BACKGROUND
Although visual field defects are well-known complications of optic disc drusen, reduction in visual acuity with this condition is rare.
METHOD/RESULTS: We report on a 68-year-old male with bilateral optic disc drusen who presented with monocular loss of vision in the right eye associated with an inferior altitudinal visual field defect and signs consistent with acute anterior ischaemic optic neuropathy, confirmed on fluorescein angiography. He also had a left inferior nasal step, but no evidence of glaucomatous cupping. The disc drusen were documented clinically and on B scan ultrasound and computed tomography.
CONCLUSIONS
The diagnosis of acute anterior ischaemic optic neuropathy should be considered in patients with optic disc drusen who present with reduced visual acuity, particularly when the visual loss has been acute and non-progressive and is associated with altitudinal field loss and characteristic fluorescein angiography signs.
背景
尽管视野缺损是视盘玻璃疣的常见并发症，但这种情况下视力下降却很少见。
方法/结果：我们报告了一名68岁男性，患有双侧视盘玻璃疣，右眼出现单眼视力丧失，伴有下方视野缺损，以及与急性前部缺血性视神经病变相符的体征，荧光素血管造影证实了这一点。他左眼下方鼻侧也有视野缺损，但没有青光眼性视盘凹陷的证据。视盘玻璃疣通过临床检查、B超和计算机断层扫描记录下来。
结论
对视盘玻璃疣患者出现视力下降时，应考虑急性前部缺血性视神经病变的诊断，特别是当视力丧失为急性且无进展，并伴有视野缺损和特征性荧光素血管造影表现时。
