Neuroretinitis is relatively rare. It refers to the triad of subacute visual loss, optic disc swelling and a macular star (figure 1), often in association with cells in the vitreous.1–4 An illustrative case is presented in this issue of Practical Neurology .5 The macular star typically takes 1–2 weeks to develop, meaning that it is usually not possible to make the diagnosis when the patient first presents. At that time, the condition may resemble, and be misdiagnosed as, idiopathic demyelinating optic neuritis (IDON) with the potential for inappropriate use of multiple sclerosis disease-modifying agents or, alternatively, failure to treat a preventable cause of visual loss. It is therefore important that neurologists are aware of this condition.6 Figure 1 Macular star. Reprinted with permission from Weerasinghe and Lueck.6 The radial arrangement of the hard exudates in a macular star arises from the anatomy of the outer plexiform layer of the retina, and not all macular stars are perfectly formed.5 The combination of optic disc oedema with a macular star2 can occur in conditions other than neuroretinitis, the most frequent being hypertensive retinopathy (see table 1). Most masqueraders …

神经视网膜炎：一个棘手的模仿

神经性视网膜炎相对少见。它指的是亚急性视力丧失、视盘肿胀和黄斑部星状体（图 1）三联征，通常与玻璃体中的细胞相关。1-4 本期实用神经病学 .5 黄斑部状星体提供了一个说明性案例通常需要 1-2 周的时间才能形成，这意味着通常无法在患者首次就诊时做出诊断。那时，这种情况可能类似于并被误诊为特发性脱髓鞘性视神经炎 (IDON)，有可能不恰当地使用多发性硬化症改善剂，或者未能治疗可预防的视力丧失原因。因此，神经科医生了解这种情况很重要。6 图 1 黄斑部星形。经 Weerasinghe 和 Lueck 许可转载。6 黄斑星中硬性渗出液的放射状排列源于视网膜外丛状层的解剖结构，并不是所有的黄斑星都是完美形成的。5 视盘水肿与黄斑星的结合可能发生在其他情况下与神经性视网膜炎相比，最常见的是高血压性视网膜病变（见表 1）。大多数伪装者……
