| Popis: | Introduction: The structural and vascular changes in the retina and choroid in women in the third trimester of pregnancy were analyzed using optical coherence tomography angiography (OCTA). Methods: Forty women in the third trimester of uncomplicated pregnancy and 40 age-matched healthy women were included. Vascular density (VD) in the superficial and deep capillary plexuses (SCP/DCP), foveal density (FD), and foveal avascular zone (FAZ) area and perimetry measured with OCTA, as well as OCT measurements of central macular thickness (CMT) and choroidal thickness (CT) were compared between the groups. Correlations between structural OCT parameters and vascular OCTA metrics were analyzed. Results: The mean gestational age was 34 (28–41) weeks. Mean age was comparable in the groups ( p = 0.732). The pregnant women had significantly higher parafoveal DCP-VD ( p = 0.015), FAZ area ( p = 0.044), and FD ( p = 0.002). Mean subfoveal CT was 21 µm higher in pregnant women but was not significant ( p = 0.472). There was no difference in CMT ( p = 0.448). FAZ metrics were positively correlated with CT in pregnants and with CMT in the control group ( p 0.05). Conclusions: Considering the effects of the probable covariant factors CMT and CT, systemic changes in pregnant women in their third trimester may cause an increase in VD in the macula and parafoveal DCP. |
