Optic atrophy is a clinical term used to describe an optic disc thought to be paler than normal. Optic atrophy is not a diagnosis but an ophthalmoscopic sign. Evidence of visual loss (acuity, color vision, peripheral vision) should be present. Most optic atrophy is diffuse and nonspecific, but historical and examination clues exist that help differentiate the many causes of optic atrophy. Patients with unexplained optic atrophy should be evaluated with magnetic resonance imaging.
视神经萎缩是一个临床术语，用于描述视盘比正常苍白。视神经萎缩不是一种诊断，而是一种眼底征象。应该存在视力损失（视力、色觉、周边视力）的证据。大多数视神经萎缩是弥漫性和非特异性的，但存在一些病史和检查线索，可以帮助区分视神经萎缩的许多原因。对于原因不明的视神经萎缩患者，应进行磁共振成像评估。
