Abstract

Purpose: To identify the risk factors associated with recurrent retinal detachment after primary pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD).

Methods: A retrospective chart-review was carried out on 107 cases of primary PPV for RRD performed by a single surgeon. Preoperative and intraoperative characteristics were analyzed to identify the risk factors associated with recurrence of retinal detachment after the primary surgery.

Results: 54.2% of the patients (58 out of 107) were phakic and 58.9% (63 out of 107) had macula off state. 22.4% (24 out of 107) of patients had inferior break. 10.3% (11 out of 107) had preoperative proliferative vitreoretinopathy (PVR) grade higher than A or B. 57.0% (61 out of 107) of the patients performed drainage retinotomy during the surgery.<br /> Retinal reattachment was achieved with single operation in 86.9% (93 out of 107) and 14 cases (13.1%) had retinal redetachment. Factors significantly associated with redetachment were inferior breaks (p=0.049), and PVR grade higher than A or B (p=0.016). 25% (6 of 24) of the RRD with inferior break had retinal redetachment and 36% (4 of 11) of the RRD with PVR grade higher than A or B had retinal redetachment.

Conclusions: Primary PPV for RRD has relatively low redetachment rate following the initial procedure. The risk factors for postoperative failures include preoperative inferior breaks, and PVR grade higher than A or B. Future improvements of the technique will have to focus on these risk factors to reduce failure rate.
