摘要

视交叉功能障碍通常产生双颞偏视视野缺陷。视交叉功能障碍通常是由外源性病变压迫引起的，如垂体大腺瘤和脑膜瘤。在本章中，我们首先描述各种双颞偏视视野缺陷，这些缺陷可能与视交叉功能障碍一起发生。我们接下来列出视交叉功能障碍的潜在原因。然后我们回顾垂体卒中的临床特点和评估，这是由于梗死(或出血)的垂体大腺瘤。最后，我们讨论垂体卒中的处理，包括手术减压的指征和时机，并回顾影响视力恢复预后的因素。

Chiasmal Syndromes

Dysfunction of the optic chiasm typically produces bitemporal hemianopic visual field defects. Optic chiasmal dysfunction most often results from compression by extrinsic lesions, such as pituitary macroadenomas and meningiomas. In this chapter, we begin by describing the various bitemporal hemianopic visual field defects that can occur with optic chiasmal dysfunction. We next list potential causes of optic chiasmal dysfunction. We then review the clinical features and evaluation of pituitary apoplexy, which results from infarction of (or hemorrhage into) a pituitary macroadenoma. Lastly, we discuss the management of pituitary apoplexy, including the indications for and timing of surgical decompression, and review factors that affect the prognosis for visual recovery.
