background rheumatoid arthritis (ra) is a chronic inflammatory disease with extra- articular involvement. eyes in particular are one of the most common sites of involvement in rheumatoid arthritis. on the other hand, dry eye syndrome is the most common conflict in terms of management. particular studies suggested dry eye has been associated with greater rheumatoid arthritis severity, but its as...

ocular dryness is a well-recognized adverse side effect of many topical and systemic medications. in psychiatry, patients who have consumed such drugs as lithium carbonate and sodium valproate frequently experience dry eye symptoms. the purpose of this study was to compare tear film stability between patients who use these drugs with those patients who are not on medication.after obtaining info...

Dry eye syndromes can involve both nociceptive and neuropathic symptoms. Nociceptive symptoms are the normal physiological responses to noxious stimuli. Neuropathic symptoms are caused by a lesion or disease of the somatosensory nervous system and can be the result of hypersensitisation of peripheral or central corneal and conjunctival somatosensory nerves. For example, inflammation could induc...

OBJECTIVE To characterize chemokine receptor CCR5 expression on the conjunctival epithelium in dry eye syndromes. METHODS Conjunctival impression cytology samples were obtained from normal subjects (n = 15) and patients with dry eye syndrome (n = 45). Cells were harvested from impression cytology samples, and flow cytometry was performed to quantitatively analyze the cell surface expression o...

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...

Sex steroid deficiency has been linked to the development and/or progression of a wide variety of clinical disorders, including cardiovascular disease, osteoporosis, obesity, insulin resistance and certain cancers. We hypothesize that sex steroid deficiency specifically that of androgens, may also be a critical pathogenetic factor in the etiology of dry eye syndromes. Dry eye syndromes are a le...
