伴近视的鞍区肿瘤眼部病变特点

Clinical analysis of the characteristics of ocular abnormalities in sellar tumor with myopia

目的 :探讨近视患者的鞍区肿瘤眼部病变的临床特点。方法 :回顾分析了 18例伴近视的鞍区肿瘤的视力、视野及眼底等情况。结果 :18例初诊时 ,19眼 (占 5 2 .8% )视力低于 4.0 ,仅 5例 (占 2 7.8% )视野缺损呈典型的视交叉性单、双颞侧偏盲 ,10例 (占 5 5 .6 % )双眼视神经不同程度萎缩 ,4例 (占 2 2 .2 % )单眼视神经萎缩。结论 :伴近视的鞍区肿瘤眼部病变常很严重 ,容易被误诊为青光眼性视神经萎缩 ,视乳头炎、缺血性视神经病变。

Objective:To analyze the characteristics of ocular abnormalities in sellar tumor with myopia.Methods:To review retrospectively the visual acuity, visual field and fundus of 18 cases of sellar tumor with myopia.Results:19 eyes(52.8%) had visual acuity <4.0D. The original diagnosis in 5 cases(27.8%) was typical coloboma with visual fields that had bitemporal or monocular temporal hemianopsia,in 10 cases(55.6%) it was bilateral optic atrophy and in 4 cases(22.2%) it was unilateral optic atrophy.Conclusion:Ocular abnormalities in sellar tumor with myopia are often very severe. It is easily misdiagnosed as optic atrophy of glaucoma,optic neuritis or ischemic optic neuropathy. Examination by CT or MRI is indicated. [FK(WB80011?6]
