[Ocular changes during pregnancy]

Pregnancy is often associated with ocular changes. Most of them are specifically associated with the pregnancy itself, rare disturb the normal visual function and are transient in nature. The ocular effects of pregnancy may be divided into physiologic changes, pathologic conditions or modifications of pre-existing conditions. Pregnancy is associated with changes in corneal sensitivity and thickness, decreased tolerance to contact lenses, decreased intraocular pressure, can affect refractive error. Pathologic conditions reported to develop during pregnancy include hypertensive and vascular disorders, central serous chorioretinopathy, uveal melanoma and others. The most significant modified pre-existing condition is diabetes mellitus. Pregnant women are at increased risk for the progression of preexisting proliferative diabetic retinopathy, and diabetic women should see an ophthalmologist before pregnancy or early in the first trimester. This review describes various ocular changes that occur during pregnancy and summarizes the ocular disturbances in these three categories.
