Although visual field defects occur commonly from optic disc drusen, reduction in visual acuity is rare. We describe four patients with reduced visual acuity and one with visual field constriction to the point of legal blindness that resulted from optic disc drusen. The acute episodic and stepwise nature of visual loss in some of the cases in our series suggests a vascular mechanism. Reduced visual acuity from drusen remains a diagnosis of exclusion. It should be considered, however, when visual loss has been acute and nonprogressive or stepwise in a nerve fiber bundle distribution and when visual acuity is not reduced until visual field constriction is severe.
虽然视盘玻璃疣常导致视野缺损，但视力下降却很少见。我们描述了4例视力下降的患者以及1例因视盘玻璃疣导致视野缩窄至法定盲的患者。我们系列病例中部分病例视力丧失的急性发作和逐步进展的性质提示存在血管机制。玻璃疣导致的视力下降仍是一种排除性诊断。然而，当视力丧失为急性、非进行性或呈神经纤维束分布逐步进展，且直到视野严重缩窄时视力才下降时，应考虑这一诊断。
