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 and Objective: Proper method and machine for corneal evaluation is an important factor in many anterior segment interventions. This study was performed to compare the mean keratometry (K) readings obtained with an IOL Master and Pentacam for intraocular lens power calculation in normal subjects with no history of refractive surgery. Materials and Methods: Mean K values were obtained ...
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...
ABSTRACT Mycotic Keratitis, an important ophthalmologic problem, especially among the outdoor workers in the tropic regions, is frequently caused by filamentous fungi. Following trauma, a corneal ulcer developed in 3 male patients residing in rural areas of Sari. Traumatizing agents were likely paddy rice, soil and dust. Direct examination of all the corneal scrapings showed septate branched ...
BACKGROUND We report a rare case of syphilitic intraocular inflammation with occlusive retinal vasculitis treated with intravitreal injection of bevacizumab (IVB) in addition to conventional therapy for syphilis. CASE A 24-year-old woman who complained floaters in both her eyes showed occlusive retinal vasculitis OU. According to the high titer of the Treponema antigen and characteristic cuta...
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...
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 (...
purpose: to evaluate corneal thickness changes after soft contact lens (scl) removal in lasik candidates. methods: fifty lasik candidates (100 eyes) with history of daily wear scl for at least 6 months were enrolled in this descriptive study. central corneal thickness was measured by ultrasonic pachymetry immediately after lens removal and then repeated daily at the same time, until the thickne...
Abstract Background: Although corneal graft may be rejected by the immune system of the recipient it remains as the most successful operation as compared to transplantation of other tissues. Since most patient do not reject the grafts, those who do are in the minority. This study was carried out to assess the usefulness of the cure frailty model for determining the significance of risk facto...
purpose: to specify histopathologic features of corneal involvement in a case with xeroderma pigmentosum (xp). case report: a 19-year-old man with a clinical diagnosis of xp presented with bilateral corneal leukoma and decreased visual acuity predominatly in his right eye. penetrating keratoplasty was performed in the right eye due to severe corneal opacity, vascularization and lipid deposition...
