An eye exam during pregnancy is not mandatory. Your obstetrician decides if you need an eye exam, and will invariably refer you to an eye doctor if you have high blood pressure or diabetes. In these expectant moms, any change in vision may signal an emergency
This is because both high blood pressure and blood sugar can affect the eyes, especially during pregnancy.
Preeclampsia, a potentially serious problem that occurs in 5% to 10% of pregnancies is characterised by high BP and the presence of protein in urine. It can result in vision changes ranging to a temporary blur to loss of vision, sensitivity to light, auras, and flashing lights.
Any of these symptoms means you should call your doctor immediately and go to the hospital emergency.
Diabetes, on the other hand, can lead to changes in the retina which do not threaten your general wellbeing, or the baby’s; but can potentially affect vision.
Also, the fluid retention during pregnancy can change the thickness and shape of your cornea, and result in blurry or distorted vision. Usually, these changes are temporary, and your vision becomes normal after pregnancy or after you stop breast feeding.
If your vision alters significantly, however, talk to your doctor. You may need to change your prescription if you wear glasses. Usually the shape of your cornea will revert to normal after your pregnancy is over.
You will also notice that your eyes maybe drier than normal, and there may be an associated discomfort. Dry eyes can make wearing contacts irritating and uncomfortable.
You may use artificial tears which are available over the counter, to lubricate your eyes. Some artificial tears may have preservatives so, check with your doctor first to make sure the ingredients are safe for you during pregnancy.
