EXPERIMENTAL EVALUATION OF A IOTA-CARRAGEENANIPOLYVINYLPYRROLIDON GEL AS VITREOUS SUBSTITUTE KOBUCH K. SCHLODERER M. LE-RUPPERT K. UEDA N. GABEL V.P. Deportment of Ophthalmology , Uniwrsttv clinic Regenrburg (G) Pm: A new hydrogel composed ofiota-carrageenan/polyvinylpyrrolidon (icgn/pvp) was tested in rabbit eyes to dctennine its intraocular tolerance and to evaluate its suitability as a vitre...

BACKGROUND Stimulus deprivation amblyopia is the principal cause of visual impairment in infants with unilateral congenital cataract. Even if lensectomy is undertaken at an early age, intensive postoperative occlusion of the phakic eye is essential for the development of useful vision in the aphakic eye. Despite this, the optimum method of regulating occlusion therapy is uncertain. METHODS In...

PURPOSE The purpose of this study was to determine whether nystagmus has a role in silicone oil emulsification after pars plana vitrectomy and silicone oil injection for complex retinal detachment. METHODS A retrospective review was conducted of the clinical and operative records of eight eyes with nystagmus that underwent pars plana vitrectomy and silicone oil injection for repair of retinal...

PURPOSE The authors used a monkey model to evaluate intraocular lenses (IOLs) for the treatment of infantile cataract in humans. Specifically, they sought to assess the effectiveness of IOLs, with and without occlusion therapy, in preventing amblyopia. METHODS A diffuser contact lens was placed on one eye each of 11 neonatal monkeys to simulate an infantile cataract. A unilateral lensectomy, ...

PURPOSE To describe the results of lens-sparing vitrectomy for the correction of retinal detachment associated with retinopathy of prematurity (ROP) and its associated complications. METHODS Seventeen patients who underwent a lens-sparing vitrectomy for stage 4 and stage 5 ROP with plus disease at Seoul National University Children' s Hospital between 1999 and 2003 were enrolled in this study...

AIM To investigate the prevalence and the outcome of management of fibrovascular ingrowth (FVI) in eyes undergoing vitreous cavity washout (VCWO) following vitrectomy for diabetic retinopathy. METHOD FVI was searched for at VCWO for in 19 consecutive eyes with proliferative diabetic retinopathy undergoing vitreous surgery for recurrent vitreous cavity haemorrhage over an 18 month period; the ...

PURPOSE To describe the incidence of unilateral congenital cataract associated with minimal (ultrasonically undetectable) levels of persistent fetal vasculature in the first 18 months of the life and to report surgical methods for intraocular lens implantation, using 25-gauge vitrectomy system. METHODS Retrospective review was made on 16 consecutive patients with bilateral or unilateral conge...

purpose: to determine the incidence and risk factors associated with glaucoma following congenital cataract surgery (ccs) in children under age of 15 methods: this prospective cohort (since 2006) consisted of children less than 15 years of age who underwent cataract surgery with or without intraocular lens (iol) implantation. the role of the following factors on the development of glaucoma afte...

purpose : our purpose is to determine the structural outcome of 25-gauge vitrectomy in addition to scleral buckling in stage 5 retinopathy of prematurity (rop). methods : in a prospective interventional case series, 21 eyes with stage 5 rop underwent 25-gauge vitrectomy and scleral buckling. demographic data, disease activity (having plus disease or neovascularization) and the procedure manner ...
