Scleral buckling versus vitrectomy for young japanese patients with rhegmatogenous retinal detachment in the era of microincision surgery: real-world evidence from a multicentre study in Japan.

Abstract

To evaluate real-world evidence for young Japanese patients with rhegmatogenous retinal detachment (RRD) by retrospectively examining surgical procedures and clinical outcomes in the Japan Clinical Retina Study group. This was a multicentre retrospective study of the medical records of 562 young patients (384 males and 178 females; mean age: 33.0±11.8years) who had been diagnosed with RRD and who underwent surgical procedures in participating centres during the period between April 2013 and August 2016. The selected surgeries were scleral buckling (SB) for 295 eyes (49.7%) and pars plana vitrectomy (PPV) for 262 eyes (44.1%). Between the two surgical procedures, there was no significant difference in the primary anatomical reattachment rate (PARR, SB=92.2%, PPV=93.9%); improvements in vision were noted in both groups. The incidences of proliferative vitreoretinopathy and cataract formation within 1year of PPV were 2.3% (p=0.0047) and 6.5% (p=0.0005), whereas they were 0% and 1.0% in the SB group, respectively. Scleral buckling (SB) and PPV were chosen with almost equal frequency for young patients with RRD. Clinical outcomes for SB and PPV exhibited a similar PARR. The incidence of cataract formation after PPV may constitute an important limitation of the procedure.
