Symptoms of amblyopia in children

summary

Amblyopia is defined as amblyopia if there is no organic eye disease and the corrected visual acuity is less than 0.9. Amblyopia is a common pediatric eye disease in ophthalmology clinic. It is a symptom of amblyopia in infants and young children who can not receive appropriate visual stimulation due to various reasons such as perception, movement, conduction and visual center? Next, I'd like to share my views with you.

Symptoms of amblyopia in children

The uncorrected visual acuity and corrected visual acuity of amblyopia were lower than 0.9. There was a history of occlusion, strabismus and / or extraocular muscle surgery in childhood. The corrected visual acuity was lower than that of normal children of the same age, mostly monocular or binocular. It's easier to recognize the same size of sight mark than the person who arranges them.

Amblyopia may occur in children with concomitant strabismus because both eyes cannot focus on the same object simultaneously. Because children's brain is relatively easy to adjust and adapt, it will inhibit the blurred image obtained by one eye, interfere with the visual development of the brain, resulting in the decline of the visual acuity of the eye, that is amblyopia. When the degree of binocular deviation is very small, it is difficult to detect. However, if the degree of strabismus is very small, severe amblyopia may occur, which should not be ignored clinically.

Binocular anisometropia can lead to amblyopia. The eyes with low degree of ametropia provide relatively clear retinal image. The brain chooses the image of the eye and suppresses the blurred image of the other eye with high degree of ametropia, resulting in amblyopia. Children with asymmetric hyperopia need special vigilance,

matters needing attention

Fine eyesight training: after children wear corrective glasses, they are accompanied by their parents for needle and bead training. Wear 200 ~ 300 needles or 200 ~ 300 beads each time to promote hand eye coordination and improve vision.
