摘要

Purpose

Recurrent retinal detachment (re-RD) after rhegmatogenous retinal detachment (RRD) surgery is associated with poor visual outcomes. This retrospective study evaluated the incidence and risk factors for re-RD following primary 25-gauge pars plana primary vitrectomy (25G-PPV).

Study design

Retrospective observational study

Methods

Consecutive patients who underwent initial 25G-PPV at Fujita Health University Hospital between January 2011 and March 2019 were included. After applying exclusion criteria, preoperative and surgical factors were obtained from medical records. Patients were categorized into re-RD and initial reattachment groups. Univariate analysis was used to identify factors associated with re-RD, followed by multivariate analysis of significant variables.

Results

Among 1399 eyes, the mean age was 56.5±11.0 years. The re-RD and reattachment groups included 89 and 1310 eyes, respectively. The initial reattachment rate was 93.2%. Significant differences were observed between macular detachment and inferior retinal break (RB). The odds ratios of macular detachment and inferior RB in the re-RD group were 1.70 (95% confidence interval [CI] 1.05–2.79) and 2.26 (1.40–3.61), respectively.

Conclusion

The initial reattachment rate with 25G-PPV was 93.2%. The re-RD group showed higher rates of macular detachment and a higher proportion of inferior RB, identified as risk factors for re-RD. RD due to inferior RB with macular detachment may require vitrectomy combined with buckling.
