Patient's question:
Boy, 7 years old, the child's vision has deteriorated significantly. He was taken to the hospital for a thorough examination and was diagnosed with myopic amblyopia with strabismus. He is very worried about this situation and wants to ask how to treat the child's amblyopia.Doctor's answer:
Due to different visual acuity between the two eyes, the size and clarity of the retinal images are different. The fovea of the eye with higher refractive power appears larger and blurred, leading to insufficient fusion stimulation between the two eyes and inability to form binocular single vision, which results in passive suppression. For eyes with a refractive difference of 300 degrees or more, the eye with higher refractive power often develops amblyopia and strabismus, resulting in both passive and active suppression. The severity of amblyopia is not related to the degree of refractive error but is related to the nature of fixation. Eyes with central tend to have more severe amblyopia, and the nature of this type of amblyopia is similar to that of strabismic amblyopia, being functional and reversible. Clinically, it can sometimes be difficult to distinguish whether amblyopia is primary due to refractive error or secondary to strabismus. If this type of amblyopia is detected early and corrective glasses are worn promptly, it can be prevented.
