artery blood flow and the retinal oxygen tension, however, remained elevated for 15 min. Discussion. The VER from anesthetized animals has been extensively studied by others, and our recordings are similar to those they have obtained. It is not clear which cortical structures generate the different waves of the VER, but in the eye it appears to be primarily foveal in origin. We have previously ...

introduction: cataract is an opacified lens and senile cataract is a common disorder. it is desirable to reduce intraocular pressure (iop) in order to minimize intra and post operative difficulties and complications. many researches have studied the effects of muscle relaxants on iop. comparison effect of atracurium and pancuronium on iop has been evaluated in one study with a small sample size...

purpose: to report a patient with an intraocular lymphoma with history of treated brain lymphoma. case report: a 45-year-old female was referred with moderate chronic intermediate uveitis of both eyes that was unresponsive to medications. she had history of treated brain lymphoma with chemotherapy and radiotherapy 6 years before presentation. systemic workup, laboratory evaluation, brain and or...

purpose : to evaluate distance and near contrast sensitivity (cs) under photopic and mesopic conditions before and after refractive lens exchange (rle) and implantation of the aspheric acrysof restor (sn6ad3 model) intraocular lens (iol) methods : sixty eyes of 30 consecutive patients after rle underwent bilateral implantation with the aspheric acrysof restor iol. the patients sample was divide...

purpose: to evaluate the results of combined chemotherapy and periocular carboplatin injection to control advanced intraocular retinoblastoma (rb). methods: in this prospective interventional case-series, we included 8 eyes of 8 patients with advanced intraocular rb (group c or d in international intraocular retinoblastoma classification, iirc). in these patients, periocular carboplatin was inj...

the purpose of this study was to evaluate the effects of a combination of latanoprost and pilocarpine onthe intraocular pressure in experimentally glaucomatous rabbits. ocular hypertension was induced in 11conscious rabbits by the oral administration of tap water (70 ml/kg) via an orogastric tube. the study wasconducted in three therapeutic groups to test the effects of latanoprost (group l), p...

conclusions: these data demonstrated that the attachment of bacteria to hydrophilic acrylic iols was more than hydrophobic pmma ones independent of the brand. according to these results the bacterial strain might have more hydrophilic properties. augmenting the biomass of biofilm by passing of time demonstrated the key role of time in biofilm formation on the iol surfaces. the differences betwe...

The aim of this study was to evaluate the surface roughness of intraocular lenses (IOLs) generated by the manufacturing process and to determine the roughness parameters of 3D surface using atomic force microscopy (AFM). Intraocular lenses commercially available from a single manufacturer: Pharmacia & Upjohn Co. were investigated. Three intraocular lenses, model 911A CeeOn Edge, were analyzed o...

PURPOSE To quantify and compare the in vitro adherence of Staphylococcus epidermidis and Pseudomonas alcaligenes to different intraocular lenses (IOLs). METHODS Fourteen intraocular lenses were used in the experiment. Four of polymethylmethacrylate (PMMA), four of silicone, four of hydrogel and two of acrylic. Eight intraocular lenses were placed in eight test tubes containing 4 ml of Pseudom...
