Filter by:The modern treatment of meibomian gland dysfunction(MGD) is based on anti-inflammatory drops or oral antibiotics for decreasing dry eye disease (DED) associated inflammation, warm compresses for liquefying the thicker meibum, and lid hygiene for reducing the bacterial overload. But, such treatments have shown limited effectiveness to a large proportion of patients with MGD, due to the multifactorial background of the disease. Thus, alternative approaches aiming at different aspects of the DED pathophysiology are needed. Elimination of posterior lid-margin hyperemia with telangiectasia could be a treatment target for reducing the secretion of inflammatory mediators in the course of MGD. Using the mechanism of photocoagulation via selective thermolysis, laser light could contribute to the destruction of abnormal vessels at the posterior lid-margin and thus, the reduction of inflammation. Recently, sub-threshold (micropulse) laser photocoagulation was introduced in ophthalmology and offers significant clinical advantages compared to conventional continuous wave (CW) approach, preventing laser induced thermal damage and related treatment side effects. This study investigates the effect of sub-threshold (micropulse) laser treatment for dry eye disease due to meibomian gland dysfunction combined with increased eyelid margin vascularity.
Dry eye is one of the most common ocular surface diseases. Its pathogenic factors are related to multiple etiology. Because of the complexity of the pathogenesis of dry eye, the diversity of related examinations, and the inconsistency of symptoms and signs of dry eye patients, the diagnosis of dry eye has higher requirements on the professional technology and examination equipment of ophthalmologists. The purpose of this study is to establish a case-control cohort of dry eye patients. Multimodal data will be collected from participants, including medical history information, ocular surface disease index scale (OSDI), anterior segment photography, and treatment outcome of dry eye patients. The correlation between the characteristics of anterior segment images and dry eye diagnosis will be explored by artificial intelligence algorithms. The purpose of this study was to develop an artificial intelligence dry eye screening and referral system.
This is a phase 3 study to evaluate the safety and efficacy of OmegaD softgels for the treatment of dry eye disease. A daily dose of 2 OmegaD softgels dosed orally BID will be compared to 2 placebo softgels (mineral oil ) dosed orally BID for 84 days. Approximately 300 subjects will be evaluated for their signs and symptoms of dry eye disease and for safety throughout the study.
The objective of the study is to evaluate the long-term clinical utility, safety, and effectiveness of re-treatment with the TearCare™ System in adult patients with dry eye syndrome who had previously been treated with the TearCare System.
Dry Eye Disease (DED)is a chronic disease without a cure. Empowering patients to engage in better self-care requires knowledge of their disease and skills in self-management, which can lead to improved well-being and quality of life. The Investigation team has developed a DED self-management program (video series and educational booklet) that can be easily implemented into clinical use. The Investigators are going to use the Ocular Surface Disease Index (OSDI) to measure the dry eye in the participants. In addition, the research team plans to use the heiQ (validated questionnaire that assesses self-management and health education programs) to evaluate the DED self-management program by comparing results taken at baseline to 2 months after undergoing the self-management program.
The primary aim of the study is to investigate whether optical coherence tomography (OCT) may be a useful tool for investigating the in-vivo histology of ocular structures in patients with tear film pathology. In epiphora the investigators will image the proximal lacrimal system. In dry eye syndrome the investigators will image the lacrimal gland and also the buccal mucosa. The secondary aim of the study is to investigate the appearance of the normal cornea and conjunctiva under OCT imaging.
This is a randomized, double masked study designed to evaluate the safety of EBI-005 5 mg/mL topical ophthalmic solution given three times daily (TID) compared to vehicle-control over a one year period in subjects with dry eye disease (DED). Approximately 188 subjects will be enrolled to either EBI-005 or vehicle at up to 15 centers in the United States (US) and Canada.
The specific aims of the the investigators studies are as follows: - To collect the tear samples from patients with different ocular surface disorders, including SLK, conjunctivochalasis, and keratoconjunctivitis sicca (KCS). - To evaluate the differential expression of tear cytokines and pH values between different ocular surface disorders. - To collect the surgical conjunctival specimens from the patients with SLK and conjunctivochalasis. - To evaluate the factors inducing mast cell migration and how mast cell is activated in SLK via surgical specimens and cultivated fibroblast.
The VITamin D and OmegA-3 Trial (VITAL; NCT 01169259) is a randomized clinical trial in 25,875 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study is being conducted among participants in VITAL and will examine whether omega-3 fatty acids or vitamin D3, compared to placebo, reduce the incidence and/or progression of dry eye disease.
This study evaluates the use of topical cyclosporine 0.05% and sodium carboxymethylcellulose 0.5% for the treatment of dry eye disease in patients infected with the human immunodeficiency virus. Twenty HIV-positive-patients were selected from the Department of Infectious Diseases of the Federal University of Rio de Janeiro Hospital. Dry eye diagnosis was based on a dry eye questionnaire (Ocular Surface Disease Index - OSDI®), Schirmer I Test, break up time and 1% rose bengal staining of the ocular surface. The patients were divided into two groups with ten patients. Group I received sodium carboxymethylcellulose 0.5% drops and group II received sodium carboxymethylcellulose 0,5% drops and topical cyclosporine 0.05% for six months.
