Abstract
Purpose: :
To compare the incidence of proliferative vitreoretinopathy (PVR) in patients with rhegmatogenous retinal detachment (RRD) and PVR treated by pars plana vitrectomy (PPV) and silicone oil tamponade without or with encircling scleral buckling (ESB) procedure.
Methods: :
Retrospective study. Main outcome measures were anatomic success rates, preoperative and postoperative visual acuity and complications. We reviewed the files of two groups of patients affected by RRD and associated PVR. Group A (22 patients) was treated by PPV and silicone oil injection without (ESB). Group B (21 patients) was treated with PPV, silicone oil tamponade with ESB.
Results: :
The proliferation incidence rate is respectively 27,7% in group A and 33,3% in group B; the retinal redetachment rate is not statistically significant between the two groups. Final visual acuity was 1/100 or better in 16 patients (72,7%) of group A and in 7 patients (80,9%) of group B, hand movement in 3 patients (13,6%) of group A and in 2 patients (9%) of group B, finger counting in 2 patients (9%) of group A and in 2 patients (4,5%) in group B. One patient in group B developed motility defect
Conclusions: :
Main outcome measures in the two groups were not statistically significant by the chi-square test. Adjunctive ESB procedure to PPV for the treatment of RRD with PVR brings no additive advantage and can increase ocular complications.
