Abstract: when children have anisometropia in both eyes, the eyes with small refractive power will see things clearly. When both eyes see an object at the same time, the brain cannot integrate two objects with different clarity into one., Many myopic patients are very confused about this matter: one eye is myopic, one eye is not myopic, is it necessary to correct it? Let’s say, you can see clearly without glasses, but sometimes your eyes are easy to be tired, and even a little dizzy and disgusting… What should I do?, Generally speaking, in the process of eye development, there are some differences in the refractive status of almost all people, and it is very rare to have complete consistency. However, if the diopter difference of both eyes is more than 250 degrees, it can usually be called anisometropia in clinic. If not corrected in time, it can lead to faster decline of “poor eye” vision, monocular amblyopia, exotropia, etc., If there is anisometropia in both eyes, it will have a great impact on the development of their eyes, which is mainly reflected in the following aspects: the vision of “poor eyes” decreases faster, and there is a principle in the use of eyes – “use in and waste out”, that is to say, good eyes are often used, and bad eyes are gradually abandoned, In this way, the eyes with poor eyesight will have the phenomenon of rapid increase in myopia and rapid decline in eyesight., It can lead to monocular amblyopia. When the child’s two eyes have anisometropia, the eyes with small diopter will see things clearly. When both eyes see an object at the same time, the brain cannot integrate two objects with different clarity into one. When this happens, the brain will command the eye with low refractive power to work and inhibit the eye with high refractive power to work. Over time, the eye with large refractive power will develop into amblyopia., Cause monocular exotropia,
many myopic patients are confused about this matter: one eye is myopic, one eye is not myopic, is it necessary to correct it? Let’s say, you can see clearly without glasses, but sometimes your eyes are easy to be tired, and even a little dizzy and disgusting… What should I do?
generally speaking, in the process of eye development, there are some differences in the refractive state of almost all people, and the completely consistent ones are rare. However, if the diopter difference of both eyes is more than 250 degrees, it can usually be called anisometropia in clinic. If not corrected in time, it can lead to faster decline of “poor eye” vision, monocular amblyopia, exotropia, etc.
if anisometropia exists in both eyes, it will have a great impact on the development of their eyes, which is mainly reflected in the following aspects:
“poor eyes” have faster visual acuity decline.
eyes have a principle in use – “use in advance and discard out”, that is to say, good eyes are often used, and bad eyes are gradually abandoned, In this way, the eyes with poor eyesight will have the phenomenon of rapid increase in the degree of myopia and rapid decline in eyesight.
can lead to monocular amblyopia
when a child’s two eyes have anisometropia, the eyes with small refractive power will see things clearly. When both eyes see an object at the same time, the brain cannot integrate two objects with different clarity into one. When this happens, the brain will command the eye with low refractive power to work and inhibit the eye with high refractive power to work. Over time, the eye with large refractive power will develop into amblyopia.
lead to monocular exotropia
when the child’s two eyes have anisometropia, the visual development of the eye with poor vision will also be inhibited. If there is no effective treatment, the eye with poor vision may develop into exotropia over time.
and
eyes are easy to fatigue. Anisometropia of
and
causes great difference in binocular power, which is easy to lead to visual fatigue, dry eyes, tears, headache, nausea, dizziness and other consequences. In addition, there may be deviation in judging distance and angle. When walking or driving, it is easy to endanger their own safety. How to correct the Anisometropia of
and
?
for anisometropia, the most common correction methods are wearing frame glasses, contact lenses or excimer laser surgery.
for teenagers, wearing frame glasses is very effective. Therefore, we generally carry out full correction or close to full correction for children with anisometropia (i.e. corrected visual acuity reaches 1.0), supplemented by binocular visual function training and masking treatment. Especially children under the age of 12 should correct all refractive errors as soon as possible, consolidate their binocular vision and prevent the emergence and development of strabismus and amblyopia.
for adults, contact lenses or refractive surgery can be used to treat anisometropia. At present, the excimer laser surgery most commonly used in the treatment of anisometropia includes PRK, LASIK, ICL and so on. How does
and
prevent anisometropia?
in daily life, do not look sideways when looking at close objects. The objects you see should be placed in front of your eyes and watched at the same time. Habitual sleeping on your side and incorrect pen holding posture may lead to varying degrees of anisometropia, which needs to be corrected in time. In addition, vitamin A and collagen can be supplemented appropriately to help alleviate visual fatigue and protect your eyes.
