For myopic children, first of all, through a series of examinations to rule out other causes that may cause vision loss. After that, an astigmatism examination will be performed. It can be categorized into slow dilation and fast dilation. For children younger than 12 years old, who have strong eye adjustment, it is necessary to use 1% atropine for slow dilation to completely remove the adjustment, while for teenagers older than 12 years old, who have reduced eye adjustment, the use of compound tropicamide for fast dilation will be able to remove the eye adjustment.
