Forty-four percent of eccentric fixations were changed to central fixation and 32% of the central scotomas were removed. 轻度弱视疗效好，注视性质越靠近中心凹疗效越好。
This will not only serve as a tracker, but it will also serve as a pacer for maintaining consistent speed and decreasing fixation duration. 这样笔就不仅是一个追踪器，而且还是定速器，能帮助维持恒定的速度，同时还能缩短注视时间。
