Objective To study the optical coherence tomography to assess the diagnostic value of macular degeneration in patients with diabetic retinopathy. Methods 40 cases of diabetes mellitus in our hospital patients with macular lesion as observation group, the other of the same period of 40 healthy people as control group cases, compared two groups of patients with optical coherence tomography results, as well as the observation group of patients using fluorescein fundus angiography diagnosis, compare the two group patients diagnosis. Results The macular center concavity healthy crowd to average (219.23±8.16 mu m, for patients with diabetic macular lesion is (312.26±140.15) microns, observation group is significantly higher than control group (P<0.05). And fluorescein fundus angiography combined with optical coherence tomography method in the diagnosis of CME has great difference. Conclusion Compared with fluorescein fundus angiography, using optical coherence tomography method can make more accurate diagnosis for the patients with disease.%目的：研究光学相干断层扫描对糖尿病视网膜病变患者黄斑病变的诊断价值。方法：选择我院收治的40例糖尿病视网膜黄斑病变患者作为观察组，另选取同一时期的健康人群40例作为对照组，对比两组患者光学相干断层扫描结果，同时对观察组患者使用荧光素眼底血管造影法进行诊断，将观察组患者两种诊断结果进行对比。结果：健康人群的黄斑中心凹度平均为（219.23±8.16）μm，而糖尿病视网膜黄斑病变患者则为（312.26±140.15）μm，观察组明显高于对照组（P<0.05）。另外荧光素眼底血管造影以及光学相干断层扫描法在诊断合并CME时具有较大的差异。结论：相比于荧光素眼底血管造影法，使用光学相干断层扫描法能够对患者疾病进行更为准确的诊断。
