摘要

本篇報告回顧性地分析了28位接受經由額骨開顱手術切除腦下垂體難染腺體瘤病人的手術前視野及手術中所見腫瘤之位置；視野有兩眼顳側半盲的佔89%，單眼鼻側半盲的佔3.6%，兩眼鼻側半盲的佔3.6%，視野正常無缺損的佔3.6%，其視野缺損的型態與腫瘤壓迫視覺徑路的位置均能相配合。

Although there were a total of 68 cases of pituitary chromophobe adenoma who had received complete ophthalmological examination including visual field prior to surgical removal, only 28 cases underwent trasfronta1 osteoplastic craniotomy with removal of the tumor with detailed surgical description of the location of the tumor in the operation note. We analysed retrospectively the correlation between the preoperative visual field defects and the exact location of the tumors.
The preoperative visual field showed bitempora hemianopsia in 89% of cases, binasal hemianopsia in 3.6%, monocular nasal hernianopsia in 3.6% and normal visual field in 3.6% (Table 1).
The location of tumor could be classified as to its direction of growth on the basis of the surgical description, the type of involvement of the visual pathways, or the changes in the sellar region demonstrable by roentgenography (Table 2).
The whole patterns of field defect were compatible with the location of tumor which involved the visual pathway.
