To compare the effectiveness of sustained-release dexamethasone (DEX) intravitreal implant in nonvitrectomized eyes and vitrectomized eyes with diabetic macular edema (DME).
A retrospective review of the medical records of 40 eyes of 30 consecutive patients with diabetic macular edema who underwent intravitreal DEX implant injection. Patients were divided into 2 subgroups: 31 eyes that were nonvitrectomized (group 1) and 9 eyes that had previously undergone standard pars plana vitrectomy (group 2). The main outcome measures were BCVA and foveal thickness (FT).
A significant improvement was seen in BCVA in both group 1 and group 2 at the 1st, 2nd, and 6th months after treatment with DEX implant ( < 0.05). In group 1, a significant reduction in FT was observed at the 1st, 2nd, and 6th months ( < 0.05). In group 2, a significant reduction in FT was seen at the 1st and 2nd months ( < 0.05), but the reduction rate at the 6th month after the injection was not statistically significant ( = 0.06).
DEX implant is effective for the treatment of diabetic macular edema, and the effectiveness of the drug is similar in vitrectomized and nonvitrectomized eyes.
比较缓释地塞米松(DEX)玻璃体内植入物在未行玻璃体切割术的眼和已行玻璃体切割术的糖尿病性黄斑水肿(DME)眼中的疗效。
回顾性分析30例连续接受玻璃体内DEX植入物注射的糖尿病性黄斑水肿患者的40只眼的病历。患者分为2个亚组:31只未行玻璃体切割术的眼(第1组)和9只先前已行标准平坦部玻璃体切割术的眼(第2组)。主要观察指标为最佳矫正视力(BCVA)和黄斑中心凹厚度(FT)。
在使用DEX植入物治疗后的第1、2和6个月,第1组和第2组的BCVA均有显著改善(<0.05)。在第1组中,第1、2和6个月时FT显著降低(<0.05)。在第2组中,第1和2个月时FT显著降低(<0.05),但注射后第6个月的降低率无统计学意义(=0.06)。
DEX植入物对糖尿病性黄斑水肿有效,且该药物在已行玻璃体切割术的眼和未行玻璃体切割术的眼中疗效相似。
