AbstractAims/Background Pregnancy may cause physiological and pathological changes in multiple organs in a woman's body, including the heart, liver, and eyes. With rapid advances in societies and economies, the proportion of advanced maternal age (AMA) women has significantly increased. Here, we aimed to investigate the changes in arteriole retinal diameter, venule diameter, macular layer thickness, and arteriole to venule ratio (AVR) in this population. Methods This retrospective case-control study included 523 pregnant women (1046 eyes) and was performed on both eyes. In total, 318 subjects were included in the AMA group, and 205 subjects were included in the non-AMA group. Nonmydriatic fundus photography and optical coherence tomography (OCT) were performed on the same day, and the results were analyzed for the central retinal arteriolar equivalent (CRAE), central retinal venular equivalent (CRVE), AVR, and macular thickness (9 subfields) by integrative vessel analysis and automatic OCT software. Results In both eyes, the CRAE was significantly lower in the AMA group than that in the non-AMA group (p < 0.05; respectively). The CRVE in the AMA group was higher than that in the non-AMA group (p < 0.001; respectively). Compared to the non-AMA group, the AMA group exhibited a significant reduction in macular thickness within the inner nasal, outer nasal, and inner temporal subfields of both eyes (p < 0.05; respectively). Age was significantly correlated with CRVE and AVR in both eyes of pregnant women (CRVE: p < 0.0001; AVR: p < 0.01). Conclusion This study reports variations in the diameter of the retinal vasculature and the thickness of the macula in women of AMA. It is important to consider these changes when interpreting the adverse eye outcomes experienced by women of AMA.
