Success Rates of Vitrectomy in Treatment of Rhegmatogenous Retinal Detachment

Abstract

Aim. To investigate the anatomical success rates of pars plana vitrectomy (PPV) after primary rhegmatogenous retinal detachment (RRD). Methods. This retrospective study was conducted between December 2008 and October 2014 at Nagasaki University Hospital. The preoperative data recorded included the lens status, location of the retinal tear, whether a tear was visualized, presence of multiple tears, macula status, presence of peripheral lattice retinal degeneration, and best-corrected visual acuity (BCVA). The primary outcome measures were anatomical (primary and final) and functional success (visual acuity better than 6/60). Results. This study evaluated 422 eyes of 411 patients with a mean age of 57.7 ± 11.2 years. The single-operation reattachment rate (primary anatomical success) was 89.8%. The final anatomical success rate was 100% after 2–6 operations (mean = 3.14 ± 1.03). Functional success rate after the primary reattachment operation was 96.7%, while it was 97.2% at the end of the follow-up. Multiple logistic regression analysis of the possible risk factors for the primary anatomical failure showed a significant relation with the 25 G instruments (P = 0.002) and the presence of multiple tears (P = 0.01). Conclusion. The primary anatomical success of PPV for primary uncomplicated RRD was 89.8% and the final anatomical success rate was 100%.

Predictive Risk Factors for Retinal Redetachment Following Uncomplicated Pars Plana Vitrectomy for Primary Rhegmatogenous Retinal Detachment

“…Previous studies have published success rates of PPV for the repair of primary RRD, ranging from 82.4% to 93.5% [ 2 , 14 , 15 , 16 ]. Known risk factors include proliferative vitreoretinopathy (PVR) and giant retinal tears, which are associated with a higher incidence of redetachment [ 17 ].…”

Internal limiting membrane peel: Does it change the success rate of primary vitrectomy without belt buckle in rhegmatogenous retinal detachments?

“…[20212223] In phakic patients, the difficulties/inadequacy in the base excision, because of fear of lens touch, the success rates are reported in the range of 86%–92%. [24] An improved success rate of 96.3% was observed by Hamauda Ghoraba et al . by use of belt buckle.…”

Alginate- and Hyaluronic Acid–Based Hydrogels as Vitreous Substitutes: An In Vitro Evaluation

“…1 However, even modern tamponade materials have not significantly improved the primary reattachment rate in the last 30 years. [2][3][4][5][6] In particular, they do not provide a satisfactory response to multiple breaks at different sites, the challenges of proliferative vitreoretinopathy (PVR) or persistent hypotension.…”
