To identify vitreopapillary tractional forces as a possible cause of optic nerve head elevation.
Case reports. Two patients aged 64 and 84 years underwent detailed ocular examination and B-scan ultrasonography.
Both patients had a unilateral elevated optic nerve head with normal color vision, normal pupillary responses, and full kinetic perimetry. Biomicroscopic and B-scan ultrasonographic evaluation confirmed the presence of vitreopapillary traction.
Vitreopapillary traction can cause unilateral optic nerve head elevation. The posterior hyaloid should be evaluated in patients with optic nerve head elevation.
确定玻璃体视乳头牵拉力是否为视神经乳头抬高的可能原因。
病例报告。两名年龄分别为64岁和84岁的患者接受了详细的眼部检查和B超检查。
两名患者均为单眼视神经乳头抬高，色觉正常，瞳孔反应正常，动态视野检查正常。生物显微镜检查和B超检查证实存在玻璃体视乳头牵拉。
玻璃体视乳头牵拉可导致单眼视神经乳头抬高。对视神经乳头抬高的患者应评估玻璃体后脱离情况。
