描(OCT)和海德堡断层扫描(HRT-Ⅱ)对背景期糖尿病视网膜病变患者黄斑水肿的诊断价值。方法40例背景期糖尿病视网膜病变患者(80眼)分成黄斑水肿组和非黄斑水肿组,用OCT测量黄斑区厚度,HRT-Ⅱ测量黄斑水肿指数,对结果进行统计学分析。结果对背景期糖尿病视网膜病变患者黄斑水肿的诊断,OCT检查的Kappa值高于HRT-Ⅱ。以眼底荧光血管造影(FFA)检查作为黄斑水肿的诊断标准,OCT检查P=0.0001,HRT-Ⅱ检查P=0.0856。结论OCT和HRT-Ⅱ均可用于定量检测糖尿病黄斑水肿,但OCT检查对黄斑水肿的确诊比HRT-Ⅱ检查更有优势;HRT-Ⅱ对黄斑水肿的误诊率高但漏诊率低,可以作为对糖尿病视网膜病变患者黄斑水肿进行筛查的手段。
Objective To assess the value of Heidelberg retina tomograph-Ⅱ （HRT-Ⅱ ） and optical coherence tomography （OCT） on making a diagnosis of macular edema in patients with background diabetic retinopathy. Methods Eighty eyes of 40 patients with background diabetic retinopathy were divided into the macular edema group and non-macular edema group according to examination of fluorescein fundus angiography （FFA）. Macular thickness was measured by OCT and edema index was invested by HRT-Ⅱ. The results were analyzed by statistics test. Results The Kappa value of OCT examination on diagnosis for macular edema of background diabetic retinopathy was bigger than the HRT-Ⅱ. Making FFA as the diagnosis standard of macular edema, OCT examination showed P = 0. 0001,HRT-Ⅱ examination showed P = 0.0856. Conclusion OCT and HRT-Ⅱ can be used to quantitate the macular edema of the diabetic retinopathy patients. OCT is better in the final diagnosis for macular edema than HRT-Ⅱ , and HRT-Ⅱ has higher misdiagnosis rate and lower missed diagnosis rate. HRT-Ⅱ can be used to screen macular edema patients with diabetic retinopathy.
