We report two patients with optic disc drusen who suffered sudden, concentric constriction of the visual field. Visual acuity remained normal. The involved discs showed no swelling, hemorrhage, or other evidence of anterior ischemic optic neuropathy. We are unable to explain the mechanism or the pattern of visual field loss in these unusual cases.
我们报告了两名患有视盘玻璃疣的患者，他们出现了突然的、向心性视野缩窄。视力保持正常。受累视盘未显示肿胀、出血或其他前部缺血性视神经病变的迹象。在这些不寻常的病例中，我们无法解释视野缺损的机制或模式。
