PURPOSE To evaluate the outcomes of pars plana vitrectomy and silicone oil injection for the treatment of infectious endophthalmitis. METHODS 35 cases of endophthalmitis secondary to phacoemulsification (20 patients), trabeculectomy (8 patients), perforating trauma (2 patients), trauma (2 patients), corneal transplantation (1 patient), vitrectomy (1 patient) and corneal ulceration (1 patient)...

OBJECTIVE To investigate the outcome of rhegmatogenous retinal detachment repair at Vitreoretinal unit of Jinnah Post Graduate Medical Centre Karachi in year 2014. METHODS One hundred and three eyes of one hundred and three patients, who underwent three ports parsplana vitrectomy + band + silicone oil, three ports pars plana vitrectomy + silicone oil, three ports pars plana vitrectomy + C3F8 ...

PURPOSE To evaluate the efficacy of vitrectomy combined with intravitreal injection of triamcinolone acetonide (IVTA) and macular laser photocoagulation for the treatment of nontractional diabetic macular edema (DME) refractory to anti-vascular endothelial growth factor (VEGF) therapy. METHODS Twenty-eight eyes from 28 subjects who were diagnosed with nontractional DME refractory to three or ...

Purpose The present study aimed to examine changes in optic nerve head (ONH) blood flow autoregulation in 4 quadrants (superior, nasal, inferior, and temporal) with decreased ocular perfusion pressure (OPP) during vitrectomy in order to determine whether there is a significant difference of autoregulatory capacity in response to OPP decrease at each ONH quadrant. Methods This study included 2...

PURPOSE To evaluate management options for acutely symptomatic stage I macular holes, and vitrectomy with intraocular gas tamponade for advanced stage I macular holes. METHODS Retrospective noncomparative study. SETTING Clinical practice. STUDY POPULATION Acutely symptomatic stage I macular holes. MANAGEMENT OPTIONS: (I) spontaneous resolution with observation -7 eyes; (II) stage I holes ...

PURPOSE To describe the results of a pars plana vitrectomy, combined with phacoemulsification, using a sutureless, superotemporal, clear corneal incision for patients with a macular hole. METHODS This study reviewed the records of 22 patients (22 eyes) who underwent a phacoemulsification with the insertion of an acrylic intraocular lens, using a 3.2 mm superotemporal clear corneal incision an...

BACKGROUND To assess the occurrence and magnitude of refractive change in pseudophakic eyes undergoing 20 gauge pars plana vitrectomy without scleral buckling and to investigate possible aetiological factors. METHODS Retrospective case note review of 87 pseudophakic eyes undergoing 20 gauge pars plana vitrectomy for a variety of vitreo-retinal conditions over a three-year period. Anterior cha...

Endophthalmitis following pars plana vitrectomy is a very uncommon cause of endophthalmitis. Cases reported over the last decade show a decrease in incidence over time. To optimize visual outcome, early diagnosis and treatment are essential. In this review we report a summary of the incidence of endophthalmitis following vitrectomy, various risk factors for their occurrence, the microbiological...

Every cataract surgeon should have a game plan for when and how to perform an anterior vitrectomy following posterior capsule rupture. This chapter will review the goals, the indications, and the techniques of an anterior vitrectomy. Understanding and mentally rehearsing these strategies will better prepare cataract surgeons to make correct decisions amidst the stress of an unexpected complicat...

By using a small air bubble that fills about two thirds of the anterior chamber the erect image of the fundus of the aphakic human eye can be visualised clearly during vitrectomy, enabling the surgeon to operate without the need for vitrectomy lenses. The refractive power of the human aphakic eye is calculated here and the image site and size are presented.
