PURPOSE To assess the risks of vitrectomy for the removal of primary and secondary vitreous opacities. DESIGN Retrospective, nonrandomized, interventional case series. METHODS We reviewed the results of 116 consecutive cases of vitrectomy for vitreous floaters. Eighty-six cases were primary and 30 cases were secondary floaters. Main outcome measures were the incidence of iatrogenic retinal ...
Introduction: The purpose of this work is to study the efficacy preoperative intravitreal administration bevacizumab as an adjunct vitrectomy in patients with Proliferative Diabetic Retinopathy (PDR). Methods: This retrospective comparative was performed on 118 eyes (118 patients) proliferative diabetic retinopathy (PDR), which underwent surgery at Department Eye Disease Zarifa Aliyeva National...

 Introduction: Surgical approach in vitreous hemorrhage (VH) secondary to diabetic retinopathy remains the procedure of choice for non-clearing VH. However, most appropriate timing vitrectomy is yet be defined. With improvements surgical techniques, it reasonable operate on such patients that have no spontaneous improvement.
 Objective: To compare characteristics between groups who u...
PURPOSE Scleral buckling is currently used in addition to vitrectomy for the treatment of pseudophakic retinal detachment (PRD) to better support the vitreous base and better visualisation of the periphery. AIMS The aims of this study are to evaluate (1) whether the combination of 20 G vitrectomy and scleral buckling is superior to 20 G vitrectomy alone (control) (confirmatory), and (2) wheth...
PURPOSE To investigate whether vitreous and aqueous humor concentrations of vascular endothelial growth factor (VEGF) predict postoperative complications after vitrectomy for proliferative diabetic retinopathy (PDR). METHODS Sixty eyes of 52 patients with PDR who underwent vitrectomy were enrolled. Vitreous and aqueous humor were obtained from eyes with PDR during primary vitrectomy and the l...
Malignant glaucoma is a rare secondary glaucoma classically occurring after intraocular surgery in eyes with primary angle closure. Pars plana vitrectomy is reserved for the treatment of malignant glaucoma when medical and laser treatment fail. The primary aim of surgery is the removal of the anterior vitreous to reduce resistance to aqueous flow into the anterior chamber. In phakic eyes, conve...
Purpose We report a case of ophthalmomyiasis interna successfully removed in toto with pars plana vitrectomy. Observations An 84-year-old woman with recent close contact with lambs presented with a new floater. Examination revealed subretinal tracks pathognomonic for ophthalmomyiasis and a larva suspended in the vitreous. The larva was successfully removed in toto with pars plana vitrectomy b...
Dear Editor, Pars plana vitrectomy (PPV) using the 27-gauge transconjunctival approach is the last frontier of small gauge vitrectomy. Only 1 paper has been published so far describing the use of 27-gauge vitrectomy in a limited number of cases, including epiretinal membranes, idiopathic macular holes, diabetic vitreous haemorrhages, a vitreous biopsy for presumed vitreoretinal lymphoma and a f...
PURPOSE To investigate the vitreous and plasma levels of vascular endothelial growth factor (VEGF) in patients with proliferative diabetic retinopathy (PDR) and to determine whether they predict a disease prognosis after primary vitrectomy. METHODS Fifty patients (50 eyes) with PDR who underwent pars plana vitrectomy (PPV) and 56 healthy controls (56 eyes) were enrolled in this retrospective ...
