We aim to report an unusual case of myelinated retinal nerve fibers (MRNFs) at fovea. A 39-year-old woman presented with visual impairment and her visual acuity was 20/80 in the right eye. Ophthalmologic examination revealed MRNF lesions at inferior and superior poles of optic disc in the right eye. Furthermore, a ring-shaped MRNF lesion with feathery edges was observed at fovea. MRNF lesions are rarely seen at macula, and to our knowledge, this is the first report of an MRNF lesion at fovea.
我们旨在报告一例黄斑区有髓鞘视网膜神经纤维（MRNFs）的罕见病例。一名39岁女性因视力障碍就诊，右眼视力为20/80。眼科检查发现右眼视盘上下极有MRNF病变。此外，在黄斑区观察到一个边缘呈羽毛状的环形MRNF病变。黄斑区的MRNF病变很少见，据我们所知，这是首例关于黄斑区MRNF病变的报告。
