Strabismic amblyopia is one of the most common types of amblyopia, and it cannot be cured if the patient is already an adult. The formation of amblyopia is due to abnormal development of the retinal function in childhood, which leads to the patient experiencing reduced vision.

Patients with strabismus have non-parallel visual lines of both eyes, which causes them to see inconsistent images, thus forming double images. This will make the brain suppress the vision of one eye to eliminate the symptoms of double images. The development of the retina in the suppressed eye will be abnormal, resulting in amblyopia.

Treatment needs to be carried out before the age of 12 by covering the eye with better vision, and then conducting amblyopia training to stimulate the development of the retinal function of the weaker eye, thereby gradually improving vision. Subsequently, strabismus corrective surgery is used to treat strabismus, restoring the eyes' visual lines to a parallel state. After adulthood, as the development of retinal function has stopped, amblyopia can no longer be treated.
