Optic disc oedema describes the nonspecific, localized swelling of the optic nerve head regardless of aetiology. Therefore, differentiating among the various aetiologies depends on a thorough history and knowledge of the clinical characteristics of the underlying conditions. Papilloedema strictly refers to optic disc oedema as a consequence of elevated intracranial pressure. It is usually a bilateral condition and visual function is preserved until late. Optic disc oedema caused by an anterior optic neuropathy is usually unilateral and accompanied by the loss of visual function.
视盘水肿描述的是视神经乳头非特异性的局限性肿胀，无论其病因如何。因此，区分各种病因取决于详尽的病史以及对潜在疾病临床特征的了解。视乳头水肿严格来说是指由于颅内压升高导致的视盘水肿。它通常是双侧性的，并且在疾病晚期之前视觉功能都会得以保留。前部视神经病变引起的视盘水肿通常是单侧的，并伴有视觉功能丧失。
