Refractive Amblyopia

Refractive amblyopia is more common in congenital hyperopia or hyperopia or astigmatism in the early postnatal period. Due to the high degree, it cannot be corrected during development, so that the resulting image cannot be clearly focused on the macular fovea, resulting in the inhibition of visual development. Amblyopia caused by compound hyperopia astigmatism and mixed astigmatism is common in clinic. The influence of astigmatism on visual development is higher than that of hyperopia of the same degree, and the treatment process is also relatively long.

1. Clinical symptoms:

Young children may not have any symptoms, older children may complain of blurred vision, and children like to put the vision in front of them when they see near objects. Vision is low and cannot be corrected, with obvious ametropia, which may have characteristics similar to other types of amblyopia.

2. Inspection and diagnosis:

There are abnormalities found in the visual examination of children. Optometry is very important for children with amblyopia, which can judge the nature and degree of ametropia. For children with amblyopia, subjective and objective optometry under ciliary muscle paralysis is generally required. Since children's vision is in the process of continuous development and their refractive state is constantly changing, they are generally followed up regularly for 3 to 6 months, and re optometry is required for 6 to 12 months. If there are major changes, re issue the prescription for glasses. Other examinations including strabismus examination, fixation property examination and VEP examination are helpful for diagnosis.
