Active clinical trials for "Dry Eye Syndromes"

The objective of this study is to evaluate the safety and effectiveness of OC-02 nasal spray compared to placebo on signs and symptoms of dry eye disease (DED).

Traditionally, Manuka honey has been used to combat against bacteria and reduce inflammation (the body's way of reacting to infection, irritation or other injury). Due to the inflammatory nature of dry eye, Manuka eye drops show promise as a treatment for dry eye disease. The aim of this research is to compare the effects of two over the counter eye drops that are used to treat dry eye conditions over a one month period.

The present study aimed to evaluate and compare the efficacy of a 1 month clinical trial of 50% AS for the treatment of severe dry eye syndrom (DES) based on Schirmer's Test, tear break-up time (TBUT), fluorescein staining, and ocular surface disease index (OSDI) scores, as compared to conventional preservative-free artificial tears (PFAT) plus 0.05% COE treatment in patients with severe DES

Upper eyelid treatment has not been used with previously described methods of treatment of dry eye disease using intense pulsed light therapy because the upper lids disease was typically not as advanced as lower lid and because direct treatment of the upper lid was not felt to be necessary as each light pulse extended over the entire periorbita even when concentrated on the lower lid.

Eyes with abnormal tear film function have been found to show larger optical aberrations than normal eyes which may be attributed to the unstable and irregular tear film, uneven ocular surface, and increased scatter due to the exposure of the rough surface of corneal epithelium after tear break-up. These hypotheses have been supported by the findings that instillation of artificial tears (sodium hyaluronate preparation) in dry eye patients reduces both corneal and ocular aberrations, improving the optical quality of the retinal image. However, the previous studies only evaluated the short-term effects of a single administration of an artificial tear but did not determine the duration of action or inflection point at which the ocular aberrations increase back to baseline. Also, there has clearly been no such clinical trial that has been a well randomized controlled study to date. This report is the first randomized controlled trial that investigated the long-term effects of a single dose of sodium hyaluronate-based artificial tears on wavefront aberrations in patients with dry eye.

BAK is one of the most frequent preservatives in eye drops. BAK is a quaternary ammonium salt with surfactant qualities. It can be bacteriostatic or bactericidal depending on the concentrations used. It has been shown to be effective against most bacteria with a few exceptions, such as Pseudomonas aeruginosa, or picornaviruses. It as been widely used in eyedrops, nose sprays, hand and face washes, mouthwashes, spermicidal creams, and in various other cleaners, sanitizers, and disinfectants. BAK gained popularity when it was first introduced because it also enhances corneal penetration of some drugs by causing epithelial separation. It is present in several ophthalmic formulations, including most of the antiglaucoma medications. If used chronically, BAK has been found to cause ocular surface changes, such as dry eye and punctuate keratitis. BAK has also been suggested to promote a break in the blood aqueous barrier, which may lead to undesirable consequences, such as uveitis and cystoid macular edema. However, this information is controversial. The purpose of this study is to evaluate the consequences of BAK on the blood-retinal and blood-aqueous barriers of pseudophakic patients receiving BAK-preserved lubricating drops.

The purpose of this study was to determine if difluprednate ophthalmic emulsion is effective in reducing the ocular symptoms of dry eye disease, as measured by a global Visual Analog Scale (VAS) discomfort score.

Objective of this study is to evaluate the tolerance and potential benefit of moisture chamber glasses for dry eye in an Asian population. In this clinic based prospective interventional study, we aim to recruit patients (until 10 patients complete the study) who have evaporative dry eye due to exposure to environmental stress (such as frequency of out door activities) and keen to try out moisture chamber glasses/ eyewear from the dry eye clinic in Singapore National Centre. After informed consent, these patients will be prescribed 7eye( Panoptx)™ moisture chamber glasses/eyewear for 3 months and will be monitored on a diary for the amount of time wearing eyewear for 2 weeks and the number of eye drops for each type of medication used. Other outcomes will be changes in symptoms of dry eye using visual analog scale, as well as objective signs of dry eye (eg. corneal fluorescence staining and tear break up time (TBUT). As moisture chamber spectacles are currently not available as a treatment option for dry eye in Singapore, the findings of this study will give an insight to the efficacy of this new treatment modality in our population.

The purpose of this study was to determine if Sodium Hyaluronate, 0.18% is effective in treating the signs and symptoms of dry eye disease.

This study will evaluate ocular surface lubricants in subjects with dry eye syndrome.
