View clinical trials related to Dry Eye Syndrome.
Filter by:Dry eye syndrome (DES) is a highly prevalent ocular condition with severe consequences for the patients reaching from ocular discomfort in its simplest form up to visual impairment and corneal ulceration in severe cases. Data from epidemiological studies indicate that DES is a common disease, especially in the elderly population, affecting up to 20% of adults aged 45 years or older. Topical lubricants are a mainstay of therapy, but data on its effect on tear film thickness and the corneal residence time are lacking. Recently, a new objective method for assessment of tear film thickness by optical coherence tomography has been developed. The present study aims to investigate the corneal residence time of an established topical lubricant compared to placebo in patients with DES and healthy controls.
The "dry eye syndrome" DES is a highly prevalent ocular disease, in particular in the elderly population. One mainstay of therapy for patients suffering from DES is the use of topically administered lubricants. However, despite many efforts, no "ideal" formulation has yet been found. Recently, Croma Pharma has introduced chitosan-N-acetylcysteine eye drops, designed for treatment of symptoms related to DES. Chemically, chitosan is a polycationic biopolymer with favourable biological properties such as high biocompatibility and low toxicity. Additionally, the new formulation comprises N-acetylcysteine, which has been used in ophthalmology because of its mucolytic properties for several years. Based on theoretical considerations, one can hypothesize that the new chitosan derivative may show an increased adhesion to mucins of the ocular surface and may therefore be particularly beneficial in reducing the symptoms associated with DES. We have recently shown in a phase I trial that single instillation of chitosan-N-acetylcysteine eye drops is well tolerated in young healthy subjects. However, no data is yet available about safety and tolerability of chitosan-N-acetylcysteine in subjects wearing contact lenses. This is of special interest because the tear film is critical to successful contact lens wear. Disturbances of the quantity or quality of the tear film results in intolerance of contact lens wear and possible damage to the ocular surface. This trial seeks to investigate the local tolerability and possible ocular discomfort of chitosan-N-acetylcysteine eye drops after repeated instillation .
This is a Phase 1b, multi-center, double-masked, randomized, placebo-controlled, parallel-group study designed to evaluate the safety and biological activity of two doses of EBI-005 ophthalmic solution versus placebo in subjects with moderate to severe Dry Eye Syndrome. Approximately 72 subjects will be enrolled and randomized in this study at up to 9 centers located in the United States (US). Subjects will be enrolled in two groups or cohorts. The first enrollment group will consist of 33 subjects.
Dry Eye Syndrome (DES) is a common condition that affects approximately 20% of adults aged 45 and older. Although several clinical tests for the diagnosis and monitoring of DES are available, currently no gold standard for the assessment of DES exists. It has, however, been hypothesized that the assessment of tear film osmolarity may be a new and promising approach of an objective and non-invasive method for diagnosis and monitoring of treatment success. Recently, a new commercially available instrument (TearLab®, OcuSens Inc, San Diego, USA) for the assessment of tear film osmolarity has been introduced. This instrument allows for the easy and non-invasive determination of tear film osmolarity. Unfortunately, no data about reproducibility are yet available. Consequently, the current study sets out to investigate the short time reproducibility of tear film osmolarity measurements using the TearLab® instrument.
The purpose of this study was to assess the efficacy of the SYSTANE® family of products (SYSTANE® Lid Wipes, SYSTANE® BALANCE Lubricant Eye Drops, and SYSTANE® Vitamins) on meibomian gland functionality in subjects with lipid deficiency related to evaporative dry eye as compared to the standard of care warm compresses.
The purpose of this study is to evaluate the ability of SYSTANE® BALANCE and SYSTANE® Gel to improve comfort in subjects with dry eyes.
The purpose of this study is to evaluate the repeated use of SYSTANE® BALANCE on stabilizing the tear film of dry eye patients with an unstable tear film.
The primary purpose of this study is to assess the efficacy, tolerability and safety of RX-10045 Ophthalmic Solution in patients with Dry Eye Disease.
This study is to determine the efficacy and safety of 3% or 5% DA-6034 eye drops compared with placebo in dry eye syndrome.
The purpose of this study is to evaluate the efficacy and safety of rebamipide ophthalmic suspension in subjects with dry eye syndrome.
