Active clinical trials for "Eye Diseases"

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.

The purpose of this research study is to evaluate the efficacy, patient preference, and utility of a novel eye shield that utilizes a different adhesive mechanism in comparison to the current standard of care. The aims are to see if this product could be incorporated into postoperative care in the future to improve patient satisfaction and compliance. The study will involve 20 patients during the postoperative timeframe after cataract extraction and intraocular lens placement (CEIOL). These patients will be chosen from the clinic of Dr. Marc Toeteberg who will plan to have both eye surgeries done within 3 months of each other. These patients will be randomized to either control or intervention group. Intervention group will receive our novel eye shield prototype, while control group will receive an Alcon plastic eye shield. Both groups will receive the eye shields after surgery and will be sent home with these eye shields with normal postoperative care directions. Patient will be directed to wear eye shields for 24 hours then at night for first 2 weeks after surgery, while adhering to postoperative eye drops regimen. After successfully healing and passing the postoperative timeframe for the first eye we will proceed to the second arm of the study. Approximately 1-2 months after healing from the first surgery, patient will be scheduled for cataract surgery on the other eye, as is standard of care. After surgery on the second eye the patient will be given the other eye shield than what they received after the first surgery (control groups will receive the novel eye shield and experimental groups will receive the control eye shield). They will proceed to follow identical postoperative protocols after the second surgery. A short quantitative and qualitative questionnaire directly comparing the two eye shield experiences will be provided at the 1 month follow-up after the eye surgery.

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.

The objective of this study is to assess the safety and feasibility of allogeneic adipose tissue-derived mesenchymal stem cells (ASCs) injected into the lacrimal gland in a smaller groups of 7 patients with Aqueous Deficient Dry Eye Disease (ADDE)

To assess the efficacy and safety of Abatacept as an immunosuppressive treatment in Birdshot uveitis. The primary objective is to test the efficacy to suppress inflammation in active Birdshot uveitis patients, using quantitative and qualitative measurements of visual function.

The purpose of this study is to evaluate the efficacy safety and tolerability of ultevursen administered via intravitreal injection (IVT) in subjects with Retinitis Pigmentosa (RP) due to mutations in exon 13 of the USH2A gene.

This study evaluates the safety, tolerability and efficacy of QR-1123 injection in the eye (intravitreal; IVT) injections (one eye/unilateral) in subjects receiving a single dose or repeat doses. Single injections will be assessed in an open label way, and repeat injections will be assessed in a double-masked, randomized, sham-controlled fashion.

This is a double-masked, randomized, parallel-assignment, multicenter trial examining the safety and tolerability of teprotumumab in the treatment of Thyroid Eye Disease (TED) in adult participants. This international, Phase 3b/4 trial is being conducted to fulfill an FDA post-marketing requirement for a descriptive trial to evaluate the safety, efficacy and need for re-treatment of 3 different teprotumumab treatment durations for TED. In addition, serum samples from participants with a Baseline Clinical Activity Score (CAS) ≥3 will be evaluated for biomarkers of disease.

The purpose of this study is to assess the efficacy and safety of K-161 ophthalmic solution for the treatment of moderate to severe dry eye disease.
