NEJM:I型糖尿病患者视网膜病变检测指导

2017-04-20 zhangfan MedSci原创

研究建立一个个性化的视网膜病变筛查时间,患者可依据当前的视网膜病变状态和糖化血红蛋白水平制定眼检查的频率

目前业界认为对于患I型糖尿病5年以上的患者,应每年进行糖尿病视力检测以及时发现并治疗潜在的增生性视网膜病变和黄斑水肿。但一份长达30年的糖尿病控制与并发症试验(DCCT)以及糖尿病干预与并发症的流行病学(EDIC)研究认为视网膜检测的频率因依据患者情况每6个月到4年间进行。

研究人员从DCCT和EDIC研究中获得视网膜照片以确定合理的视网膜病变筛查频率。马尔可夫模型被用来确定增殖性糖尿病视网膜病变或临床上显着的黄斑水肿的患者不同的初始视网膜病变水平(无视网膜病变或轻度,中度或重度非增殖性糖尿病视网膜病变)发生进展的可能性。该模型包括公认的视网膜病变进展危险因素。

研究发现,对于每4年进行筛查的无视网膜病变、每3年进行筛查的轻度视网膜病变、每6个月进行筛查的中度视网膜病变以及每3个月进行筛查重度非增殖性糖尿病视网膜病变患者,总的增生性糖尿病视网膜病变及临床显着黄斑水肿进展的可能性小于5%。进展的风险也与平均糖化血红蛋白水平密切相关。糖化血红蛋白水平为6%的患者,5年的无视网膜病变到增生性糖尿病视网膜病变或临床显着黄斑水肿的进展风险为1.0%,而糖化血红蛋白水平为10%的患者,3年的无视网膜病变到增生性糖尿病视网膜病变或临床显着黄斑水肿的进展风险为4.3%。若依据这一研究结果重新制定眼科检查频率将比年度常规检查减少58%,从而节约大量的成本。

根据这一研究结果可建立一个个性化的视网膜病变筛查时间,患者可依据当前的视网膜病变状态和糖化血红蛋白水平制定眼检查的频率,既节约了成本也不延误临床疾病的诊断
