When two different stimuli are presented continuously to each eye, the percept alternates over time between the left-eye stimulus and right-eye stimulus. The perceptual alternation can be slowed or even stopped, however, if the same stimuli are presented intermittently (D. A. Leopold, M. Wilke, A. Maier, & N. K. Logothetis, 2002; J. Orbach, D. Ehrlich, & H. A. Heath, 1963). A basic question is ...

AIM To assess the short-term efficacy of hypotonic 0.18% sodium hyaluronate in patients with evaporative tear-sufficient dry eye due to lipid tear deficiency (LTD). METHODS This was a randomised, double-blind, controlled, exploratory study. A total of 10 patients with dry eye due to LTD were treated as follows: one drop of hypotonic 0.18% sodium hyaluronate in one eye and one drop of isotonic...

Introduction: Nowadays, excessive computer use in the workplace has raised concerns about the health status of VDT workers, particularly complaints about eye discomforts. Due to the importance of the eyelids and eye closure parameters on eye health during computer works and the direct effect of monitor height on these parameters, this study was aimed to examine the effect of different monitor h...

Interindividual variation has been shown in the rates at which subjects alternate in perception during viewing of binocular rivalry and other ambiguous figures. A similar pattern of interindividual variation is evident in the rate of eye movements. The aim of this study was to determine whether individual differences in the rate of binocular rivalry predict individual differences in the rate of...

c o i f i n S t e p Eye Safety is Everyone’s Business” is the theme designated by the National Eye Institute (NEI) for the observance of this year’s Healthy Eyes Month (see igure 1). Each day, about 2,000 U.S. workers sustain ob-related eye injuries that require medical treatment, acording to the U.S. Centers for Disease Control and Preention’s (CDC) National Institute for Occupational Safety n...

majority of practical terms in ophthalmology were compiled firstly in muslims` medical dictionary. anatomical and pathological terms such as retina and cataract were improved in this lexicon. mohammad ghazi, in journal of azziae, has considered ophthalmology as an innovation which was firstly introduced by muslim arabs. their attempts promoted this science and retained it the best for a long ti...

Smooth pursuit and vestibularly induced eye movements interact to maintain the accuracy of eye movements in space (i.e., gaze). To understand the role played by the frontal eye fields in pursuit-vestibular interactions, we examined activity of 110 neurons in the periarcuate areas of head-stabilized Japanese monkeys during pursuit eye movements and passive whole-body rotation. The majority (92%)...

Background: Long-term ultraviolet (UV) A eye irradiation in mice initiates the induction of photoaging. However, the changes in the eye due to long-term exposure to UVA radiation are still unclear. Methods: Male C57BL/6j (control) and inducible nitric oxide synthase knockout (iNOS –/– ) mice were used in this study. The eyes of the mice were locally exposed to UVA radiation for 12 months. Resul...

Abstract Current eye-typing systems are suffering from the needed dwell timeout which limits the possible entry rate. In this position paper we discuss how the usage of eye-traces on on-screen keyboards could be used for almost dwell timeout free gaze based communication. ...
