BackgroundTo evaluate the surgical outcome for management of giant retinal tear (GRT) more than 180° by combined pars plana vitrectomy (PPV), encircling scleral buckle, 360° Laser endophotocoagulation, and silicon oil tamponade.MethodsThis was a Prospective, interventional case series study. Twenty four eyes of 23 patients suffering from GRT more than 180° underwent PPV combined with encircling scleral buckle and 360° laser retinopexy of the peripheral retina followed by silicon oil tamponade. All patients were followed up for at least six months.ResultsComplete anatomical success (retinal attachment after silicone oil removal) was achieved in 20 (83.3%) eyes at the end of follow-up, while incomplete anatomical success (retinal redetachment under or after removal of silicon oil) occurred in four (16.7%) eyes. At the end of follow-up period (mean of 13.7 months + 6.5), improvement of best-corrected visual acuity was achieved in 22 (91.7%) eyes. Preoperative best-corrected visual acuity ranged from HM to 0.15 while postoperative visual acuity ranged from HM to 0.9. Retinal slippage did not occur in any case. Additionally, removal of the clear crystalline lens in phakic eyes was not necessary in the primary intervention.ConclusionsGRT more than 180° can be effectively treated with PPV coupled with encircling scleral buckle, 360° laser retinopexy and silicon oil tamponade with no incidence of retinal slippage. In this complex procedure, concurrent encircling buckle the primary intervention may contribute to high chance of success.

Repeated IVB injection could provide a long-term benefit for the treatment of diffuse diabetic macular edema. Performing macular grid photocoagulation once only 3 weeks subsequent to the initial IVB injection might provide a longer disease-free intervals and reduces the burden of more frequent injections.

For selected cases of inferior retinal detachment in silicone oil-filled eyes, supplemental scleral buckling could be as effective as a second vitreoretinal surgery. Scleral buckling could offer a faster, less invasive, and better economic alternative to repeated vitreoretinal surgery for treatment of such cases.

BackgroundThe purpose of the current study is to evaluate the surgical outcome for rhegmatogenous retinal detachment (RD) associated with Behçet’s disease (BD).MethodsThe current retrospective study included all patients operated for rhegmatogenous RD associated with BD in our institution from June 2007 to June 2012. Surgical repair was done either by scleral buckling (SB) or pars plana vitrectomy (PPV) according to the topography and clinical criteria of the detachment.ResultsThe current study included 7 eyes of 7 patients (6 males and one female). The mean age was 34.3 ± 4.9 years and all patients showed systemic features of BD. In 3 eyes, intravitreal triamcinolone acetonide (IVTA) was injected within 8 weeks prior to the occurrence of rhegmatogenous RD. Five eyes were treated with SB (segmental buckle in 4 cases and encircling buckle in one case) and 2 cases were treated by PPV. One case was initially treated by SB but showed recurrence of RD which was surgically repaired by PPV with successful closure of the retinal break. The retina was successfully reattached in all cases at the end of follow up period (22.0 ± 6.7 months).ConclusionsRhegmatogenous RD in BD can be effectively treated by scleral buckling in selected cases and PPV in more complex cases. Intravitreal injections may be a precipitating factor for rhegmatogenous RD.
