Purnose The incorporation of polymers into artificial tears both increases the thickness of the precorneal tear film and decreases the rate of drainaae of the for8nulations. On the basis of these effects, we hypothesized that a time study of the artificial increase in tear volume induced by such formulations could be a useful method of assessing their precorneal residence time. Methods New Zeal...

BACKGROUND Vitamin D deficiency is associated with a range of systemic diseases including ocular disorders. The objective of this study is to measure tear vitamin D levels and investigate the correlation between serum and tear vitamin D levels. METHODS A total of 48 healthy volunteers without any systemic and ocular disease were recruited for this observational cohort study. Serum was collect...

OBJECTIVES To assess the effects on dry eye symptoms and tear dynamics of switching from a prostaglandin with a preservative to a preservative-free prostaglandin. MATERIAL AND METHODS Fourteen patients (N=28 eyes) with open-angle glaucoma and dry eye symptons, treated with preserved latanoprost, travoprost or bimatoprost were included in this uncontrolled prospective study. Ocular symptoms we...

Dry eye syndrome (DES, Keratoconjunctivitis sicca) is a common disorder of the tear film caused by decreased tear production or increased evaporation. Changes in tear composition also promote inflammation on the ocular surface by various mechanisms. Artificial tear drops, tear retention treatment, stimulation of tear secretion, or anti-inflammatory drugs may be used for dry eye treatment accord...

BACKGROUND Tear gas shells are used to disperse the mob during any type of street protests. Vascular injuries due to tear gas shells have not been reported. The present study was undertaken to analyse the pattern, presentation, management and outcome of vascular injury due to tear gas shells. METHODS Eighteen patients with vascular injury caused by tear gas shells from 1(st) Jan. 2008 to 31(s...

PURPOSE To determine which US signs are important in the diagnosis of a surgically identifiable supraspinatus tendon tear. MATERIALS AND METHODS Fifty consecutive ultrasonographic (US) studies of the shoulder in patients who underwent arthroscopic follow-up were retrospectively reviewed by a musculoskeletal radiologist. US images of the supraspinatus tendon were evaluated for tendon nonvisual...

PURPOSE To study tear trypsin inhibitory capacity (T-TIC), serum trypsin inhibitory capacity (S-TIC) and their relationship to matrix metalloproteinases (MMP)-1 and -9 in patients with vernal keratoconjunctivitis (VKC). METHODS In the first phase of the study, inactivation of alpha-1 antitrypsin (AAT) by MMP-1 and -9 was investigated in vitro. Subsequently, tear samples were collected after c...

OBJECTIVE To determine whether patients with acute posterior vitreous detachment with pigmented vitreous granules or hemorrhage have a higher likelihood of retinal tear compared with those with qualitatively normal vitreous examination findings. METHODS A multicenter cross-sectional study was performed in 3 peripheral ophthalmic clinics. Patients with acute posterior vitreous detachment were ...
