Abstract
PurposeTo evaluate the effects of obesity on ocular blood flow including choroidal thickness and retrobulbar blood flow values in comparison with healthy subjectsMethodsThe 102 eyes of 102 female patients were included in this prospective study.Color Doppler ultrasonography (CDU) was used to evaluate the retrobulber vessels.Choroidal thickness was measured by using the optical coherence tomography (OCT). ResultsThere was a significant difference in IOP values within the groups with the highest values in group 3 and the lowest in group 1.There was also a positive correlation between BMI and IOP. The CT was found to be statistically significantly lower in group 2 and group 3 than in the control group at all measurement points. The choroidal thickness was also statistically significantly lower in group 3 than in group 2 at the subfoveal, nasal 500 µm, and the temporal 500 and 1000 µm measurement points.The mean CRA PSV and EDV values were lower in group 2 and group 3 than in group 1, while group 3 had the lowest mean CRA PSV value among the groups. When compared to group 1, the OA EDV value was lower only in group 3 while the OA PSV value was statistically significantly lower in group 3 than in both group 2 and group 1. There was no significant difference between the groups in terms of RI and PI.ConclusionsObesity can create a predisposition to ocular pathologies both by increasing the IOP and decreasing the retrobulbar and choroidal blood flow.
