Differentiating optic disc edema (ODE) from pseudo optic disc edema (PODE) continues to pose a diagnostic dilemma. Current report highlights the role of multicolor imaging (MC) in differentiating ODE from PODE. Composite multicolor images of the disc in ODE show greenish hyperreflectance that extends beyond the optic disc margins with irregular blurry margins and obscured disc vasculature whereas PODE shows a greenish hyperreflectance with clear and distinct margins and well delineated disc vasculature. MC imaging adds to the present armamentarium of imaging modalities obviating needless neurological evaluation mandatory in a case of true disc edema.
鉴别视盘水肿(ODE)和假性视盘水肿(PODE)仍然是一个诊断难题。当前报告强调了多色成像(MC)在区分ODE和PODE方面的作用。ODE中视盘的复合多色图像显示绿色高反射,其超出视盘边缘,边缘不规则模糊且视盘血管模糊不清,而PODE显示绿色高反射,边缘清晰且视盘血管清晰可辨。MC成像增加了现有的成像方式,避免了在真正的视盘水肿病例中进行不必要的神经学评估。
