首诊于眼科颞枕叶脑梗死患者视野改变分析

Analysis of visual field changes of the temporal and occipital lobe infarction on those first visit in the Department of Ophthalmology

目的探讨颞枕叶脑梗死患者的常见视野改变及其危险因素。方法白2000年至2006年对就诊于眼科门诊的95例经cT检查确诊为颞枕叶脑梗死的患者用Octopus自动视野计进行检查并作统计分析。结果视野改变：同侧偏盲者73例，占76．84％；同侧象限盲者13例，占13．68％；管状视野者5例，占5．26％；同侧偏盲样中心暗点者3例，占3．16％；下半盲者1例，占1．05％。患高血压病者66例，占69．47％；高血压合并糖尿病者4例，占4．21％；糖尿病者4例，占4．21％。结论颞枕叶脑梗塞患者视野改变多为同侧性视野缺损，高血压是其最重要的独立危险因素，糖尿病也是其危险因素。

Objective To study the characteristics of the temporal and occipital lobe infarction visual field changes and its risk factors. Methods Retrospectively analyzed 95 cases treated in the Department of Ophthalmology in our hospital. The patients were diagnosed by CT screening for temporal and occipital lobe cerebral infarction with Octopus automated perimetry for inspection and statistical analysis. Results Visual field changes of homonymous hemianopia in 73 cases, accounting for 76.84%; the ipsilateral quadrantanopia in 13 cases accounting for 13.68%; tubular vision in 5 cases, accounting for 5.26%; central hemianopic scotoma in 3 cases, accounting for 3.16%; the lower half hemianopia in 1 case, accounting for 1.05%. Risk of hypertension in 66 cases, accounting for 69.47%; hypertension combined with diabetes mellitus in 4 cases, accounting for 4.21%; diabetes mellitus in 4 cases, accounting for 4.21%. Conclusions The temporo-occipital lobe infarction often results in homonymous hemianopic defects of visual field, hypertension is the most important independent risk factor, and diabetes mellitus is also a risk factor.
