AIn this study a simple and reliable stability-indicating RP-HPLC method was developed and validated for analysis of Dexpanthenol in an artificial tear formulation. The chromatographic separation was performed on a HPLC C18 column (25.0 cm  4.6 mm, 5 m) using a mixture of 0.037 M monobasic potassium phosphate in water (adjusted with 0.1% (v/v) phosphoric acid to a pH of 3.2) and methanol (90:...

OBJECTIVE To determine the tear production in dogs admitted to an intensive care unit (ICU). DESIGN Prospective observational study from November 2010-September 2011. SETTING Private emergency and referral hospital. ANIMALS Thirty healthy control dogs and 30 dogs hospitalized in an ICU for treatment of systemic illness without previously diagnosed ophthalmic disorders and no recent histor...

AIM To evaluate in vivo changes after therapy using autologous serum (AS) eye drops in Sjögren's syndrome (SS)-related dry eyes by confocal microscopy. PATIENTS AND METHODS In this study, 24 patients with SS-related dry eyes [12 in AS eye drop therapy and 12 in artificial tear (AT) therapy] and 24 healthy volunteers were recruited. Ocular Surface Disease Index (OSDI), central corneal thicknes...

The eye has two sets of structures that produce tears. Smaller tear glands help maintain a baseline level of moisture on the surface of the eye. Unfortunately, inflammatory conditions like rheumatoid arthritis, Sjogrens disease as well as aging and menopause lead to decreased tear production. As tear production diminishes, the surface of the eye starts to dry out. Further, inflammation of the o...

Aortic dissection is a dangerous pathological condition where blood intrudes into the layers of the arterial walls, creating an artificial channel (false lumen). In the absence of thrombosis or surgical intervention, blood will enter the false lumen through the proximal tear, and join the true lumen again through a distal tear. Rupture of the weakened outer wall will result in extremely high mo...

BACKGROUND/AIMS Among the causes related to the development or perpetuation and aggravation of dry eye disease, oxidative reactions may have a role in the pathogenesis of this disorder. Antioxidants, such as iodide, have shown a strong effect in preventing the oxidative damage to constituents of the anterior part of the eye. In this clinical trial the effectiveness of iodide iontophoresis and i...
