The orbicularis oculi muscle contracts in response to photic stimulation. It was recorded as the microvibration of the eyelid contraction and it is called the photo-evoked eyelid microvibration (MV). MV was recorded using a special transducer on the central part of the upper eyelid from 167 subjects free of any neurological abnormalities. One G of the vibration was converted into 100 mV. The normal value was shown in newborns and children. The latency was 171.0 +/- 30.5 msec in newborns, 70.3 +/- 12.3 msec in 4 to 5 year-olds, 46.3 +/- 11.2 msec in 7 to 8 year-olds and 57.0 +/- 4.9 msec in adults. The latency of MV became shortened with growth. It is thought that the shortening of the latency during maturation is related to the myelination of the brainstem reticular formation and the maturation of the retina.
眼轮匝肌会对光刺激产生收缩反应。它被记录为眼睑收缩的微振动，被称为光诱发眼睑微振动（MV）。使用特殊传感器在上眼睑中央部分对167名无任何神经异常的受试者记录MV。1G的振动转换为100mV。新生儿和儿童显示出正常值。新生儿的潜伏期为171.0±30.5毫秒，4至5岁儿童为70.3±12.3毫秒，7至8岁儿童为46.3±11.2毫秒，成人为57.0±4.9毫秒。MV的潜伏期随着生长而缩短。据认为，成熟过程中潜伏期的缩短与脑干网状结构的髓鞘形成和视网膜的成熟有关。
