background and objective: the frequency and pattern of eye neoplasms differ in various geographic areas. our aim was to determine the distribution of patient age, gender, ocular tumor origin, location and histological type in our region. materials and methods: in this cross-sectional study, all of the 384 eye globe enucleation cases carried out during a 10-year period in farabi medical center i...

Fatigue affects operators’ safe operation in a nuclear power plant’s (NPP) main control room (MCR). An accurate and rapid detection of fatigue status is significant to operation. The purpose the study explore way detect operator using trends eyes’ blink rate, number frames closed specified time (PERCLOS) mouse velocity changes operators. In experimental tasks simulating operations, clustering m...

coordination, body and limb designs are related to the environmental objects and events. the aim of this study was to investigate the necessity to implement rope jumping program in iran schools and since one of the major problems in learning how to write is eye–hand coordination, the effect of a rope jumping training course on eye–hand coordination was investigated in the fourth grade elementar...

purpose : fluoroquinolones are widely used antibiotic for prophylaxis of intra and postoperative infections in individuals undergoing cataract surgery. this study was designed to assess the penetration of ciprofloxacin into the ocular aqueous humor (topical only versus topical and oral administration). methods : studied population (n=47) consisted of two groups: group one (n=26) and group two (...

During Drosophila eye development, cell proliferation is coordinated with differentiation. Immediately posterior to the morphogenetic furrow, cells enter a synchronous round of S phase called second mitotic wave. We have examined the role of RBF, the Drosophila RB family homolog, in cell cycle progression in the second mitotic wave. RBF-280, a mutant form of RBF that has four putative cdk phosp...

purpose: to report the development of cataract after corneal damage by dungle beetle prongs. case report: a 28 year-old man, resident of the village chah setareh, sabzevar, presented complaining of trauma to the right eye with the dangle beetle while motorcycling. slit lamp examination revealed six corneal perforations, hyphema (50% of anterior chamber) percent, iris sphincter rupture, and rupt...

PURPOSE To evaluate normal blood flow velocity and Doppler indices of the ophthalmic arteries from birth to hospital discharge of inborn infants at birth weights between 500 and 1500 g and gestational age <or=32 weeks. METHODS A longitudinal prospective study with Doppler ultrasound was conducted in both eyes at 24 hours, 7 and 28 days, and hospital discharge for systolic and diastolic veloci...

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...

Introduction: The decline of visual function with increasing age is a significant concern in elderly. Despite previous work on prevalence of specific ophthalmic pathologies, there has not been enough valid data about overall eye disorders in Tehran yet, and it is poorly defined and not underpinned by strong evidence. The purpose of this study was to investigate the common eye disorders in the e...

Infrared thermometry was employed by Alio and Padron (1) to study the temperature of the anterior segment of the eye in normal individuals between 15 and 80 years of age, who noted a decrease with advancing age. Efron et al (2) used a wide field color coded infrared imaging device and noted that following a blink, the geometric center of cornea showed cooling at a rate of 0.03±0.02 °C per secon...
