高度近视眼的静态中心视野改变和眼底后极部病变的关系

利用Ｏｃｔｏｐｕｓ视野分析仪检查５３例高度近视眼的静态中心视野并观察其后极部的眼底改变，同时以低中度近视眼作为对照。结果表明：高度近视眼的中心视野损害与患者的屈光度、年龄以及后极部眼底改变有关，其改变呈现形态、程度各异的特点，与眼底后极部改变的形态不完全对应。高度近视眼中心视野相对暗点的出现早于眼底镜下黄斑形态的改变，对于早期诊断有一定帮助。

The correlation between changes of static central visual fields and posterior polar lesions in high myopia

The static central visual fields tested by an Octopus Field Analyzer and posterior polarlesions in 53 cases with high myopia were investigated. Cases with low and moderate degrees of myopiawere the controls.The results demonstrate that the visual field defects are present in the high myopiceyes and they are related to the degree of high myopia, the age of the patient and the severity of the pos-terior polar lesion. The visual field defects present multiform and multilevel in character and they do notcompletely correspond to the fundus lesions. The appearance of central relative scotomata in high myopiceyes detected by a quantified automated perimeter is prior to the appearance of macular lesions seen un-der an ophthalmoscope,Therefore,the quantified automated central visual field examination is helpfulto the early diagnosis of macular disease in high myopia.
