RESUMO
PURPOSE: To investigate whether intravitreal antiviral injection (IAI) during vitrectomy reduces the postsurgical retinal detachment (RD) rate and improves the visual prognosis of patients with acute retinal necrosis (ARN). METHODS: This retrospective cohort study included ARN patients treated at a tertiary hospital between January 2013 and December 2020. Patients who underwent pars plana vitrectomy (PPV) alone or combined with intraoperative IAI were classified in PPV-only group and PPV + IAI group, respectively. The incidence of postsurgical RD and the best corrected visual acuity (BCVA) between the groups was compared. A multivariate Cox hazard analysis was employed to explore the risk factors of postsurgical RD. A multivariate logistic regression analysis was applied to assess the impact of intraoperative IAI on preventing severe vision loss (SVL). RESULTS: Fifty-seven eyes with ARN with a median follow-up of 18.5 months were included in the study. There was no significant association between intraoperative IAI during vitrectomy and a reduced risk of postsurgical RD (hazard ratio [HR], 2.65; 95% CI, 0.71-9.89) or SVL at the 6-month follow-up visit (odds ratio [OR], 0.92; 95% confidence interval [CI], 0.25-3.35). Better baseline best-corrected visual acuity (BCVA) was identified to associate with a higher risk of postsurgical RD (HR, 0.33; 95% CI, 0.14-0.81) and a lower risk of SVL at 6 months (OR, 2.28; 95% CI, 1.10-4.89). CONCLUSION: We did not observe a significant effect of intraoperative IAI on the anatomic and visual outcomes of ARN patients in this study. Intraoperative IAI may not be a necessary treatment option for ARN patients who receive vitrectomy.

INTRODUCTION: The aim of this study was to compare the long-term outcomes of conventional scleral buckling (CSB), modified scleral buckling (MSB), and scleral encircling (SE) in the treatment of rhegmatogenous retinal detachment and identify factors influencing the outcomes. METHODS: This comparative, retrospective cohort study assigned patients to CSB, MSB, and SE groups. The follow-up was 12 months, and the reattachment rate, complication rate, visual acuity, number of newly discovered tears during surgery, and changes in diopters were compared among the three surgeries. Influential factors on anatomical and functional reattachment were identified. RESULTS: There were no significant differences in the primary reattachment rate, overall complication rate, or best corrected visual acuity at 6 or 12 months among the three groups. The MSB group had a higher number of newly discovered tears during surgery compared with the other two groups. At 12 months of post-surgery, the SE group displayed the greatest change of diopter, whereas the MSB group showed the least change. The surgical approach did not influence the primary reattachment rate. Long-term visual outcomes were influenced by factors including sex, preoperative visual acuity, macular status, and duration of symptoms. CONCLUSION: MSB is an effective method for treating rhegmatogenous retinal detachment. Its advantages include the ability to identify smaller tears and induce minimal changes in diopter.
