[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 polar lesions in 53 cases with high myopia were investigated. Cases with low and moderate degrees of myopia were the controls. The results demonstrate that the visual field defects are present in the high myopic eyes and they are related to the degree of high myopia, the age of the patient and the severity of the posterior polar lesion. The visual field defects present multiform and multilevel in character and they do not completely correspond to the fundus lesions. The appearance of central relative scotomata in high myopic eyes detected by a quantified automated perimeter is prior to the appearance of macular lesions seen under an ophthalmoscope. Therefore, the quantified automated central visual field examination is helpful to the early diagnosis of macular disease in high myopia.
