Filter by:Allergic conjunctivitis (or ocular allergy) and dry eye disease (DED) are two major ocular surface disorders affecting millions of people. A typical clinical symptom of allergic conjunctivitis is itching which is also observed in subjects suffering from DED. Common symptoms of DED also include a foreign body sensation, dryness, irritation, burning sensation and visual disturbance. Patients with allergic conjunctivitis or moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression. Gel-based artificial tear supplements may offer longer retention times and act as a supplement to the mucin layer. Carbomer (also known as Carbopol polymers) is awater-soluble polymeric resin that exhibit excellent viscoelastic and mucoadhesive properties when compared with other polymers. Carbomer is used in liquid or semisolid pharmaceutical, cosmetics, and ophthalmic formulations as rheology modifiers. Aqueous carbomer gels have been used for the treatment of dry eye and allergic conjunctivitis as they provide prolonged ocular residence time of conventional ophthalmic solutions. Furthermore, carbomer has shown compatibility with many active ingredients, good thermal stability, excellent organoleptic characteristics, and good patient acceptance. For these reasons, an interventional, non-comparative, single-center Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Optrex Double Action soothing and lubricating drops" for itchy and watery eyes. The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with the use of "Optrex Double Action soothing and lubricating drops" according to the Instructions for Use (IFU). Each subject, after signing the Informed Consent Form, will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed. At baseline visit, "Optrex Double Action soothing and lubricating drops" will be prescribed to the enrolled subject. The patient will perform 2 on-site visits: V0 and V2/EOS. To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events and concomitant medications intake.
Tear dysfunction, also known as Dry Eye Disease (DED) is frequently encountered in the clinical practice. It is a multifactorial disease of the ocular surface characterized by insufficient tear production, loss of homeostasis of the tear film, increased osmotic stress of the ocular surface, ocular discomfort and visual disturbance. Hyaluronic acid (HA) is a linear heteropolysaccharide (glycosaminoglycan) with unique hygroscopic, rheological, and lubricating properties. HA is naturally found at the human ocular surface where it contributes to the ocular hydration and lubrication thanks to its capability to bind water molecules.Sodium hyaluronate (SH), the salt form of HA, is widely used in artificial tears to counteract dry eye symptoms by facilitating eyelid sliding and reducing its friction on the corneal-conjunctival surface. Conventional HA-based eye drops contain linear HA. However, artificially cross-linked HA (CLHA) has several advantages over linear HA in alleviating dry eye symptoms. The increased viscoelasticity of CLHA results in a greater stability and a better resistance to the enzymatic degradation by hyaluronidase, while preserving all the properties of linear HA. Furthermore, chemical cross-linking of HA extends its permanence on the ocular surface, thus reducing the number of instillations and increasing patients' compliance. For these reasons, an interventional, non-comparative, single-center Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "Cross-Linked Hyaluronic Acid (CLHA)-based eyedrops" used as intended to improve lacrimal abnormalities, even when associated with dry eye symptoms. The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with use of "Cross-Linked Hyaluronic Acid (CLHA)-based eyedrops" according to the Instructions for Use (IFU). Each subject, after signing the Informed Consent Form (ICF), will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed. At baseline visit (V0), one of the "CLHA-based eyedrops" products will be administered to the enrolled subject. The patient will perform 2 on-site visits: V0 and V2/EOS. To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events and concomitant medications intake.
Dry eye disease (DED), also called keratoconjunctivitis sicca, is a common ocular condition characterized by a loss of homeostasis of the tear film and inflammation of the ocular surface. The typical symptoms of DED include irritation, discomfort, blurred or fluctuating vision. Over the counter (OTC) artificial tears are typically the first line of dry eye treatment; they are meant to supplement the tears that cover the eye's surface. OTC products mimic the different layers of the tear film in order to maintain ocular hydration. HA is found in higher concentrations in the vitreous humor of the eye, cartilage, and the synovial fluid. As a component of the tear film, HA increases the viscosity of the tear film and hydrates and lubricates the ocular surface. HA possesses intrinsic water retention properties, viscoelasticity, and favors the healing of corneal and conjunctival epithelium. For these reasons, an interventional, non-comparative, single-center Post Marketing Clinical Follow-up (PMCF) study was planned to evaluate the performance and safety of "HA-based eyedrops" used as intended to relieve dry eye symptoms. The objectives of the PMCF study are confirmation of the performance, collection of additional safety data regarding expected adverse events and detection of potential unexpected adverse events associated with use of "HA-based eyedrops" according to the IFU. "Hyaluronic Acid (HA)-based eyedrops" are medical devices used as intended to improve the discomfort due to dry eye (for intrinsic and/or extrinsic causes), contact lenses wearing and/or eye surgery. Each Subject, after signing the Informed Consent Form, will enter the screening and baseline phase (the 2 visits will coincide) during which baseline procedures will be completed. At baseline visit (V0), one of the "Hyaluronic Acid (HA)-based eyedrops" products can be dispensed to the enrolled Subjects, depending on Investigator clinical evaluation, and severity of the disease. The patient will perform 2 on site visits (V0 and V2/EOS). To monitor the safety, 1 phone contact is planned (V1) to check for potential adverse events (AEs) and concomitant medications intake.
Evaluation of tear fluid production using Schirmers' tests is a well-known and frequently used examination method in ophthalmology. Schirmers' test objectively indicates the tear fluid production over five minutes by insertion of a filter paper strip in the lower conjunctival fornix. Commonly, this method is used to quantify tear fluid production, but not tear fluid composition. The development of novel, very precise analytical methods opens up new possibilities in the use and application of Schirmers' test strips. A recently introduced analytical method is mass spectrometry. This method allows the detection and quantification of proteins, lipids, and metabolites in very low amounts of samples. Whether systemically ingested agents such as omega-3 fatty acids or acetylsalicylic acid can be detected in tear fluid using this method remains unclear. The aim of this study is to investigate the detectability of 2 different agents (acetylsalicylic acid and omega-3 fatty acids) in Schirmers' test strips from healthy subjects after intake for 1 week by use of untargeted mass spectrometry. Participating healthy subjects will receive either acetylsalicylic acid or omega-3 fatty acids.
The purpose of this study is to evaluate the ocular comfort of 3 ocular lubricants and a comparator.
Dry eye disease (DED) is pervasive with some reports estimating over 16 million adults diagnosed in the United States. Currently, artificial tears remain an integral part of managing dry eyes and are mainly used for symptomatic relief. Recent studies have shown there may be therapeutic benefits with regular use of lipid-based artificial tears to improve the structure of the tear film, which may improve tear film stability and provide relief of symptoms. In this study the investigators propose to compare effects on the tear lipid film and its dynamics between 3 lipid based artificial tears and a widely available non-lipid based artificial tear.
This study will investigate how well OC-01 (varenicline) nasal spray can treat the signs and symptoms of dry eye disease in those Sjogren's Syndrome. Patients at least 18 years old with moderate-to-severe Sjogren's dry eye disease may be eligible for this study. If you are eligible to participate in the study and you decide to join, there will be 3 study visits over approximately 1 month. You will also self-administer the nasal spray at home every day, 2 times a day during this month.
Intense pulsed light (IPL) has been reported to improve signs and symptoms of dry eye (DE). Additionally, meibomian gland secretion of lipids has been observed to improve through the use of IPL. Diquafosol ophthalmic solution (DQS) stimulates P2Y2 receptors on the ocular surface, which enhances mucin secretion from goblet cells. Therefore, tear film stability and hydration of the ocular surface can be achieved independent from lacrimal glands function. The purpose of this prospective study was to evaluate and compare the effects of IPL (IPL group), DQS (DQS group) and IPL in combination with DQS (IPL+ group) in participants with persistent DE. Tear film lipid layer (TFLL), non-invasive breakup time (NITBUT), tear meniscus height (TMH), corneoconjunctival staining score (CS), meibum gland (MG) function, conjunctival hyperemia (RS score), ocular surface disease index (OSDI) will be assessed and compared at baseline, day-14, and day-28.
This is a 30-Day, multi-site, single-masked, bilateral, active- controlled, 2-Arm parallel group study to evaluate the safety and efficacy of an Investigational product.
