Study on macular retinal thickness in healthy pregnant women / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM: To evaluate the physiologic change of retinal thickness during pregnancy. METHODS:Forty cases ( 80 eyes ) were included two groups40 eyes ( 20 cases ) in healthy pregnant women group (including in the second and last trimester), and 40 eyes (20 cases) in healthy nonpregnant women group ( control group ) . The macular volume, average thickness, central subfield thickness and retinal thickness of other parafoveal areas were measured by optical coherence tomography scan. RESULTS: The macular volume was 10. 06±0. 41mm3 and 9. 87±0. 30mm3 in healthy pregnant women group and control group respectively. The average thickness was 279. 43±10. 86μm and 274. 25±8. 07μm in healthy pregnant women group and control group respectively. The central subfield thickness was 235. 15±15. 05μm and 233. 00±15. 81μm in healthy pregnant women group and control group espectively. Statistically significant difference was found in macular volume and average thickness (P CONCLUSION:The macular retinal thickness increases during pregnancy in the second and last trimester. The physiologic change of retinal thickness should be considered when evaluating pathologic retinal disease of pregnant women.
