background and aims: cytomegalovirus (cmv) infection is very common in the population. virus belongs to the family herpesviridae, whose representatives are characterized by the ability to cause the human body's latent persistent infections. the goal of the study is to assess the cmvv infection frequency and pcr method in the choice of cmv in inflammatory eye disease, comparing with cmv pre...

purpose: to report a case of recurrent keratoconus after penetrating keratoplasty (pk). patient and findings: a 31-year-old male patient who had undergone pk in his right eye for keratoconus 10 years ago presented with gradually decreased vision in the right eye. clinical, topographic, and histopathologic features of the cornea including irregular myopic astigmatism, central and paracentral cor...

purpose : granular cell tumors (gct) are benign unusual neoplasms which have been proven to have a schwann cell phenotype. they rarely occur in the eye region. case reports : we report three cases of gct in the ocular adnexa including palpebra, subconjuctiva and orbit which rarely occur. patients are, a young girl with the lesion in orbit and presentation of proptosis, a middle aged man with th...

Introduction: In this paper, by complete definition of human eye containing the various parts and their materials, the difference between this model and a homogeneous water phantom are compared for two ophthalmic plaques using 125I and 103Pd. Material and methods: The simulation of the two phantoms were performed in the MCNP-4C code and by using the geometry of a three-dimensional eye, differen...

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...

Eye fixations are periods of relative stability derived from continuous eye position (or eye movement) data. In order to define eye fixations, researchers often assume that the eye(s) will not move beyond a particular spatiotemporal window (i.e., a spatial area towards which the eye is directed within a particular period of time). However, exact specifications of this window vary from field to ...

A 65–yrs-old man referred for an ocular discomfort and red eye. The clinical diagnosis was leech in the left eye and its species confirmed as being Limnatis nilotica. Ocular leech infestation should be considered in patients with a history of swimming or washing their face in streams and lakes. Attention should also be given to ocular leech infestation in the differential diagnosis of ocular tr...

Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...
