目的探讨蝶鞍区肿瘤对视力和55°视野的影响以及Humphrey-Ⅱ型自动视野计FF-81程序在蝶鞍区肿瘤视野检查中的准确性。方法对确诊为蝶鞍区肿瘤84例(168眼)住院病人,术前行视力、55°视野及周边视野检查(相同大小的白色视标)。结果术前视力下降者117眼(69%)。视野异常者FF-81程序55°视野133眼(79%);周边视野计检查130眼(77%)。结论蝶鞍区肿瘤常常累及视神经,从而导致患者视力下降、视野缺损,以颞侧视野缺损为多。Humphrey-Ⅱ型自动视野计FF-81程序检查的55°视野对蝶鞍区肿瘤的患者能早期发现典型以及不规则的视野改变。对蝶鞍区肿瘤的早期诊断有重要意义。
Objective To investigate the effects of tumor in the sellar region on visual acuity and 55 ° field of vision and the accuracy of the Humphrey-Ⅱ automatic fluoroscopy FF-81 program in visual field of the sella region. Methods Eighty-four patients (168 eyes) diagnosed as sella region tumor were examined with preoperative visual acuity, 55 ° visual field and peripheral visual field examination (the same size white visual target). Results Preoperative visual acuity was 117 eyes (69%). Visual field abnormalities in FF-81 program 55 ° field of vision in 133 eyes (79%); peripheral visual field examination of 130 eyes (77%). Conclusion The tumors of the sellar region often involve the optic nerve, resulting in decreased vision and visual field defects in patients with temporal visual field defects. Humphrey-Ⅱ automatic fluoroscopy FF-81 program examination of 55 ° field of vision of patients with sella region of the tumor early to detect typical and irregular changes in visual field. On the early diagnosis of sella tumors of great significance.
