Filter by: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.
A Phase 2, Multi-center, Randomized, Parallel Controlled Study to Evaluate the Clinical Efficacy and Safety of IVIEW-1201 (1.0% Povidone-Iodine) Gel Forming Ophthalmic Solution Compared to Ofloxacin Eye Drops in the Treatment of Acute Bacterial Conjunctivitis
To compare the safety and tolerability of brimonidine tartrate 0.025%/ketotifen fumarate 0.035% combination ophthalmic solution versus its vehicle in healthy adult subjects and in pediatric subjects.
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.
To evaluate the efficacy of Combo compared to its individual components and compared to vehicle in a population of subjects with seasonal allergic conjunctivitis.
To evaluate the efficacy of Combo (Drug Product Brimonidine Tartrate 0.025%/Ketotifen Fumarate 0.035% Ophthalmic Solution) compared to its individual components and vehicle in a population of subjects with allergic conjunctivitis:
The PQGrass306 (G306) clinical trial is the pivotal Phase III efficacy clinical trial of PQ Grass. The aim of the G306 pivotal clinical trial is to confirm the efficacy and safety of the optimal effective dose of PQ Grass 27600 SU. This will be determined through the measurements of the effect of PQ Grass on the symptoms of seasonal allergic rhinitis (SAR)/rhinoconjunctivitis and the use of relief medications to control these symptoms during the peak grass pollen season (GPS).
Ocular surface photography is significantly limited in standardization and reproducibility. This reduces its applicability for clinical monitoring of acute or chronic disease. The innovative lens and illumination design of the CDL system aims to yield standardized high resolution photographs of the cornea and conjunctiva as required for clinical documentation, posing a significant clinical benefit of health care providers in the field of ophthalmology. Primary objectives: The primary objective of this study is to test the safety and feasibility of the CDL imaging system in a clinical routine setting. This will include the comparison of subjective contrast sensitivity testing post imaging, and the measurement of examination duration per imaging session, and the comparison of image lightness in mesopic versus photopic imaging. Secondary objectives: The secondary objective of this study is to compare the image quality of the device and repeatability of lateral resolution, dynamic range, hue, saturation, lightness, and image position between colour photographs from a state-of the art slit lamp camera and the CDL system. This is a monocentric, prospective, observational study. Patients with ocular surface disease of variable aetiology routinely assigned to ocular surface photography, following informed consent, will be imaged using state-of-the-art colour photography and the CDL imaging system. Pictures of each patient will be taken under several standardized conditions with both methods, subsequently analysed and compared by a Medical Image Processing Specialist.

The objective of this study is to evaluate the efficacy of Sasch1, a novel anti-infective eyedrop, in the treatment of acute infectious conjunctivitis.
