摘要
PurposeTo evaluate the effect of weight loss on the retrobulbar hemodynamics in patients who had undergone bariatric surgery for obesity using color Doppler ultrasound (CDU) and to evaluate correlations with intraocular pressure (IOP) changes measured using Goldman applanation tonometry.MethodsThirty-two patients were included in this prospective study. Body mass index (BMI), IOP measurements, and retrobulbar CDU examination were performed on all individuals 6months before and after bariatric surgery.ResultsThe preoperative mean BMI value was 48.82.27kg/m(2), and mean IOP value was 18.2 +/- 2.06mmHg. At 6months postoperatively, mean BMI and IOP were 36.28 +/- 5.41kg/m(2) and 16.1 +/- 1.81mmHg which was statistically significantly lower than the preoperative measurements (p<0.001). In the comparison of pre- and postoperative orbital CDU value, the preoperative OA PSV (30.16 +/- 5.31cm/s) and OA EDV (10.93 +/- 3.04) values were significantly lower than the postoperative OA PSV (36.21 +/- 5.56) and OA EDV (12.84 +/- 3.38) values (p<0.001 and p<0.05, respectively). A significant correlation was determined between BMI and IOP (r=-0.443; p<0.05).Conclusions Decrease in body weight resulting from bariatric surgery performed on morbid obese patients causes alterations in both IOP and retrobulbar hemodynamics. Morbidly obese patients who undergo bariatric surgery have statistically significantly lower IOP values and increase in OA Doppler parameters (PSV, EDV) than in the preoperative period, which reflects a better retrobulbar and ocular blood flow.
