Summary
Pregnancy can cause vision changes, including a myopic shift, due to hormonal and weight fluctuations. Spectacle prescriptions should be postponed until after delivery to ensure accuracy.
Area of Science:
- Ophthalmology
- Obstetrics
- Endocrinology
Background:
- Pregnancy is associated with various physiological changes, including potential alterations in visual acuity.
- Hormonal shifts and weight gain during pregnancy are hypothesized to influence refractive error.
Purpose of the Study:
- To investigate and document changes in visual acuity during pregnancy and the postpartum period.
- To inform healthcare providers about the transient nature of pregnancy-induced refractive changes.
Main Methods:
- Observational study tracking visual acuity and refractive error in pregnant individuals.
- Analysis of changes from the first trimester through the postpartum period.
Main Results:
- A myopic shift in visual acuity was observed, typically starting in the second trimester.
- Refractive error stabilized postpartum, returning to the pre-pregnancy (first trimester) state.
- Hormonal changes and increased body weight were identified as contributing factors to the myopic shift.
Conclusions:
- Temporary changes in spectacle prescriptions during pregnancy are inadvisable due to expected stabilization postpartum.
- Gynecologists and optometrists should be aware of these visual changes and defer prescription updates until after delivery.
