Filter by:Primary Sjögren's syndrome is a chronic autoimmune disease that primarily involves exocrine glands, most commonly manifested in dry eye, dry mouth, and in other systems of the body.
In recent years, many scholars have studied the ocular surface damage of patients with dry eye disease（DED）after FS-LASIK, but there has been a lack of comprehensive observation and research on the relationship and difference between dry eye （DE）patients with and without LASIK. Therefore, the purpose of this study was to investigate the characteristics of ocular surface and cytokines after FS-LASIK, and further explain the pathogenesis of chronic dry eyes after FS-LASIK. In addition, we will also compare clinical characteristics and tear neuropeptide concentrations in patients with dry eye disease (DED) with and without chronic ocular pain following FS-LASIK, and to investigate correlations between ocular pain, clinical characteristics, and tear neuropeptide levels.
Proposed Study Title: Prevalence of Different Etiologies of Ocular Dryness in Patients Previously Diagnosed with Dry Eye
The aim of this study is to assess the effect of intense regulated pulse light (IRPL) on the treatment of Dry eye.
To determine if electroacupuncture acts as an dry eye treatment rather than a placebo, and identify if benefits are linked to corneal subbasal nerve changes and neuroimmunomodulatory indicators.
A randomized, controlled, double-masked, investigator-initiated trial to evaluate tear film quality and stability in subjects with dry eye disease using OC-01 (varenicline solution) nasal spray 0.03 mg as compared to vehicle control nasal spray.
The Rexon Eye device (Resono Ophthalmic Inc, Trieste, Italy) is a new device based on QMR technology. Quantum Molecular Resonance (QMR) is a technique in which low-intensity, high-frequency electric currents are administered to a biological tissue through contact electrodes. The device applies stimulation to the epidermis of closed eyelids up to the lid margin by means of specially designed goggles. Previous studies have shown that it is relatively safe with high patient satisfaction. Preliminary studies have also shown it is effective for accelerating healing in chronic wounds and treating dry eye symptoms.
The primary objective is to determine possible implications of deviant tear film quality for optimal refractive precision in patients scheduled for cataract surgery. The study consist of three separate arms where cataract patients will be separated in to Dry Eye Disease (DED) positive and negative groups. The DED positive group will be further subdivided into two different treatment groups (with focus on prolonged use of lubricant and preservative free eye drops). Tear film samples will be taken before treatment, after treatment and after surgical treatment and compared.
The main objective of our study is to evaluate the effect of eye drops with antioxidants on mild to moderate dry eye symptoms in patients with diabetic retinopathy, evaluating the levels of inflammatory cytokines and oxidative stress in the tear film. The researchers intend to include 78 patients, divided into three intervention groups, who will be randomly assigned an eye drop with antioxidants, where the patient must apply one drop in each eye for 1 month. In the study, the characteristics of the surface of the eye will be evaluated and tear samples will be taken from each eye, before and after the intervention with the eye drops. Subsequently, the clinical and sample results will be evaluated to compare the effects between them.
Hyaluronic acid (HA), a natural component of the tear film, is a well-established active ingredient in artificial tears and has been reported to improve corneal and conjunctival staining in patients with DED. Thealoz Duo (Laboratoires Thea, Clermont Ferrand, France) is a novel artificial tear preparation containing two active ingredients: trehalose, a naturally occurring disaccharide with anhydrobiotic functions in many organisms, and hyaluronate, a widely distributed anionic glycosaminoglycan polysaccharide with lubricative and water-retaining properties in biological systems. The purpose of the current study is to investigate the effect of the Hyabak and Thealoz Duo in treatment of DED.
