Background
To determine the preoperative factors associated with selecting scleral buckling (SB) or pars plana vitrectomy (PPV) to treat rhegmatogenous retinal detachments (RRDs) in the era of microincision vitrectomy surgery.
Methods
A nationwide, multicenter, observational study in the Japan Retinal Detachment Registry was done. From February 2016 to March 2017, 3446 cases were registered, and 3219 among them were analyzed. The factors related to the patient or surgeon were selected; the surgeon’s factor included years of experience, number of cases registered, and current activity. The odds ratio (OR) for factors associated with SB or PPV was estimated by a mixed logistic regression model.
Results
SB was selected in 24.2% (779/3219), PPV was in 71.5% (2238/3219), and PPV+SB was in 6.3% (202/3219). Multivariate analysis showed that age [< 70 years old, OR 4.27, 95% confidence interval (CI) 2.34–7.79, P < 0.001], visual acuity [1.0+ (OR 7.41, 95% CI 3.47–15.82, P < 0.001)], pseudo-phakia (OR 4.83, 95%CI 2.11-10.56, P < 0.001), retinal tear (OR 6.92, 95% CI 4.83–9.92, P < 0.001), breaks at/near the vitreous base (OR 8.07, 95% CI 3.50–18.62, P < 0.001), 90+° retinal tear (OR 108.24, 95% CI 7.44–1574.34, P < 0.001), and number of breaks 4+ (OR 3.15, 95% CI 1.95–5.09, P < 0.001), were significantly associated with selecting PPV over SB. The surgeons’ activity defined as the number of cases experienced during the registry period was related to the selection of PPV (OR 3.83, 95% CI 2.11–6.93, P < 0.001).
Conclusions
The choice of PPV for the RRD was associated not only with patients’ preoperative factors but also the surgeon’s activity. Active surgeons selected PPV more than SB.
