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 describe a 42-year-old man, a known case of Bietti crystalline dystrophy who underwent surgery for unilateral full thickness macular hole. CASE REPORT Clinical features, color fundus photographs, and optical coherence tomography, electroretinography, and electrooculography findings of the patient are reported. His visual acuity improved from counting fingers to 20/50 after pars pla...
PURPOSE To assess the incidence rate of endophthalmitis after 25-gauge pars plana vitrectomy and to compare it with the endophthalmitis rate after 20-gauge pars plana vitrectomy. DESIGN Retrospective, interventional, comparative cohort study. PARTICIPANTS Eight thousand six hundred one consecutive pars plana vitrectomy surgery patients. METHODS Surgeries performed at a single institution ...
A low-cost automated vitrectomy machine was developed locally by the Department of Medical Physics and Engineering at Edinburgh University. The machine uses disposable handpieces, and has proved to be user-friendly, reliable, and efficient for anterior segment vitrectomy and, for selected patients, for posterior segment vitrectomy. The construction and mechanics of the machine are described. Si...
PURPOSE To report a case of endophthalmitis following 25-gauge transconjunctival sutureless vitrectomy. DESIGN Observational case report. METHODS An 87-year-old male who underwent sutureless 25-gauge vitrectomy developed unilateral endophthalmitis. Vitreous culture revealed Staphylococcus coagulase-negative bacteria. He was subsequently treated with intravitreal antibiotics and oral prednis...
AIM To describe the rate of fellow eye vitrectomy for proliferative diabetic retinopathy in an inner city population. METHODS Retrospective interventional case series. Medical and surgical records of 434 consecutive eyes of 358 patients undergoing primary diabetic vitrectomy in an inner city institutional practice were reviewed. Kaplan-Meier statistical analysis was employed to evaluate the r...
The aim of this prospective study was to determine the possible influence of the silicone oil tamponade after vitrectomy on the early intraocular pressure (IOP) elevation, which is a major risk factor for developing secondary glaucoma in patients with vitreal and retinal proliferative changes. The research included 110 patients which were allocated in three groups according to the medical histo...
PURPOSE To evaluate the efficacy of the inverted internal limiting membrane (ILM) flap technique in vitrectomy for macular hole (MH) with retinal detachment (RD) compared with vitrectomy using ILM peeling. METHODS A retrospective case series study was performed. Twenty-two eyes of 22 patients who underwent vitrectomy for MH with RD and followed-up more than 12 months after the surgery were in...
This is a case of Valsalva retinopathy during the season annual transboundary haze pollution in Sarawak. A 22-year-old man with no known medical illness developed sudden onset painless visual acuity loss preceded by persistent cough. Left eye fundus showed dense preretinal haemorrhage covering optic disc extendinginferiorly breakthrough vitreous haemorrhage. The patient underwent pars plana vit...
