一、伴随视觉的眼球运动种类当头部不动观看运动着的目标时,出现平滑追踪跟运动(smooth persuit,SP)、冲击性眼运动(saccade)或视运动性眼震(opt-okinetic nystagmus,OKN)。当头部运动观看目标时,出现代偿性前庭性眼运动或旋转眼震的前庭性眼运动。这些眼球运动是使网膜像安定,获得良好的视力所必需的生理性眼运动。SP 于不十分大的视角范围内观看平滑运动的小目标时出现,也可以叫做视标追踪眼运动或 First, the type of eye movement accompanied by vision When the head does not move to watch the movement of the target, the smooth follow-up with the movement (smooth persuit, SP), impact of ophthalmocomotion (saccade) or optokinetic nystagmus , OKN). When the head moves to view the target, there is compensatory vestibular ocular movement or spinocerebellar ocular movement. These eye movements are physiological ocular motions that make the omentum as stable and provide good vision. SP does not appear in a very large range of viewing smooth movement of small targets appear, can also be called the visual target tracking eye movement or
