BACKGROUND AND OBJECTIVE To evaluate the efficacy and safety of the pars plana Ahmed glaucoma valve (New World Medical, Inc., Rancho Cucamonga, CA) implant combined with pars plana vitrectomy and panretinal photocoagulation for the management of neovascular glaucoma in patients with vitreous hemorrhage. PATIENTS AND METHODS The records of 18 eyes of 17 consecutive patients with neovascular gl...

PURPOSE To characterize short-term changes induced by pars plana vitrectomy on anterior segment depth and lens thickness by means of high-frequency ultrasound biomicroscopy. METHODS We undertook a prospective case series study on consecutive patients referred for pars plana vitrectomy as the sole procedure in our institution between 2005 and 2007. Twenty-eight eyes of 28 patients undergoing p...

OBJECTIVE To evaluate the efficacy and results of pars plana vitrectomy with endotamponade for retinal detachments caused by necrotizing retinitis in HIV patients. MATERIAL AND METHOD The data of patients with HIV-related retinal detachment who underwent pars plana vitrectomy with silicone oil or gas endotamponade between January 2003 and June 2005 were retrospectively reviewed The outcome me...

PURPOSE To evaluate the efficacy of combination pars plana vitrectomy, endoscopic peripheral panretinal photocoagulation, and endocyclophotocoagulation (ECP) as compared with standard care in patients with neovascular glaucoma. METHODS This age-matched case-controlled retrospective series of 54 eyes compared the clinical outcomes between a consecutive series of combination pars plana vitrecto...

BACKGROUND The purpose of this study was to investigate lamellar macular hole formation in six patients after rhegmatogenous retinal detachment repair. METHODS A retrospective review of medical records of patients who underwent primary pars plana vitrectomy for rhegmatogenous retinal detachment repair was performed. Optical coherence tomography characteristics and best-corrected visual acuity...
