We have conducted the first study of sleep in the platypus Ornithorhynchus anatinus. Periods of quiet sleep, characterized by raised arousal thresholds, elevated electroencephalogram amplitude and motor and autonomic quiescence, occupied 6-8 h/day. The platypus also had rapid eye movement sleep as defined by atonia with rapid eye movements, twitching and the electrocardiogram pattern of rapid e...

Introduction Removal of eye is indicated in animals in such cases when it has reached a point where it has no chance of being capable of return of sight and it is very painful to the patient (Mitchell, 2008). Trauma to the eye such as an infected scratch injury or puncture to the eye by fighting with other animal or hitting of the eye with sharp object), tumors of the eye, glaucoma (increased p...

results males (8,593 patients) were more likely to have eye trauma than females (1,262). the mean age for the outpatient cases was 20.3 ± 16.39 years and for the inpatient cases it was 22.7 ± 18.95 years. the workplace was the most common site for trauma and the cornea was the most reported anatomically injured site. for those patients who had not used safety and protection equipment, 93.1% wer...

purpose: dry eye syndrome is a multifactorial disorder of the tear film and ocular surface that results in eye discomfort, visual disturbance, and often ocular surface damage. studies suggest that the prevalence of clinically diagnosed dry eye syndrome (des) is 0.4%. to 0.5%, which is highest among women and the elderly. the burden of des can be substantial, affecting visual function, daily act...

Monkey is highly adaptable live in varying landscape settings to different habitats include the tropical rainforests and also inhabit villages towns cities Southeast Asia. Eye Trauma caused by Bites rare often a zoo, public park for tourists. This case one of cases that we met emergency eye injury at provincial hospital Mekong Delta, Vietnam. A woman when approaching common squirrel monkey bit ...

accidental infection with animal filarial worms in humans is a dilemma for clinicians and parasitolo­gists throughout the world. to date a variety of such rare parasitoses have been reported mostly in tropics and subtropics. human dirofilariasis is among those unusual zoonotic infections that occasionally have been observed in the eye and in subcutaneous areas exhibiting with nodule for­mation....

BACKGROUND Dry eye is a common disease worldwide, and animal models are critical for the study of it. At present, there is no research about the stability of the extant animal models, which may have negative implications for previous dry eye studies. In this study, we observed the stability of a rabbit dry eye model induced by the topical benzalkonium chloride (BAC) and determined the valid tim...

PURPOSE Previous studies have shown that binocular coordination during saccadic eye movement is affected in humans with large strabismus. The purpose of this study was to examine the conjugacy of saccadic eye movements in monkeys with sensory strabismus. METHODS The authors recorded binocular eye movements in four strabismic monkeys and one unaffected monkey. Strabismus was induced by first o...
