Active clinical trials for "Keratoconjunctivitis Sicca"

This study will evaluate the safety, efficacy, and acceptability of two artificial tears compared to a currently available artificial tear in subjects with dry eye.

To evaluate the efficacy of Systane Ultra in post menopausal women with dry eye.

The purpose of this phase III, open-label study is to determine the safety and tolerability of cyclosporine in the treatment of dry eye syndrome.

The objective of this study is to assess the safety and efficacy of doxycycline 0.025% (ALTY-0501) ophthalmic solution for the treatment of dry eye using the Controlled Adverse Environment (CAE) Model.

Cordyceps cicadae mycelia was tested for amelioration of dry eye symptoms through dietary supplementation. Its efficacy in relief of human dry eye status was assessed by randomized, double-blinded tests, including multiple assessments. The results were compared between the placebo group and the experimental group.

In the elderly population, dry eye syndrome is a highly prevalent ocular disease. One mainstay of therapy for patients suffering from dry eye syndrome is the use of topically administered lubricants. One of the main disadvantages of the formulations currently available for the treatment of DES is the short residency time on the ocular surface, which increases the need for a frequent instillation of the lubricant. Recently, Croma Pharma has introduced chitosan-N-acetylcysteine eye drops, designed for treatment of symptoms related to DES. Based on theoretical considerations and animal experiments, the new chitosan derivative may show an increased adhesion to mucins of the ocular surface and may therefore considerably increase the residence on the ocular surface. This, in turn, would limit the need for frequent treatment and decrease the burden for the patients. It has been shown in recent Phase I studies that chitosan-N-acetylcysteine eye drops are safe and well tolerated after single and repeated instillation. The current study seeks to investigate the ocular residency time after a single dose and after 5 day b.i.d. treatment. For this purpose 2 cohorts are planned: In Cohort I, chitosan-N-acetylcysteine eye drops will be instilled once in one randomly chosen eye, whereas the fellow eye will receive placebo. Measurements of tear film thickness will be performed with optical coherence tomography (OCT) before instillation and 10 minutes, 1 hour, 2 hours, 4 hours, 8 hours, 10 hours, 12 hours and 24 hours after instillation. In addition, ocular scattering of the tear film will be assessed with an Optical Quality Analysis System (OQAS) at the same timepoints. Determination of break up time (BUT) will be performed before and after instillation of the eye drops. In Cohort II, chitosan-N-acetylcysteine eye drops will be instilled once daily in one eye and b.i.d. in the fellow eye on five consecutive days. Measurements of tear film thickness with OCT and OQAS will be performed every study day before the morning instillation and the day after the last instillation. Additionally, patients will be asked to answer the ocular surface disease index (OSDI©) on day 1 and day 6. BUT will be determined before and after instillation of the eye drops.

Dry eye syndrome is a highly prevalent ocular disease with an increasing incidence in the elderly population. Topically administered lubricants are the basis for treatment of this disease. Relief of symptoms in patients with moderate to severe dry eye disease is usually reached by the use of artificial tears during the day. Nighttime relief is often achieved by substances known to be more adhesive to the ocular surface, such as gels.

The purpose of this study is to evaluate the clinical efficacy and safety of 10-weeks oral consumption of Zanthoxylum schinifolium seed Oil (ZSO) in patients with mild dry eye disease.

Individuals with dry eye tend to present with ocular pain which persists despite the use of topical treatment. This could be secondary to somatosensory impairment attributable to neuropathic pain. The purpose of this study is to evaluate the effect of trigeminal nerve stimulation (TNS) on corneal nerves and chronic ocular pain in patients with dry eye.

This study is to evaluate the safety of a new preservative in a lubricant eye drop used four times a day in healthy adults and subjects diagnosed with dry eye.
