Abstract: parents should never relax their vigilance because of a doctor’s pseudomyopia. For children in growth and development, they should not only measure whether their eyes are normal by naked eye vision, but also monitor at least three indicators: naked eye vision, diopter and axial length.
for most parents of children with myopia, when they go to the hospital for an optometry, they hear that it is pseudomyopia. They immediately breathe a sigh of relief. Thank God it is not true myopia. Unexpectedly, within six months, these pseudomyopia has become true myopia, and the child’s eyesight has begun to deteriorate rapidly. What’s the matter?
first let’s look at what is pseudomyopia. In short, the difference in diopter between before and after mydriasis is called pseudomyopia when the hospital does mydriatic optometry. There are generally three situations, such as:
1 Before mydriasis -2.0 (myopia 200 degrees), after mydriasis -1.5 (myopia 150 degrees)
2, before mydriasis -0.75 (myopia 75 degrees), after mydriasis is 0, without myopia
3, before mydriasis -0.50 (myopia 50 degrees), after mydriasis + 0.50, (hyperopia 50 degrees)
In the first case, parents will pay attention immediately, while in the second and third cases, parents feel light. This relaxed child will soon become true myopia. Why?
in fact, most of today’s children have true myopia at the age of three or four. True myopia mainly refers to myopia caused by the lengthening of the eye axis. Under normal circumstances, children have hyperopia reserve. For example, a 6-year-old child should have 200 degrees of hyperopia under normal circumstances. We also call it physiological hyperopia reserve, but most of today’s children have no hyperopia reserve. That is to say, compared with normal circumstances, these children have more than 200 degrees of nearsightedness, the ocular axis has become longer, and true myopia has occurred.
once true myopia occurs, sorry, before adulthood, there is no other way except wearing glasses, because it is, no! But! Inverse! of (highlight)
myopia: Rome wasn’t built in a day
a more cruel fact is that there are fewer and fewer children with pseudomyopia, and they are found to be true myopia.
do children have “myopia prone body quality”?
both parents are myopic
are Asians with higher myopia rate than Westerners.
have less hyperopia reserves since childhood. After understanding this principle, parents must not relax their vigilance because of a doctor’s false myopia. For children in growth and development, We should not only measure the normal development of eyes by naked eye vision, but also monitor at least three indicators: naked eye vision, diopter and eye axis length.
and now children around the age of 5 generally have no hyperopia reserve, and the ocular axis is significantly higher than the normal value, that is to say, they are true myopia. Unfortunately, many parents feel good when they see their children’s vision of 0.8 and 1.0, but in fact it has been very serious. 99% of parents have missed the best expectation of their children’s vision.
