Compressive optic neuropathy is an urgent condition that may lead to blindness. We report a rare case of compressive optic neuropathy secondary to lymphoma of the extraocular muscles in which the vision was successfully rescued. A 67-year-old man presented with visual acuity of hand motion in the right eye for 1 month. Magnetic resonance imaging demonstrated enlargement of the medial and inferior rectus muscles with their tendons. Tendon enlargement, which is uncommon as Graves' orbitopathy, motivated us to perform a biopsy. Intravenous steroids following biopsy and chemotherapy after definitive diagnosis allowed for recovery of vision. Clinicians should be aware that enlarged extraocular muscles due to lymphoma can cause compressive optic neuropathy.
压迫性视神经病变是一种可能导致失明的急症。我们报告了一例罕见的因眼外肌淋巴瘤继发的压迫性视神经病变，其视力成功得到挽救。一名67岁男性，右眼视力为手动，持续1个月。磁共振成像显示内直肌和下直肌及其肌腱增粗。肌腱增粗在格雷夫斯眼病中并不常见，这促使我们进行活检。活检后静脉注射类固醇以及确诊后进行化疗使视力得以恢复。临床医生应意识到，淋巴瘤导致的眼外肌增粗可引起压迫性视神经病变。
