Three major symptoms of congenital amblyopia

Congenital amblyopia is a genetic disease that refers to the presence of amblyopia symptoms from birth. Abnormal vision will greatly affect a person's normal life. If amblyopia is severe, you need to go to the hospital for treatment in time. In addition, congenital amblyopia has some complications, such as congenital ptosis, corneal leukoplakia, congenital cataracts, etc. The following is a detailed introduction to these three symptoms.

1. Congenital ptosis

If congenital ptosis is not treated in time, it will cause children to suffer from amblyopia, so parents need to be vigilant. Generally, the lower edge of a normal person's upper eyelid is below the upper edge of the cornea, and the upper eyelid only covers about 1/6 of the cornea, so the upper eyelid will not affect the entry of light into the pupil. However, if the levator palpebrae superioris muscle is slightly underdeveloped, it will cause ptosis, resulting in partial obstruction of the pupil. If the levator palpebrae superioris muscle is severely underdeveloped, complete ptosis may occur and visual development will be severely impaired, resulting in severe amblyopia.

2. Corneal Leukoplakia

Corneal leukoplakia is one of the causes of amblyopia, so if parents want their children to stay away from amblyopia, they need to take their children to a regular ophthalmology hospital for treatment in time. Ophthalmologists point out that the cornea is located at the front end of the eye's refractive system and is often exposed to the air and comes into contact with bacteria, viruses and other pathogenic microorganisms, making it more prone to infection and trauma.

3. Congenital cataract

Congenital cataracts can also cause amblyopia in children. Therefore, parents should take their children to a regular ophthalmology hospital in time to treat congenital cataracts, so that the children can stay away from cataracts and amblyopia.

People with severe amblyopia often use the retina next to the macula instead of the macula for fixation because the macula has poor fixation ability. Eccentric fixation refers to fixation outside the fovea. There are many theories about its formation, but its manifestations include parafoveal fixation, peripheral fixation, paramacular fixation, and migratory fixation. Eliminate inhibition, improve vision, correct eye position, and train macular fixation and fusion functions to restore binocular vision function. The therapeutic effect of amblyopia is related to age and the nature of fixation. It is better at 5 to 6 years old and worse after 8 years old. Central fixation is better and paracentral fixation is worse.
