Retrobulbar hemorrhage and permanent visual loss are rare presentations following traumatic asphyxia. In this case, bilateral permanent visual disturbance developed in a woman after chest-crushing trauma without direct trauma to the orbits. A computed tomography scan confirmed bilateral retrobulbar hemorrhages. An ophthalmologic exam revealed bilateral subconjunctival hemorrhages and severe lid...

sleep plays a vital role in regulating physiological mechanisms in the human body. nowadays, by the change of lifestyle and as a consequence of longer work hours and increased accessibility to media, sleep disturbance becomes a common problem in modern society. many studies demonstrated that sleep disturbance triggers a systemic low-grade inflammation by increasing the level of several cytokine...

One of the first large research projects on human control behavior performed at Delft University of Technology is the work of Hosman and Van der Vaart. In their tracking experiment, Hosman and Van der Vaart investigated the influence of visual and vestibular motion cues on human control behavior in a situation similar to manual control of an aircraft. In these compensatory tracking tasks, subje...

In the previous letter, we reported a case of recurrent sniffing of toluene and methanol, and discussed the relationship between neuro-psychological symptoms and urinary findings1). As the patient has neither complained of visual disturbance nor been diagnosed with optic nerve alteration, which is well-known sequela of methanol poisoning, we were interested in the urinary excretion of methanol ...

Dry eye disease (DED) is a highly prevalent chronic ocular disorder that can lead to significant discomfort and visual disturbance. It is a potentially debilitating condition that can have significant negative impact on quality of life. A diverse range of management options exists for DED, including tear supplement products, anti-inflammatory agents, immunomodulators, punctal occlusive devices,...

We aimed to compare the therapeutic effect of Avonex (Av), Betaferon (Be) & Rebif (Re) on the Expanded Disability Status Scale (EDSS) in Multiple Sclerosis (MS). Ninety patients referring to Farshchian Hospital were entered in this study. The patients were divided into three equal groups: group 1 received Av, group 2 received Re and group 3 received Be, and after 24 months, comparison was done ...

The symposium on M. pneumoniae respiratory disease has examined the clinical expression of infection in adults and children, the pathophysiologic disturbances which occur, and the laboratory diagnosis by isolation and serology. That these infections are very common has been well documented; however, a variable incidence over periods of several years tends to minimize importance of the disease f...

S disturbances in preschool children tend to persist, as the child grow older and the mothers perceived their child's sleep problems as stressful to them and their family life. In 84% of SD infants these problems persisted after 3 years of age (1) and were still present in 75% of 8 years-old children having presented SD at 3 years (2). Pollock (3) reported a significant increased risk of sleep ...

BACKGROUND Visual disturbance, visuo-spatial difficulties, and exacerbations of pain associated with these, have been reported by some patients with Complex Regional Pain Syndrome (CRPS). AIMS We investigated the hypothesis that some visual stimuli (i.e. those which produce ambiguous perceptions) can induce pain and other somatic sensations in people with CRPS. METHODS Thirty patients with ...

PURPOSE To investigate the mechanism of voriconazole-induced transient visual disturbance in humans. METHODS andard full-field electroretinograms (ERGs) were recorded from monkeys treated intravenously with voriconazole. In addition, photopic ERGs elicited by long-duration stimuli (ON-OFF response) were also recorded from monkeys receiving intravenous voriconazole or intravitreal 2-amino-4-ph...
