目的评价应用海德堡视网膜地形图分析仪(Heidelbergretinatomograph,HRT)检测糖尿病黄斑水肿的可行性。方法对14只正常[和14只黄斑水肿(diabeticmacularedema,DME)[分别检测[底图像,获得以黄斑中心凹为中心,半径为0.5mm、1.0mm和1.5mm区域内的e值,每只[检查3次。结果正常组半径0.5mm、1.0mm和1.5mm三个区域内每三次检查标准差与平均e值的大小并无相关性(P>0.05);DME组,半径0.5mm区域内标准差与平均e值的大小无显著相关性(P=0.06),但半径1.0mm和1.5mm区域,标准差与平均e值的大小呈正相关(P值分别为0.02和0.007)。正常和DME两组间平均e值、合并标准差和95%可信区间差异都有显著性,DME组明显大于正常组(P<0.05),两组内检测半径变化对结果无显著影响。结论HRT对于观察随访糖尿病黄斑水肿的病情发展将会有十分重要的意义。
Objective To evaluate the feasibility of using Heidelberg retinal topography (HRT) to detect diabetic macular edema. METHODS: Fourteen normal and 14 diabetic macular edema (DME) were examined [bottom images to obtain e values centered on the fovea with radii of 0.5 mm, 1.0 mm, and 1.5 mm, respectively, and each [ Check 3 times. Results There was no correlation between the standard deviation of every three examinations and the average value of e in three groups of 0.5mm, 1.0mm and 1.5mm radius (P> 0.05). In DME group, (P = 0.06). However, for the 1.0mm and 1.5mm radius, the standard deviation was positively correlated with the mean e value (P = 0.02 and 0.007, respectively). The average evalue, standard deviation and 95% confidence intervals of normal and DME groups were significant, and the DME group was significantly larger than the normal group (P <0.05). There was no significant difference between the two groups in the detection radius. Conclusion HRT will be very important for observing the progression of diabetic macular edema.
