光学相干断层扫描对糖尿病性黄斑水肿的诊断意义

Diagnostic value of optical coherence tomography for diabetic macular edema

目的:观察黄斑水肿的光相干断层扫描(OCT)图像特征;探讨糖尿病黄斑水肿与视力、糖尿病性视网膜病变分期和糖尿病病程的关系。方法:对58例(97眼)患者通过荧光血管造影分期分组,OCT测量各组厚度后,采用SPSS10.0软件进行统计学分析,分析各型黄斑水肿构成比及其与视力、糖尿病病程、分期的关系。结果:黄斑水肿的OCT图像主要包括视网膜海绵样肿胀、黄斑囊样水肿及神经上皮浆液性脱离;随糖尿病病程延长,糖尿病视网膜病变的发展,黄斑水肿构成比逐渐增加、病变加重,黄斑区视网膜厚度有增加趋势,视功能受损程度加重。结论:糖尿病性视网膜黄斑水肿的OCT图像为临床提供类似病理学的直观资料,尤其对治疗的随诊及判定预后具有重要参考价值。

AIM： To observe the image characteristics of optical coherence tomography （OCT） performed on the patients with macular edema, and to investigate the relationship between macular edema and vision, DR staging and the course of DM. METHODS. Fifty-eight cases （97 eyes） were grouped by FFA. The deep of macular was measured by OCT, and SPSS10.0 was used to analyze the relationship between macular edema and vision, DR staging and the course of DM. RESULTS.. The OCT images of macular edema included sponge-like retinal swelling, macular cystoid edema, and serous retinal detachment, With the DM process lasting, DR and macular edema were aggravated step by step, at the same time the retina＇s deep of macular region trended to be more thicker and visual function became more serious. CONCLUSION.. OCT can display the pathologic characteristics in diabetic macular edema. It is potentially useful for the diagnosis and treatment of diabetic macular edema.
