Summary

Central corneal thickness increased significantly in pregnant women compared to non-pregnant individuals. This change did not correlate with intraocular pressure or gestational week.

Area of Science:

  • Ophthalmology
  • Physiological Optics

Background:

  • Corneal thickness is a crucial parameter in ophthalmology.
  • Pregnancy-induced physiological changes may affect ocular structures.

Purpose of the Study:

  • To investigate changes in central corneal thickness during pregnancy.
  • To compare corneal thickness between pregnant, non-pregnant, and postpartum women.
  • To explore the relationship between corneal thickness, intraocular pressure, and gestational week.

Main Methods:

  • Central corneal thickness was measured in 89 pregnant women.
  • Comparison groups included 18 non-gravid and 17 postpartum women.
  • Intraocular pressure was also recorded.

Main Results:

  • Corneal thickness was significantly increased by 16 microns in pregnant women (P = .01).
  • No significant difference in corneal thickness was found between non-gravid and postpartum groups (P = .79).
  • No trend in corneal thickness was observed over the course of gestation.
  • Lowered intraocular pressure during pregnancy did not correlate with corneal thickness.

Conclusions:

  • Pregnancy is associated with a significant increase in central corneal thickness.
  • Corneal thickness changes during pregnancy are not influenced by gestational week or intraocular pressure.
  • Corneal thickness returns to baseline postpartum.
