Abstract Purpose: To evaluate macular, peripapillary choroidal thickness and retinal nerve fiber layer (RNFL) thickness in different trimesters and compare the measurements with those of healthy non-pregnant women. Methods: A prospective comparative study included 45 healthy pregnant women in first trimester, 90 women in second, 45 women in third trimesters and 45 healthy no-pregnant women as the control group. Macular choroidal thickness was measured at the subfoveal, 1mm temporal and 1mm nasal to the fovea using enhanced depth imaging optical coherence tomography (EDI-OCT). Peripapillary choroidal thickness and RNFL thickness parameters were automatically calculated by the Spectralis OCT. These parameters were analyzed among groups. Results: The subfoveal, temporal and nasal choroidal thickness were all significantly thicker in second trimesters, comparing with those parameters in first, third trimesters and the control group (all P<0.05). The peripapillary choroidal thickness was significantly increased at temporal, nasal, nasal inferior, temporal inferior and global positions during pregnancy among the 4 groups (all P<0.05). The RNFL thickness was also significantly increased in pregnant women at nasal superior and nasal inferior quadrants.Conclusions: Our results suggested that macular choroidal thickening appeared in second trimester. And peripapillary choroidal thickness and RNFL thickness also became thickening in pregnant women comparing with no-pregnant women as a whole.

The Relationship

The body changes markedly during pregnancy; each system behaves differently from a nonpregnant state. As the eyes are the only windows to see directly what is going on in the internal environment, more and more researches have been done to explain the association between ocular changes and the physiological and pathological changes during pregnancy. The choroid is one of the critical parts of the eye, providing nutrition. And abnormal choroid may result in ocular dysfunction and visual problems. As the optical coherence tomography develops, a rapid, direct, noninvasive, and nontoxic way is available to obtain the choroid situation of pregnant women, which may explain the mechanism of pregnancy-related eye diseases. This review would summarize relevant original articles published from January 1, 2008 to December 1, 2016 to assess the changes of choroidal thickness (CT) with enhanced depth imaging optical coherence tomography (EDI-OCT) during pregnancy. And the relationship between choroidal thickness changes and pregnancy remains uncertain. To our knowledge, this is the first review of EDI-OCT in assessing the choroidal thickness of the pregnant women.

Background/Aim: Pseudoexfoliation (PSX) syndrome is associated with blood flow disturbances; however, its exact effect on choroidal blood flow and thickness remains to be elucidated. This study compared subfoveal choroidal thickness in normal eyes and in eyes with PSX using enhanced depth imaging optical coherence tomography (EDI-OCT). Methods: This prospective, cross-sectional study included 35 eyes of 35 patients (20 males, 15 females) with unilateral or bilateral PSX and 26 eyes of 26 healthy volunteers (13 males, 13 females). Besides a comprehensive ocular and physical examination, all subjects underwent EDI-OCT examination using an Optovue RTVue OCT device (Optovue Inc., Fremont, Calif., USA). Results: The mean choroidal thickness (CT) and ocular perfusion pressure (OPP) were lower in the PSX group than in the healthy controls (249.4 ± 46.3 vs. 282.5 ± 55.8 µm, p = 0.014 and 40.7 ± 5.8 vs. 44.3 ± 4.3 mm Hg, p = 0.007, respectively). In addition, both systolic blood pressure and diastolic blood pressure measurements were lower among the PSX patients. However, no correlation was found between CT and OPP. Conclusion: The findings of this study suggest that PSX is associated with an overall thinning of the subfoveal choroid and a significant decrease in OPP. Future studies are warranted to further examine these relations.
