It is seen when an individual tracks (pursuit movement) a moving object with their eyes, which then moves out of the field of vision, a point at which their eyes move back to the initial position (saccade movement) when they first saw the object.

WebbBy definition, nystagmus starts by a slow movement of the eye away from the visual target. The second movement brings the eye back to the visual target. If the second movement is slow, the nystagmus is said to be pendular. If this second movement is quick, the nystagmus is called jerk nystagmus. WebbOne of the common causes for lazy eye is strabismus. When the child's eyes are pointed in different directions, the child has to use one eye at a time to avoid seeing double. If he or she uses one eye more than the other, the other eye becomes lazy. Children without strabismus can also develop a lazy eye.
