To evaluate the clinical characteristics of discrete margins of different retinal reflectivity (DMDRR) in ultra-widefield fundus photography.
This DMDRR comprises a discrete border, with differing patterns of reflectivity on either side. Spectral-domain optical coherence tomography was performed on both the macula and the margin. The incidences of epiretinal membrane (ERM) and peripheral retinal pathologies of patients with a DMDRR (n = 36) were compared with a control group (n = 41).
An ellipsoid zone (EZ) defect at the DMDRR was detected in 34 eyes (92.2%), and vitreous traction was detected in 20 eyes (55.6%). A significantly higher proportion of eyes in the DMDRR group had an ERM, retinal hole, and cystic retinal tuft compared with the control group ( = .022, = .010, and < .001, respectively).
The DMDRR indicates EZ disruption that may originate from vitreous traction. Meticulous observation for vitreoretinal interface diseases is mandatory for these patients. .
评估超广角眼底照相中不同视网膜反射率离散边界（DMDRR）的临床特征。
DMDRR 包括一个离散边界，两侧的反射率模式不同。对黄斑区和边缘均行频域光学相干断层扫描。将 DMDRR 患者（n=36）的视网膜前膜（ERM）和周边视网膜病变的发生率与对照组（n=41）进行比较。
在 34 只眼（92.2%）中检测到 DMDRR 的椭圆体带（EZ）缺损，在 20 只眼中检测到玻璃体牵引。与对照组相比，DMDRR 组的眼内 ERM、视网膜裂孔和囊性视网膜簇的比例显著更高（=0.022，=0.010，<0.001）。
DMDRR 表明 EZ 破坏可能源于玻璃体牵引。对于这些患者，必须仔细观察玻璃体视网膜界面疾病。
