Body mass index (BMI), macular thickness (whole, fovea, parafovea and perifovea), macular vascular density (VD) in superficial capillary plexus (whole, fovea, parafovea and perifovea), and macular vascular density in deep capillary plexus (whole, fovea, parafovea and perifovea) were measured before and 3 months after bariatric surgery.Results: The BMI was significantly reduced postoperatively to 43.75± 4.4 kg/m2 compared to the preoperative results, 55.31± 5.1 kg/m2 (p 0.05). Significant correlations were detected between the BMI changes and changes in different macular parameters.Conclusion: Bariatric surgery showed significant effect on certain indices in macular thickness and macular vascular density, especially in the deep capillary plexus. Therefore, OCTA is considered a valuable tool to assess the short-term changes in macular microcirculation following significant weight reduction.Keywords: bariatric surgery, optical coherence tomography angiography, OCTA, macular thickness, macular vessel density
