Myelinated nerve fibers (MNF) are characterized as whitish, relatively sharply demarcated, feather-like structures located in the retinal nerve fiber layer. MNF are located quite frequently in contiguity with the optic nerve head. This may lead to a diagnostic dilemma by preventing clear visualization of the optic disc margins. We herein describe the utility of multicolor imaging (MCI) in identifying optic disc anatomy in a case of MNF contiguous to the disc. MCI and infrared reflectance were superior to color fundus photography in delineating disc margins. Our pilot study describes the efficacy of MCI in delineating optic disc anatomy in a case of MNF.
有髓神经纤维(MNF)的特征是呈乳白色,相对界限分明,呈羽毛状结构,位于视网膜神经纤维层。MNF 常与视神经头紧密相邻,这可能会导致诊断上的困难,因为这会妨碍对视盘边缘的清晰观察。我们在此描述了多色成像(MCI)在识别与视盘相邻的 MNF 中的视盘解剖结构的应用。MCI 和红外反射在描绘视盘边缘方面优于眼底彩色照相。我们的初步研究描述了 MCI 在描绘 MNF 病例中视盘解剖结构的功效。
