How to correct mild strabismus more effectively

The occurrence of strabismus cannot be ignored. After all, if this problem develops and becomes more serious, it may cause more adverse effects. Therefore, different treatment methods should be adopted according to the degree of strabismus, and surgical correction should be performed if necessary.

1. Use different treatment methods according to the degree of strabismus: For asymptomatic latent strabismus, no treatment is required because children have strong fusion and convergence abilities. However, some children with latent strabismus experience symptoms of visual fatigue such as eye swelling, orbital pain, and headache after viewing objects at close range, and appropriate treatment can be used. For esotropia, the pupil needs to be dilated and the eyes need to be refraction tested. Those with hyperopia should be fitted with appropriate glasses. For exotropia, convergence training can be performed to strengthen the adductor muscles of both eyes to overcome the exotropia. If the effect is not good, prism glasses can be worn. For exotropia greater than 10° (20Δ) when looking at near objects, surgical treatment can be considered.

2. Intermittent esotropia is mostly hyperopia. Once discovered, the pupil should be dilated for refraction and corrected with adequate hyperopia glasses. After wearing the glasses, the intermittent esotropia can usually be completely corrected. Children with intermittent exotropia should undergo strabismus and synoptophore examinations to understand their binocular vision function, and receive surgical treatment as soon as possible before binocular single vision function is lost. If binocular single vision is lost, surgical correction before the age of 7 may still allow recovery to normal. If the degree of strabismus is very small, you can wear negative glasses and do convergence training, but it can only alleviate the symptoms and is not easy to cure.

3. Use different treatment methods according to the different causes of strabismus: Although congenital esotropia in common strabismus has nothing to do with eye adjustment, it has a great impact on the development of binocular single vision function. The best treatment is surgical correction at the early stage of visual function development at the age of 2. Esotropia that occurs after the age of 2 to 3 is mostly related to excessive accommodative convergence caused by hyperopia. This type of strabismus requires full mydriasis and eye examination. Those with hyperopia should be fitted with adequate glasses and wear them for 3 to 6 months to correct or partially correct the strabismus, and then surgical treatment can be performed for any remaining esotropia. If the esotropia does not change after wearing glasses, the only treatment is surgery. If the strabismus is completely corrected, you can continue to wear glasses. If the hyperopia is very high, you can also correct the strabismus through surgery and reduce the degree of glasses you need to wear.

For patients with manifest exotropia, after excluding obvious refractive errors, the principle of treatment is also early surgery. If the eyesight is poor, the pupil needs to be fully dilated and the eyes need to be tested. If the exotropia is caused by something that does not require adjustment, the exotropia may be corrected by wearing appropriate myopia glasses regularly. If it is hyperopia combined with amblyopia, glasses should be fitted according to the principle of using the lowest lens power to achieve the best corrected vision, and amblyopia training should be performed. If exotropia still exists, surgical treatment is required.
