Outcomes of Scleral Buckling Surgery in Rhegmatogenous Retinal Detachment: An Iranian Experience

Abstract Purpose: To evaluate the anatomical and visual outcomes of SB surgery in patients with rhegmatogenous retinal detachment (RRD) and investigate the impact of pre- and intraoperative factors on final surgical and functional success rates Methods: In this retrospective study, medical records from all patients with RRD for whom SB surgery was performed between March 2015 and October 2019 in Torfe Eye Hospital in Tehran, Iran, were included. Results: A total of 80 patients (54 males and 27 females) with a mean (±SD) age of 45 (±15; ranging from 19 to 80) underwent SB surgery. Primary and final retinal reattachment rates were 73.3% and 91.3%, respectively. The mean (±SD) pre- and postoperative best-corrected visual acuities were 1.04 (±0.8) and 0.73 (±0.58) LogMAR, respectively (P-value<0.001). Eyes with inferior RRDs had less favorable success rates than those with non-inferior RRDs (80.0% vs. 93.8%, respectively, p=0.003). The preoperative macula situation status (i.e., off vs. on) was another factor of influence on the surgical success rate (86.1% and 95.4% in macula-off and -on groups, respectively, p=0.023) Conclusion: SB is an effective treatment option for rhegmatogenous retinal detachment. Our results clearly showed that the prognosis of patients with an intact macula is better than the others.
