隐匿型间接视神经损伤的临床特点分析

目的探讨隐匿型间接视神经损伤的临床特点。方法回顾性分析2005年6月-2009年6月间,我科收治的隐匿型间接视神经损伤患者15例（18眼）的临床特点,包括主诉、外伤特点、视力变化、瞳孔及眼底改变、视野、视觉诱发电位、视觉对比敏感度等特点。结果15例患者首次就诊均因视力下降不明显及眼底检查正常而漏诊。临床特点：伤后早期视力轻度改变,有眼前亮度及色觉异常,出现相对性瞳孔传入性障碍,视觉诱发电位、视野、视觉对比敏感度异常。结论对眼部外伤特别是眉弓处外伤、伤后视力改变不明显但有亮度及色度觉改变患者,应进一步检查是否存在相对性瞳孔传入性障碍,并作视觉诱发电位、视野、视觉对比敏感度等检查以明确有无视神经的损伤,避免漏诊而延误治疗。
