Abstract
PURPOSE: To assess changes in surgical decisions and outcomes of rhegmatogenous retinal detachment (RRD) during the COVID-19 pandemic at a tertiary center in Taiwan. METHODS: Patients undergoing pars plana vitrectomy (PPV) or scleral buckling (SB) for primary RRD during Taiwan's first wave of domestic COVID-19 cases surge between May and July 2021 (COVID cohort, n = 100) were compared to controls in the closest pre-COVID year, 2019 (pre-COVID cohort, n = 121). RESULTS: The COVID cohort had significantly worse RRD presentation, received more PPV (alone or combined with SB (PPV + SB)) and less SB alone, and had comparable single-surgery anatomic success (SSAS) rates. In patients who underwent PPV, more underwent PPV + SB instead of PPV alone. The decision to combine SB in PPV surgery was significantly affected by the COVID pandemic (odds ratio [OR], 3.1860 [95% confidence interval (CI), 1.1487-8.8361]). However, a shorter duration of symptoms before the first presentation (0.9857 [95% CI, 0.9720-0.9997]) was the only factor related to SSAS, whereas the surgical method had no association. The SSAS rate remained close to or over 90% in patients with a duration of symptoms before surgery ≤4 weeks but dropped to 83.3% in patients with duration >4 weeks. CONCLUSION: During the COVID-19 pandemic, worse RRD presentations led to a shift in preference for PPV over SB alone as the primary surgery. The pandemic affected surgeons' decision to combine SB during PPV. Nevertheless, SSAS was only associated with the duration of symptoms but not with surgical methods.
