Abstract: high myopia refers to ametropia with myopia degree higher than 600 degrees, which may cause fundus degeneration due to excessive elongation of ocular axis. High myopia is one of the high incidence groups of retinal detachment, especially in the case of excessive force, it will increase the possibility of retinal detachment.
pregnant in October, once childbirth is not an easy process for every mother, especially when it comes to the final birth. For some nearsighted expectant mothers, there is a frightening saying: highly nearsighted pregnant women will have retinal detachment during spontaneous labor, resulting in blindness. Is there a basis for this statement?
why do some people think that high myopia cannot produce naturally
high myopia refers to ametropia with myopia degree higher than 600 degrees, because the ocular axis is excessively elongated, which may cause degenerative lesions of the fundus. High myopia is one of the high incidence groups of retinal detachment, especially in the case of excessive force, it will increase the possibility of retinal detachment.
pregnant women need to hold their breath and exert themselves during spontaneous labor. Therefore, in theory, pregnant women with high myopia may have retinal detachment.
if you check the literature related to high myopia and cesarean section, you will find that most of the literature comes from Eastern Europe. Some ophthalmologists will suggest that cesarean section should be the main mode of delivery for patients with high myopia, because the patient needs to hold his breath for a long time during vaginal delivery, which will increase the risk of retinal detachment—— Duan Tao, President of Shanghai No. 1 maternal and child health care hospital,
do a good job in the inspection, and those who want to follow can follow
. Although the statement that high myopia is not suitable for spontaneous delivery is not groundless, you expectant mothers still need not be too nervous. In fact, many studies show that, There is no significant increase in ocular complications (such as retinal detachment, which is most feared) caused by spontaneous delivery in pregnant women with high myopia compared with non high myopia.
Even high myopia does not mean that pregnant women must have fundus lesions. Pregnant women with high myopia may have the risk of retinal detachment during delivery, but it also depends on other factors during delivery. If the pelvic floor is normal, the woman is healthy and strong, the fetus is healthy, the fetal position is correct, and the fetus is in a basin, then it is entirely possible to choose spontaneous labor.
out of a cautious attitude, expectant mothers with high myopia can have prenatal eye examination, especially fundus examination, to assess the existence of risk factors. If high-risk factors of retinal detachment, such as retinal holes, are indeed found, preventive laser treatment can be carried out.
in short, the probability of retinal detachment in spontaneous labor of high myopia is far less than that rumored on the Internet. As long as they are examined, mothers to be with high myopia can give birth safely and smoothly.
expectant mothers should know more about these things than retinal detachment.
● they are more likely to dry their eyes during pregnancy.
about 90% of the tear is water, which can wet the whole upper tissue and cornea of the eyes. During pregnancy, the hormone level of pregnant women changes, so that the water in tears is easier to evaporate than before pregnancy, and the tears will thicken, which will weaken the function of wetting the cornea and conjunctiva of the eyes, which is easy to cause the symptoms of “dry eyes”.
● decreased corneal sensitivity
in the early stage of pregnancy, due to the change of hormone level, corneal sensitivity will be reduced, affecting corneal reflex and eye protection function. Tears are not enough to protect the eyes, so the eyes are prone to redness, fatigue and foreign body sensation.
● corneal radian changes
studies show that corneal radian will become steeper during pregnancy, especially at the end of pregnancy. After the corneal radian becomes steep, the diopter will change to a certain extent. Therefore, the glasses usually worn may not be able to correct the vision well, but most cases can be recovered around 6 weeks postpartum.
