purpose : to assess and to compare stromal and endothelial changes at the cellular level in patients who had photorefractive keratectomy (prk) and laser in situ keratomileusis (lasik) using in vivo confocal microscopy methods : in this semiexperimental study, 32 eyes of 16 patients (4 males and 12 females) with low to moderate myopia [-1.00 to -4.50 diopters (d)] or low to moderate myopic astig...

purpose: to evaluate corneal endothelial cells of donors who died from aluminum phosphide intoxication. methods: endothelial cell count and quality of eight corneas from four donors with aluminum phosphide intoxication were evaluated by slit lamp biomicroscopy and specular microscopy at the eye bank of i.r. iran. confocal scan examination was carried out only in one of the recipients. results: ...

to evaluate corneal endothelial cell changes after intravitreal and subconjunctival injection of avastin (bevacizumab) based on specular microscopic findings.  this prospective interventional study was performed on 82 eyes of 82 patients. forty-two cases with ptrygia received a subconjunctival injection of bevacizumab (2.5mg/0.2ml) and 40 diabetic subjects with retinal neovascularization or mac...

purpose: to compare clinical and confocal scan outcomes after descemet stripping automated endothelial keratoplasty (dsaek) performed for fuchs’ endothelial dystrophy versus pseudophakic bullous keratopathy. methods: in this retrospective comparative study, 47 consecutive eyes of 39 patients with the diagnosis of fuchs’ endothelial dystrophy (n=29, group 1) or pseudophakic bullous keratopathy (...

human bone marrow derived mesenchymal stem cells (hbmscs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. in this study, the differentiation of hbmscs into endothelial like-cells was induced in presence of vascular endothelial growth factor (vegf) and insulin-like growth factor (igf-1). the differentiated endothelial cells were exam...

purpose: to assess the efficacy and safety of laser in situ keratomileusis (lasik) for correction of residual myopia and astigmatism after penetrating keratoplasty (pk). methods: in this prospective interventional case series, lasik was performed on 14 eyes of 13 patients unable to wear glasses or contact lenses after pk. the interval between lasik and pk was at least one year. all patients had...

purpose: to investigate central corneal thickness (cct), endothelial cell characteristics and intraocular pressure (iop) in congenital cataract extracted eyes and to compare the results with eyes of normal age and sex matched controls. methods: cct and iop measurements and specular microscopy were performed in 31 eyes of 17 cases of extracted congenital cataracts and 40 eyes of 20 age and sex m...

mastitis is one of the most serious and costly diseases affecting dairy cattle production. in the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (scc) and subclinical mastitis was investigated in 121 holstein dairy cattle. two alleles of a and b and two genotypes of aa and ab were found in an ecori recognized single nucleotide polymorphism in int...

a simple inexpensive con!nuous quality control method, by means of eight basic blood coun!ng parameters, obtained from automated hematology analyzers, using pa!ent samples, is described. a few samples with low, normal and high values were selected and introduced to the instrument early in the morning as the first count, the results of which are plo#ed on the appropriate chart as dots. the same ...
