Purpose To introduce a hybrid wide-angle viewing-endoscopic vitrectomy, which we have reported, using a 3D visualization system developed recently. Subjects and methods We report a single center, retrospective, consecutive surgical case series of 113 eyes that underwent 25 G vitrectomy (rhegmatogenous retinal detachment or proliferative vitreoretinopathy, 49 eyes; epiretinal membrane, 18 eyes...

We evaluated the effect of intravitreal bevacizumab (IVB) injection before pars plana vitrectomy (PPV) on intravitreal hemorrhage (VH) during and after vitrectomy for postoperative the first day and the first month in pseudophakic patients with proliferative diabetic retinopathy (PDR). This retrospective study was performed on 44 eyes of 44 patients who underwent vitrectomy for PDR. Patients we...

AIMS To examine possible benefits of intravitreal bevacizumab (IVB) pretreatment in vitrectomy for severe diabetic retinopathy. METHODS A comprehensive literature search was performed using the Cochrane Collaboration methodology to identify randomised controlled trials and comparative studies of vitrectomy with or without IVB pretreatment for severe or complicated diabetic retinopathy. Meta-a...

PURPOSE The outcome of vitrectomy combined with phacoemulsification and intraocular lens implantation (PEA+IOL) for diabetic macular edema was evaluated. METHODS Included in this study were 31 patients (42 eyes) with clinically significant diabetic macular edema, in whom posterior vitreous detachment was not observed. Pars plana vitrectomy combined with PEA+IOL was performed on 15 eyes. Sixte...

BACKGROUND AND OBJECTIVE Vitrectomy markedly alters the intraocular milieu, which can then affect the physiology of the retina and choroid. This study investigates whether vitrectomy also alters ocular blood flow as determined by laser speckle flowgraphy (LSFG). PATIENTS AND METHODS Twenty eyes of 20 patients that underwent vitrectomy for idiopathic macular hole or epiretinal membrane were st...

PURPOSE To compare the efficacy of the transconjunctival releasable suture technique for pars plana vitrectomy using 23-gauge (23G) instruments versus the conventional 20-gauge (20G) technique. METHODS A retrospective and interventional case series was consecutively performed for 199 eyes of the 192 patients that were a part of this study. Clinical data were reviewed retrospectively regarding...

PURPOSE To compare the surgical results of vitrectomy and scleral buckling for uncomplicated superior retinal detachment caused by flap tears. METHODS Included in the study were 225 patients (225 phakic eyes) undergoing primary surgery by three surgeons between January 1990 and December 1996 for superior retinal detachment caused by flap tears (138 eyes by scleral buckling, 87 eyes by vitrect...

purpose: to determine factors that affect and predict final visual acuity, retinal attachment, and ocular survival after open-globe injuries. methods: one-hundred sixteen eyes with open globe injuries were evaluated longitudinally from september 2001to february 2004. age, sex, involved eye, best corrected visual acuity (bcva), afferent pupillary defect (apd), size and location of laceration, ca...

the purpose of this study was to compare the anatomic and visual outcome of primary vitrectomy with scleral buckling in patients with retinal detachment following cataract surgery. fifty-six consecutive patients with retinal detachment after cataract surgery were randomly assigned to two treatment groups: standard scleral buckling and standard three-port deep vitrectomy. successful treatment wa...
