purpose : to evaluate the efficacy of autologous plasmin in pediatric vitrectomy and to report the anatomic outcomes of autologous plasmin assisted pediatric vitrectomy methods : in an interventional prospective study, thirty-four pediatric patients with vitreoretinal disorders who needed vitrectomy during 2008 to 2010, included in the study. the patients were divided into two groups: the retin...
PURPOSE Various immune mediators are hypothesized to have important roles in the pathogenesis of vitreoretinal B-cell lymphoma, although the exact mechanisms remain unclear. We determined the immune mediator profile in the vitreous of eyes with vitreoretinal B-cell lymphoma. METHODS We studied 28 eyes (23 patients) with vitreoretinal B-cell lymphoma, and 27 eyes (27 patients) undergoing vitre...
PURPOSE Recent studies on temperature control in biology and medicine have found the temperature as a new instrument in healthcare. In this manuscript, we reviewed the effects of temperature and its potential role in pars plana vitrectomy. We also examined the relationship between intraocular pressure, viscosity, and temperature in order to determine the best balance to manipulate the tamponade...
PURPOSE Diabetic retinopathy (DR) is an angiogenic disease that leads to severe visual loss. However, adequate animal models of vitreoretinal neovascularization in proliferative diabetic retinopathy (PDR) have not yet been described. The purpose of this study was to develop a novel ex vivo system for assessing vitreoretinal angiogenic processes that originate from both quiescent and mature vess...
Connective tissue growth factor (CTGF) level is elevated in eyes with proliferative vitreoretinal diseases, such as proliferative diabetic retinopathy and proliferative vitreoretinopathy (PVR), as we previously reported, but its functional characteristics on vitreoretinal cells are yet to be clarified. In this study, we demonstrated a growth-promoting effect of CTGF on cultured hyalocytes and b...
INTRODUCTION To evaluate the vitreoretinal complications in myopes after Visian implantable collamer lenses (ICL) implantation. MATERIALS AND METHODS This is a retrospective, observational, non-comparative clinical study that evaluated 617 consecutive myopes who underwent ICL implantation at the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen between July 2006 and May ...
PURPOSE The purpose of this study was to evaluate the risk of hemorrhagic complications associated with vitreoretinal surgery in patients in whom warfarin therapy was continued throughout the surgical period. METHODS A review of 1,737 consecutive charts of patients undergoing pars plana vitrectomy was conducted. Inclusion criteria included patients on warfarin therapy whose international norm...
