Active clinical trials for "Dry Eye Syndromes"

The primary objective of this study is to show that CEQUA (cyclosporine 0.09% ophthalmic solution) improves symptoms of dry eye disease in a population of patients with Sjogren's Syndrome diagnosis.

The purpose of this study to evaluate changes in comfort and dryness in symptomatic contact lens (CL) wearers after using Xiidra (lifitegrast 5.0% ophthalmic solution) for 12 weeks.

The goal of this clinical trial is to evaluate the effectiveness of Low Level Light Therapy (LLLT) in reducing the incidence or alleviating the severity of DED due to meibomian gland dysfunction in otherwise healthy patients undergoing cataract surgery. Participants will be randomly assigned in a 1:1 ratio to either a treatment group or a control group. The treatment group will receive LLLT one week before and one week after cataract surgery; the control group will not recieve LLLT at any time. Researchers will compare the treatment and the control group to see if patients receiving LLLT present with reduced signs and symptoms of ocular surface dysfunction with respect to the control group.

This study is designed to learn more about the impact different types of stimuli, such as heat, cold and vibration, can have on ocular pain response. This is called quantitative sensory testing (QST). Most procedures being performed in this study, except the QST, are standard of care which means they are performed during the participant's routine eye examination.

Study Rationale: The glaucomas are a group of optic neuropathies characterized by progressive degeneration of retinal ganglion cells. These are central nervous system neurons that have their cell bodies in the inner retina and axons in the optic nerve. Degeneration of these nerves results in cupping, a characteristic appearance of the optic disc and visual loss. The biological basis of glaucoma is poorly understood and the factors contributing to its progression have not been fully characterized. Glaucoma affects more than 70 million people worldwide with approximately 10% being bilaterally blind, making it the leading cause of irreversible blindness in the world. Glaucoma can remain asymptomatic until it is severe, resulting in a high likelihood that the number of affected individuals is much higher than the number known to have it. The tear film is fundamental in the maintenance of the ocular surface. Any condition that adversely affects the stability and function of the tear film such as dry eye symptom, blepharitis, and meibomian gland dysfunction, dysfunctional tear film syndrome, or toxicity of topical medications may result in onset of an ocular surface disease (OSD). The symptoms of OSD may include dryness, burning or stinging, itching, irritation, tearing, photophobia, foreign-body sensation, grittiness, redness, fatigue, fluctuating visual acuity, and blurred vision. OSD is a common comorbidity in glaucoma patients in part due to the fact thatits prevalence as in glaucoma increases with age. OSD is seen in approximately 15% of the general elderly population and is reported in 48% to 59% of patients with medically treated glaucoma. One in six patients with glaucoma has OSD symptoms severe enough that they need some form of treatment. Ophthalmic solutions with soothing and refreshing proprieties, as addon treatment to glaucoma therapy, could relieve the OSD symptomatology, dry eye like, in glaucoma patients, improving their quality of life. For these reasons, an interventional, confirmative, post marketing clinical followup (PMCF) study was planned to evaluate the performance and safety of ophthalmic solutions used to relieve dry eyes like symptoms in glaucoma patients. Study Objective: The objectives of this 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 three investigational products (IPs). The IPs are on the market with the following brand names: Afomill Refreshing Soothing Afomill Anti-redness Eye Drops Iridil

This prospective study will evaluate the effect of oral sunflower lecithin dietary supplementation on meibomian gland function in adults with dry eye disease.

Patients who suffer from dry eye disease are often prescribed eye drops containing cyclosporine A that help with reducing inflammation. The newest eye drop containing cyclosporine A is called Cequa (Sun Pharma, Canada). Unfortunately, nearly a quarter of (24.2%) of patients using Cequa have reported some form of discomfort (burning and stinging) when instilling the drops. This potentially discourages patients from continuing the eye drop, which prevents their dry eye disease from being managed effectively. This study is trying to determine if refrigerating the eye drops would allow the drops to feel more comfortable when they are instilled in the eye.

Dry eye disease (DED), also called keratoconjunctivitis sicca, is a multifactorial disease of the ocular surface characterized by loss of homeostasis of the tear film and accompanied by symptoms such as ocular discomfort and visual disturbance. The reported prevalence of DED estimates vary widely, from 5% to 33%, which may reflect both differing populations and inconsistent diagnostic criteria. Patients with moderate-to-severe DED may experience a reduced quality of life due to ocular pain, difficulty in performing daily activities, and depression. First-line therapy for treating dry eye consists of over the counter (OTC) artificial tear drops, gels, ointments, or lubricants. Sodium hyaluronate (commonly referred to as hyaluronic acid or HA) is a naturally occurring polymer and is ubiquitous throughout the interstitial cellular space in humans. It helps retain moisture in different types of tissue throughout the human body and aids lubrication between layers of tissue to eliminate friction - thus making it an ideal physiological tear film substitute. As a result of its coiled structure and large hydrophilic domains, HA attracts and retains a large amount of water, and therefore possesses the ability to retard water evaporation. Following instillation, HA-based solutions effectively moisturize the eye surface and prolong the beneficial wetting effect over time. Hyaluronic acid does not alter the normal surface of the eye like other types of tear substitutes. It closely mimics the properties of a normal, healthy tear film, with a longer retention time on the corneal surface than a cellulose-based tear substitute. HA gels have also been used successfully in ophthalmic surgery for many years. As a result of their unique physical and chemical properties, HA solutions are similar to natural tears. For that reason, they are widely used in ophthalmology as lubricant eye drops for the treatment of sensations of ocular dryness. For these reasons, an interventional, confirmative, post marketing clinical follow-up (PMCF) study was planned to evaluate the performance and safety of HA-based ophthalmic solutions (i.e. Irilens; Iridina; Afomill Lubricating Eye Drops) used to relieve dry eyes symptoms. The objectives of this 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 three investigational products (IPs) containing HA as key ingredient. The IPs are on the market with the following brand names: Irilens; Iridina; Afomill Lubricating Eye Drops. Primary • To evaluate the performance of IPs used as intended to relieve dry eye symptoms. Secondary To evaluate the efficacy of IPs used as intended to relieve symptoms of DED. To evaluate the safety and tolerability of the IPs. To evaluate the patient satisfaction of the IPs.

Benzalkonium chloride (BAC) is a preservative, which is a component of more than 70% of topical ophthalmic drugs. Although BAC is a preservative with an excellent antibacterial spectrum, it has also been shown to induce toxic effects to the ocular surface. Several studies have indicated that BAC may also have altering effects on the bacterial flora of the conjunctiva. Since dry eye syndrome (DES) is a very common and multifactorial disease of the ocular surface and the tear fluid resulting in tear film instability, inflammation of the ocular surface, symptoms of discomfort and visual impairment, there are many different preserved as well as preservative-free ophthalmic preparations of ocular lubricants for the treatment of DES. Unpublished data from our department shows differences between artificial tears for the treatment of DES with and without BAC in bacterial culture. Therefore, the aim of this study is to investigate the effect of artificial tear eyedrops with and without BAC on the conjunctival bacterial flora. For this 40 patients with mild or moderate dry eye syndrome with no use of artificial tears in the 4 weeks preceding the study will be recruited and treated either with the preservative-free "Prosicca sine" eyedrops or the BAC containing "Prosicca" eyedrops for one month. Conjunctival samples will be collected of one eye of each patient before and after the 1-month treatment period to compare the conjunctival bacterial flora of the two treatment groups.
