The pooled risk of second surgery for primary vitrectomy was<br />
13.3% (196/1,465), for pneumatic retinopexy 25.2% (484/1,919), and<br />
for segmental buckling 9.1% (170/1,854). The pooled risk of PVR<br />
after vitrectomy was 5.3% (76/1,417), after pneumatic retinopexy<br />
was 6.5% (111/1,697), and after scleral buckling 0.9% (17/1,702)<br />
