Pituitary tumors are adenomas of a region of the sella turcica which can produce compression of the anterior visual pathway.
Besides clinical signs of visual improvement such as enhanced visual acuity and visual field, the use of electroophthalmological methods can help monitor patients after neurosurgery.
The N75 P100 amplitude of the p-VEP has proven to be the most sensitive marker for measuring-improvements after surgery. This amplitude significantly increased, whereas latency time, visual acuity and visual field showed no statistically significant changes after surgery.
The p-VEP is an important tool in treating patients with compression of the visual pathway.
垂体瘤是蝶鞍区的腺瘤,可对视神经前通路产生压迫。
除了视力提高和视野扩大等视力改善的临床体征外,使用眼电生理方法有助于对神经外科手术后的患者进行监测。
p-VEP的N75-P100波幅已被证明是衡量手术后改善情况最敏感的指标。该波幅显著增加,而手术后潜伏期、视力和视野无统计学显著变化。
p-VEP是治疗视觉通路受压患者的重要工具。
