BACKGROUND/AIMS: Periventricular leucomalacia (PVL) is a lesion in the immature brain involving the optic radiation. Children with PVL have visual problems including crowding, visual field defects, strabismus, and visual perceptual/cognitive deficits, together with nystagmus. They often have optic nerve hypoplasia seen either as small discs or as large cupping of normal sized optic discs. This study aimed to perform eye movement recordings in a group of children with PVL in order to characterise and classify the nystagmus.
19 children with PVL on cerebral imaging underwent eye movement recordings with the Ober-2 infrared reflection technique.
16 of the 19 subjects had horizontal nystagmus.
The present study shows that nystagmus is commonly seen in children with PVL.
背景/目的：脑室周围白质软化（PVL）是未成熟脑涉及视辐射的一种病变。患有PVL的儿童存在视觉问题，包括视觉拥挤、视野缺损、斜视、视觉感知/认知缺陷以及眼球震颤。他们常伴有视神经发育不全，表现为视盘小或正常大小视盘的大杯状凹陷。本研究旨在对一组PVL患儿进行眼动记录，以对眼球震颤进行特征描述和分类。
19例经脑部影像学检查确诊为PVL的患儿采用Ober-2红外反射技术进行眼动记录。
19名受试者中有16名出现水平性眼球震颤。
本研究表明眼球震颤在PVL患儿中很常见。
