According to Einstein's equivalence principle, inertial accelerations during translational motion are physically indistinguishable from gravitational accelerations experienced during tilting movements. Nevertheless, despite ambiguous sensory representation of motion in primary otolith afferents, primate oculomotor responses are appropriately compensatory for the correct translational component ...

Normal function of the vestibulo-ocular reflex (VOR) coordinates eye movement with head movement, in order to provide clear vision during motion and maintain balance. VOR is generated within the semicircular canals of the inner ear to elicit compensatory eye movements, which maintain stability of images on the fovea during brief, rapid head motion, otherwise known as gaze stability. Normal VOR ...

Ocular herpes simplex virus type 1 (HSV-1) infection elicits a strong inflammatory response that is associated with production of the beta chemokines CCL3 and CCL5, which share a common receptor, CCR5. To gain insight into the role of these molecules in ocular immune responses, the corneas of wild-type (WT) and CCR5-deficient (CCR5-/-) mice were infected with HSV-1 and inflammatory parameters w...

Cortical/cerebral visual impairment (CVI) is clinically defined as significant visual dysfunction caused by injury to visual pathways and structures occurring during early perinatal development. Depending on the location and extent of damage, children with CVI often present with a myriad of visual deficits including decreased visual acuity and impaired visual field function. Most striking, howe...

The vestibulo-ocular reflex (VOR) allows animals to maintain stable gaze during head rotations by generating compensatory eye rotations. The VOR is typically tested using sinusoidal head rotation, and VOR gain is calculated as the ratio of the amplitude of eye to head rotational velocity. Through habituation, prolonged exposure to lower frequency sinusoidal head rotation in the dark decreases V...

PURPOSE To explore the possible influence of ocular growth, refractive error and age on the crystalline lens in school-age children. METHODS A Taiwan nationwide survey of myopia performed in 2006 was used to determine the prevalence and severity of myopia and the changes in ocular components. A total of 11,656 students were enrolled, including 5,390 boys and 6,266 girls, with ages ranging fro...

behçet’s disease (bd) is a multisystem disorder with potential ability to influence the pregnancy outcome and pregnancy is associated with several physiologic alterations which can lead to potential changes in the course of the disease. we studied 77 pregnancies in 69 women with bd. the disease activity was calculated by two methods for three periods of before, during and after pregnancy to eva...

introduction: patients with bilateral weakness (bw) have many difficulties in gaze stability that interfere with their normal function. the aim of this study was to evaluate ocular motor functions in patients with bw to better understand the problem of gaze instability in these patients.   materials and methods: patients were referred from the otolaryngology department for vestibular assessment...

PURPOSE The selective muscarinic antagonist pirenzepine inhibits experimentally induced myopia in avian and mammalian species, including nonhuman primates and adolescent humans. Transient positive lens defocus has a potent inhibitory effect on negative-lens-induced myopia in avian and mammalian models. The purpose of the present study was to determine the influence of daily treatment with piren...

this research was conducted with the aim of identifying the gender identity of women in the movies of war period. four movies of ‘bashu little stranger’, ‘gilaneh’ and ‘from karkhe to the rhine’ were selected and the kinds of women's identity were identified by using discourse analysis in these movies. in these movies, although women tried to fulfill the expectations of society in the form...
