目的 探讨糖尿病视网膜病变 (diabeticretinopathy ,DR)与糖尿病黄斑病变 (diabeticmaculopa thy ,DM )之间的关系 ,以探讨DM独立分期对指导临床治疗的意义。 方法 对眼科初诊的 5 82例糖尿病患者行荧光素眼底血管造影 (fundusfluoresceinangiography ,FFA)及眼科常规检查 ,根据眼底改变将DR分为2型 6期 ,DM分为 4度。 结果 DM的严重程度随DR的逐渐加重而增加 ,但不完全平行。在无DR病例中 ,发生I度DM者占 5 .4% ;IV期DR中 ,III度DM发生率最高 ,占 5 4.4% ;Ⅴ期DR中 ,仍有未发生DM的病例 ,占 5 .1%。 结论 DR和DM之间不完全平行 ,故DM独立分期对选择黄斑区最佳治疗时机 ,保存黄斑功能有重要意义。
Objective To investigate the relationship between diabetic retinopathy (DR) and diabetic maculopathy (DM) in order to explore the clinical significance of DM independent staging. Methods The fundus fluorescein angiography (FFA) and routine ophthalmology examination were performed on 5 82 diabetic patients with newly diagnosed ophthalmology. According to the change of fundus, DR was divided into 2 types and 6 stages, and DM was divided into 4 degrees. Results The severity of DM increased with the gradual aggravation of DR, but not completely parallel. In patients without DR, I degree DM occurred in 5.4% of patients. In stage IV DR patients, the incidence of III degree DM was the highest, accounting for 54.4%. In stage Ⅴ, there were still no cases of DM, accounting for 5%. 1%. Conclusions The DR and DM are not completely parallel, so the independent staging of DM is of great significance for choosing the best timing of macular treatment and preserving macular function.
