Abstrakt: Purpose: The choice of surgical method for rhegmatogenous retinal detachment (RRD) may have a significant impact on the retina. In this study, we aimed to compare retinal function and structure after scleral buckling (SB) and phacovitrectomy (phaco-PPV) for macula-on RRD. Patients and Methods: This cross-sectional study included patients who underwent anatomically successful repair of macula-on RRD managed with SB (n=35) and phaco-PPV (n=35) between 2019– 2023. All participants were examined within 6– 20 months of surgery to evaluate the retinal structure using spectral domain optical coherence tomography (SD-OCT) and vessel density (VD) by OCT angiography (OCTA). Best-corrected visual acuity (BCVA) and microperimetry (MP) tests were used to assess the retinal function. Results: Analysis of the microvascular network with OCTA between eyes after surgery and healthy eyes showed a decrease in VD. Significant changes in the superficial vascular plexus (SVP) and deep vascular plexus (DVP) were observed only in eyes after SB surgery (p < 0.001 and p=0.02, respectively). Analysis of retinal function assessed by MP showed a significant decrease (p< 0.05) in retinal sensitivity after phaco-PPV (24.81± 2.25 dB) and SB (24.18± 2.14 dB) operations compared to the healthy control group (25.97 ± 1.51 dB), whereas postoperative BCVA showed no differences (p> 0.05). Conclusion: Changes in retinal sensitivity were accompanied by impairment of the microvascular network in the eyes after SB and phaco-PPV surgeries due to macula-on RRD. Disorders were more pronounced in eyes following SB surgery, possibly secondary to mechanical stress. [ABSTRACT FROM AUTHOR]
