purpose : to evaluate the correlation of central corneal thickness (cct) with refractive error and keratometry in a group of patients eligible for laser keratorefractive surgery, which may serve as a bias in studies on intraocular pressure (iop) measurement methods : in a cross sectional observational study, the right eyes of 340 patients who underwent laser keratorefractive surgery during the ...

results the mean udva (logmar) improved significantly from 1.13 ± 0.21 preoperatively to 0.24 ± 0.13 postoperatively (p < 0.001), and the mean cdva (logmar) improved significantly from 0.39 ± 0.12 to 0.19 ± 0.09 (p < 0.001). the mean cylinder of manifest refraction decreased significantly by 4.00 diopter (d) (p < 0.001). the mean spherical equivalent error (se) decreased significantly from −6.0...

purpose : to investigate the correlation between corneal biomechanical properties and tomographic parameters of pentacam methods : corneal biomechanical properties and tomographic results of 36 normal subjects were measured by ocular response analyzer (ora) and pentacam and the correlation between these two measurements were analyzed with pearson correlation test with spss version16. results : ...

Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene. Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation. Methods: In 276 graft recipients who mainly underwen...

in the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. acute corneal pain was induced by the local application of hypertonic saline (5 m nacl) on the corneal surface, and the number of eye wipes was then counted for 30 s. subcutaneous (s...

A 67-year-old male with a history of alcohol dependence and opioid addiction was admitted to the inpatient medicine unit from the emergency department with a diagnosis of failure to thrive. He was hemodynamically stable with an oxygen saturation of 98% on 2 litres of oxygen by nasal cannula. The patient appeared thin, dishevelled and intoxicated, but was alert and conversant. He had numerous sc...

purpose: to determine the indications for and surgical techniques of corneal transplantation at labbafinejad medical center (lmc) from 2004 to 2007. methods: in this descriptive study, records of 756 patients who had undergone corneal transplantation from october 2004 to october 2007 were reviewed. results: overall, 504 male (64.9%) and 272 female (35.1%) subjects with mean age of 41.29±21.25 (...
