Introduction: To compare the results and complication rates of a 25-gauge pars plana vitrectomy (PPV) with gas tamponade for rhegmatogenous retinal detachment (RRD) between experienced and inexperienced surgeons.
Materials and Methods: This is a retrospective comparative consecutive case series study of patients with uncomplicated RRD treated with 25g PPV with gas tamponade. Patients were divided into 2 groups: In experienced surgeon group (ESG) the procedure was performed by an experienced vitreoretinal surgeon and in inexperienced surgeon group (ISG) the procedure was performed by 2 inexperienced surgeons. Anatomical and functional results and complication rates were compared between the two groups.
Results: 216 eyes were included in the study. In the ESG (106 eyes), the single operation success rate was 94.3%, and the final success rate was 100%. In the ISG (110 eyes), the single operation success rate was 93.6%, and the final success rate was 100.0%. The difference in single surgery success rate between groups was not statistically significant (P = 0.828). The mean postoperative BCVA improvement was 0.348 decimal in ESG and 0.405 decimal in ISG (P = 0.234). The difference in complication rates between groups was not significant.
Conclusions: A 25g PPV with gas tamponade for treatment of RRD yields excellent anatomical results and improvement in BCVA. With good technique and use of modern vitrectomy machines and instruments, even inexperienced surgeons can achieve high single operation success rate, suggesting a short learning curve. The complication rate is comparable between experienced and inexperienced surgeons.
