PURPOSE
To report alterations of electrophysiologic tests, including the multifocal electroretinogram, in a case of acute zonal occult outer retinopathy.
METHOD
We recorded photopic, scotopic, and single-flash electroretinograms and a multifocal electroretinogram in a 47-year-old woman with acute zonal occult outer retinopathy in the right eye.
RESULTS
Her visual acuity was 20/20 in the right eye throughout the follow-up period. The electroretinograms indicated retinal impairment of the right eye, predominantly in the cones. The multifocal electroretinogram showed reduced responses corresponding to the visual field defect of the static perimetry.
CONCLUSIONS
In acute zonal occult outer retinopathy, impairment of the retinal area results in a visual field defect. The multifocal electroretinogram can be useful in determining the location of the defect.
目的
报告急性区域性隐匿性外层视网膜病变患者的电生理检查结果，包括多焦视网膜电图的改变。
方法
我们对一名47岁右眼患有急性区域性隐匿性外层视网膜病变的女性患者进行了明视、暗视和单闪光视网膜电图以及多焦视网膜电图检查。
结果
在整个随访期间，她右眼的视力为20/20。视网膜电图显示右眼视网膜功能受损，主要累及视锥细胞。多焦视网膜电图显示与静态视野检查视野缺损相对应的反应降低。
结论
在急性区域性隐匿性外层视网膜病变中，视网膜区域的损害导致视野缺损。多焦视网膜电图有助于确定缺损的位置。
