| Summary: | <b>Background:</b> This study aims to evaluate changes in the central retina in patients with type 2 diabetes mellitus (T2DM) undergoing uncomplicated small incision cataract surgery with or without pseudoexfoliation syndrome (PEXS) using optical coherence tomography angiography (OCTA). <b>Methods:</b> In this prospective, longitudinal study, 67 T2DM patients underwent cataract surgery. Twelve of them had PEXS. All parameters were measured at two time points. Macular 3 × 3 mm and 6 × 6 mm OCTA images were obtained. All data were analyzed using R statistical software (version 4.4.1). <b>Results:</b> Parafoveal vascular density (VD) in the superior capillary plexus and the deep capillary plexus increased in the non-PEX group. There was an increase in VD in perifoveal vascular density in the deep capillary plexus in both groups. Three months after cataract surgery, changes in perifoveal vascular density in the deep capillary plexus increased in both groups and were significant. <b>Conclusion:</b> Perifoveal vascular density in the deep capillary plexus showed a significant increase in VD, regardless of the presence of PEXS. Parafoveal VD in the deep and superficial capillary plexuses appeared to be sensitive primarily in non-PEXS patients, with a notable increase observed in these areas three months after surgery. |
