[The clinical study of the damage of visual function caused by pituitary tumor].
OBJECTIVE
To investigate the clinical manifestation of damage of visual function caused by pituitary adenoma.


METHODS
Visual acuity, visual field, fundus fluorescein angiography (FFA), pattern visual 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 visual field and 88.9% (160 eyes) with abnormal PVEP. Abnormal ophthalmological manifestation was the first diagnostic symptom in 26.2%, and 16.7% was misdiagnosed as eye diseases.


CONCLUSIONS
Pituitary tumor could cause defection of visual function. It is helpful to early diagnosis and timely treatment by fully understanding clinical features in the eye with pituitary tumor.
