简介：资料患者女性,25岁。因反复咽痛伴咽异物感1月余,于2013年9月3日在我院门诊行电子鼻咽喉镜检查,提示鼻咽后壁溃疡,附有黄绿色假膜,软腭鼻咽面可见浅表点状溃疡,并附有薄层黄白色假膜（图1）,舌根、会厌舌面左侧水肿。无耳鸣及听力下降,无鼻塞、痰血、涕血、咳嗽、胸痛、潮热、盗汗等,无颈淋巴结肿大。

简介：患者，男57岁因左眼内侧渐起赘片十年余于2006年9月23日就诊我院。眼部检查：两眼视力0．8，左眼鼻侧球结膜呈翼状增厚，浸入角巩缘内4mm，头部较宽，附着部角膜灰白色混浊，

简介：目的：总结抗结核药物所致的视神经炎临床特点,探讨防治对策。方法：回顾性分析广州市胸科医院2003-01/2013-01门诊和病房患者在抗结核治疗过程中出现药物性视神经炎的临床特点。结果：抗结核药物治疗引起的药物性视神经炎不多见（17/60000）,以球后视神经炎多见,引起视神经炎的抗结核药物主要是乙胺丁醇,其次是异烟肼、链霉素。明确诊断后及时停用与视神经炎相关的结核药,并根据病情给予补充维生素,扩张血管,激素等治疗,患者的视力都有不同程度的提高。结论：在使用抗结核药期间要注意患者视力变化情况出现突发视力下降应作眼科检查,并及时给予干预,防止失明的严重后果。
