This report describes a case of vitreopapillary traction with right inferior altitudinal defect similar to anterior ischemic optic neuropathy. A 35-year-old man with inferior altitudinal defect in his right eye was referred. The right optic disc was elevated and the superior disc margin was blurred. Spectral domain optical coherence tomography (SD-OCT) of the right optic disc showed the vitreous cortex was highly reflective and pulling the optic disc margin superiorly. The posterior hyaloid membrane on the nasal side of the optic disc was less reflective than that superior to the disc, suggesting that vitreopapillary traction contributed to this condition. During a careful 12-month observation, no change was noted in the optic disc appearance or visual field. Thus, SD-OCT was useful in visualizing the posterior hyaloid membrane and was helpful in the diagnosis of vitreopapillary traction syndrome.
本报告描述了一例伴有右下象限缺损的玻璃体视乳头牵引病例,类似于前部缺血性视神经病变。一名右眼有下象限缺损的35岁男性前来就诊。右侧视盘隆起,视盘上缘模糊。右侧视盘的光谱域光学相干断层扫描(SD-OCT)显示玻璃体皮质反射性高,向上牵拉视盘边缘。视盘鼻侧的后玻璃体膜反射性低于视盘上方的后玻璃体膜,提示玻璃体视乳头牵引导致了这种情况。在为期12个月的仔细观察期间,视盘外观和视野均未发现变化。因此,SD-OCT有助于观察后玻璃体膜,对玻璃体视乳头牵引综合征的诊断有帮助。
