Measures of vernier acuity may correlate accurately with measures of Snellen acuity. We used the sweep visual evoked potential to determine whether vernier acuity is normal in children with delayed visual maturation (DVM).
Case series of two infants.
Thresholds for grating and vernier acuity were measured electrophysiologically in two infants with DVM using the sweep visual evoked potential. Acuity thresholds were calculated for each of these visual functions.
Two infants with DVM had normal thresholds for grating and vernier acuity, even though their visual behavior as determined clinically was abnormal.
Some children with DVM have normal acuity thresholds, even though the behaviors associated with vision are delayed or absent.
游标视力测量结果可能与斯内伦视力测量结果准确相关。我们使用扫描视觉诱发电位来确定视觉发育延迟（DVM）儿童的游标视力是否正常。
两名婴儿的病例系列。
使用扫描视觉诱发电位对两名患有DVM的婴儿进行电生理测量，以确定光栅视力和游标视力的阈值。计算每种视觉功能的视力阈值。
两名患有DVM的婴儿的光栅视力和游标视力阈值正常，尽管临床确定的视觉行为异常。
一些患有DVM的儿童的视力阈值正常，尽管与视力相关的行为延迟或缺失。
