What is Amblyopia?
People do not have perfect vision from birth. As the brain is stimulated by seeing various things in daily life, the eye function will gradually develop. Amblyopia is caused by a lack of information for some reason, which prevents the development of the eye.
Major Causes of Amblyopia
From about one month to eight years of age, amblyopia can occur when refractive errors such as strabismus or farsightedness are left untreated or when vision is obstructed by an eye patch. They are classified into four types.
Strabismic Amblyopia
Strabismus causes double vision. In order to prevent the resulting visual confusion, the brain may suppress the use of one eye. The suppressed eye has no chance to develop vision, resulting in amblyopia.
Ametropic Amblyopia
It is caused by farsightedness or astigmatism, which makes it difficult to see objects, thereby preventing the eyes from providing stimulation to the brain.
Anisometropic Amblyopia
It occurs when one eye has normal vision with no refractive error, but the other eye has farsightedness that causes it to be unused.
Deprivation Amblyopia
It occurs when children are unable to see due to the use of an eye patch, congenital cataracts, or congenital ptosis during the developmental period of vision.
Treatment for Amblyopia
The best treatment is to show the correct view to the amblyopic eye. Therefore, the basic principle is to make children wear the correct glasses, show them things properly, and continue to stimulate their brains through their eyes.
