目的:探讨垂体腺瘤对眼视功能损害的临床表现。

方法:对 126 例( 252 只眼)垂体腺瘤患者进行视力、视野、荧光眼底血管造影(Fundus fuorescein angiography, FFA)、图形视诱发电位(Pattem visual evoked potential, PVEP)及眼底检査。

结果:视力下降 186 只眼,占73.8%。眼底原发性视神经萎缩 130 只眼,占51.6%。视野缺损 156 只眼,占69.6%。PVEP异常 160 只眼,占88.9%。26.2%的患者以眼部异常为首诊症状,其中16.7%曾被诊断为眼科疾病。

结论:垂体腺瘤可引起视功能的损害,充分认识垂体腺瘤在眼部的临床特点,有助于早期诊断及时治疗。

Purpose : To investigate the clinical manifestation of damage of visual function causedby pituitary adenoma.

Methods: Visual acuity, visual field, fundus fluorescein angiography (FFA), pattemvisual evoked potential (PVEP) and examination fundus were performed in 126 cases(252 eyes)of pituitary tumor.

Results :There was 73.8% (186 eyes) of patients with decreased visual acuity, 51.6%(130 eyes) with primary optic atrophy, 69.6 %(156 eyes) with the defects of visualfield and 88.9%(160 eyes) with abnormal PVEP. Abnormal ophalmological manifestationwas the first diagnostic symptom in 26.2%, and 16.7% was misdiagnosed as eye diseases.

Conclusions: Pituitary tumor could cause defection of visual function. lt is helpful toearly diagnosis and timely treatment by fully understanding clinical features in the eyewith pituitary tumor.
