Embarazo y salud ocular: ¿Por qué crecen las dioptrías?

During pregnancy a woman’s body experiences many changes, such as the appearance of stretch marks, weight gain or constipation. These are the most common and well-known changes, but there are many others that are also common and need to be taken into account.

Pregnancy can bring about a loss of visual acuity. The reason is that during pregnancy hormones cause more fluid retention than usual, resulting in an increase in the thickness and curvature of the cornea and lens, which results in an increase in myopia in pregnant women.

This increased myopia usually occurs in the first term of pregnancy and disappears between 6 and 8 weeks after giving birth, but in some cases it never completely goes away, although this is unusual. The reason for our eyesight returning to its normal level is that after childbirth hormone levels drop and everything returns to normal.

There is no way to know whether the myopia acquired during pregnancy will disappear or not, although it is more likely to completely disappear in women who have no visual defects before pregnancy than in those who already suffer from myopia.

Diabetes in pregnancy

Women with diabetes should be monitored by a doctor during pregnancy, mainly because of the risk of diabetic retinopathy. In fact, it is estimated that 3 in 10 women will develop this eye condition. One of the symptoms of diabetic retinopathy is the appearance of damage to the retinas of diabetic patients. This can range from minimal damage that does not require treatment up to injuries that require surgical treatment.


Apart from the diseases mentioned above, pregnancy is a condition in which other related eye disorders such as dry eye may appear due to decreased tear secretion.

If you suffer from one of these diseases, it should be taken into account when performing activities such as driving, by avoiding driving at night and glare.

The best way to avoid problems during pregnancy is to go to an ophthalmologist for a visual examination and to continue monitoring throughout pregnancy. At Vissum we have specialised medical teams that will undertake customised eye monitoring of each woman during pregnancy.
