Temperature has been used to diagnose human’s health since 400 B.C. where Hippocrates reported disease is to be found whichever part of human body is in excess heat or cold. This idea is still widely applied nowadays and the advance in infrared thermography technology is furthering the idea into more sophisticated diagnosis techniques, such as detection of breast cancer. Detection of ocular dis...

A scleral contact lens lies on the sclera, not cornea, which differs from a rigid gas permeable (RGP) lens, and has shown successful clinical outcomes in patients unable to tolerate glasses or RGP lenses because of severely deformed cornea. In addition, forms tear film between cornea that stabilizes ocular surface could be useful therapeutic option. The mini-scleral is option for visual improve...

purpose: to determine bacterial contamination of corneas and corneal storage media provided from the eye bank of i.r. iran to rasool akram medical center. methods: this descriptive study was performed on 70 corneoscleral rims and corneal storage media. one milliliter of corneal storage media and the corneoscleral rim were sent to microbiology laboratory at the time of penetrating keratoplasty a...

Our goal is to prove that during corneal perforation, when it larger than 3 mm, we should not rush perform keratoplasty (cornea transplant). First, do our best and fight the end preserve a patient's own cornea, in which amniotic membrane will help us. In 15 patients with where size of perforation exceeded 3-4 surgical treatment was performed piece applied cornea. 14 out 15, their cornea moderat...

introduction: acanthamoeba is an opportunistic protist, which is ubiquitously distributed in the environment. infection with acanthamoeba spp. poses threat to human health, such as, acanthamoeba keratitis (ak) that is a vision-threatening infection of the cornea. this study aimed to identify the species of acanthamoeba strains isolated from cornea of keratitis patients by polymerase chain react...

background: the ostrich is an interesting subject concerninganimal evolution and morphology studies. it has been speculatedthat ostrich eyes would have distinct tissue structures and this hasnot been previously studied in detail. objectives: the aim of thepresent study was to investigate the histology of the outer layer ofthe ostrich. methods: ten mature ostriches were chosen from anostrich bre...

Tactile palpation is a simple technique that can prove useful for estimating intraocular pressure (IOP) in primary healthcare settings, mainly in the absence of equipment, for very young children, patients who are intellectually challenged, those with eyes with extremely irregular corneas, and patients with corneal prostheses. Accordingly, this technique can also aid in the diagnosis of high IO...

Introduction: The present study aimed to present a numerical analysis of the penetration depth,  specific absorption rate (SAR), and temperature rise in various eye tissues with varying distance between radiation source and exposed human eye tissues (i.e., cornea, posterior chamber, anterior chamber, lens, sclera, vitreous humor, and iris) at frequencies of 900 and1800 MHz. Materials and Method...
