Amblyopia is a common eye disease in childhood, and one of the causes of amblyopia is high refractive errors, including high hyperopia, high myopia, and high refractive errors. However, before diagnosing refractive error amblyopia, correct and effective refractive correction is the first step, and improper correction methods may affect the accuracy of our diagnosis and the effectiveness of treatment.
Repeated treatment of "amblyopia", but the vision has not been able to go up
On January 12, 2022, 7-year-old Le Le (pseudonym) and his mother came to the Department of Optometry and Myopia Prevention and Control of Guangzhou Aier Eye Hospital for treatment. Because Lele had previously been diagnosed with amblyopia in other hospitals, and the doctor said that the possibility of recovery was relatively slim, her mother was very anxious and worried. Director Zhang Xiaoxiao, who was interviewed by Lele's mother, said: "Lele wore glasses every day according to the doctor's requirements for 3 months, and insisted on visual training for the child, but the child's vision has not been able to go up. The child's myopia and astigmatism are so high, and there is amblyopia, will the child's vision be worse in the future..." Lele's mother expressed her concern to Director Zhang.
After a detailed examination, it was found that Lele's binocular myopia was 1000 degrees and 750 degrees, both eyes were astigmatism was 200 degrees, and after wearing glasses, the left and right eyes could only see 0.6. Director Zhang Xiaoxiao said that although the child has high myopia and astigmatism, it cannot be easily diagnosed as amblyopia, and it may also be that the original correction method is not the best choice, so please do not worry too much. High refractive error may trigger the occurrence of amblyopia, but clinically, myopia amblyopia is not common, because myopic babies usually see close-up is relatively clear, so the impact of vision development is not as serious as amblyopia caused by high hyperopia. If the child repeatedly does visual training due to inaccurate diagnosis, the result is not only that the child's vision cannot be improved, but also that the progression of myopia may be accelerated.
Use the right way to help your child regain sight
After the preliminary analysis, Director Zhang Xiaoxiao communicated with Lele's mother that she could try to choose to use a hard corneal contact lens, which is commonly known as an RGP mirror, to replace the ordinary frame mirror to correct the child's vision. Because RGP glasses can provide patients with better vision and visual quality than framed glasses. In this regard, Lele's mother, like many parents in the past, has issued such doubts: "Can such a small child use contact lenses?" Is it safe? ”
Rigid corneal contact lenses are divided into two kinds: OK mirrors and RGP mirrors, OK mirrors from the safety and necessity of consideration, generally require patients to be over eight years old; and RGP mirrors are mainly used for high refractive error, high refractive error and some special corneal refractive correction, in the case of necessity, not necessarily limited by age, of course, for younger children, need to have parental assistance, and need to be tested in formal medical institutions, and used under the supervision of doctors.
Actively cooperate with correction, and vision begins to recover
After listening to Director Zhang's analysis, Lele's mother decided to try the RGP mirror. After examination and try-on, Lele finally let go of a heart hanging in mid-air, because the corrected vision of the child's eyes reached 0.8! Although the early wearing requires some practice, it can make the child see the world more clearly, and take off the hat of "amblyopia", and the glasses vision during the review is basically maintained at 0.8 to 0.9. Director Zhang said that although Lele's corrected vision did not reach 1.0, it may be due to the fact that the problem was not found in time and the glasses were worn correctly, so it had a certain impact on the development of vision. However, this corrected vision has basically reached the standard, so there is no need for special visual training, so as not to aggravate the degree of myopia due to too much close-up training. Usually, Lele can stimulate the development of vision through some ball activities such as badminton and table tennis, and by training the ability of hand-eye coordination.
In this regard, Zhang Xiaoxiao once again reminded parents that although a high degree of refractive error may cause children to have amblyopia, it is necessary to be cautious whether this diagnosis is established! Because the impact of different refractive error components on visual development is actually different, especially in the absence of choosing a suitable correction program, blind diagnosis and blind visual training for children do not necessarily solve the child's vision problems.
