Active clinical trials for "Dry Eye Syndromes"

This will be a 12-month, multicenter, vehicle-controlled, double-masked, randomized Phase 3 study conducted at approximately 10 sites in the United States. All subjects enrolled will have dry eye disease (DED). The study will consist of a Baseline (Day 1) visit as well as visits at Day 14, Day 90, Day 180, Day 270, and Day 365 (Study Exit).

To demonstrate the safety and effectiveness of TearCare® procedures compared to Restasis® to treat the signs and symptoms of dry eye disease in adult patients.

The study objective is to assess the efficacy and safety of cenegermin (rhNGF) ophthalmic solution at 20 mcg/mL concentration administered three times daily for 4 weeks in patients with severe Sjogren's dry eye disease.

A Randomized, Masked (Evaluator), Controlled, Prospective Study Evaluating the Effectiveness and Safety of the Tixel® Medical Device, Versus LipiFlow® in the Treatment of Meibomian Gland Dysfunction

The purpose of this interventional study is to assess safety, patient tolerability, plug retention rate, and preliminary efficacy in improving the symptoms of Dry Eye Disease (DED) of EXP-TC tacrolimus releasing punctal plug. The main questions it aims to answer are: The safety of using EXP-TC plug following all study adverse events The number of patients with Adverse Events related to the us of EXP-LP plug The number of patients discontinuing the study due to plug discomfort The total patients with plugs remained during the 3-months study duration from plug insertion Exploratory: change from baseline in the study eye to follow-up visits in various Dryness clinical measurements. The change of measurements from baseline will also be compared between the study and fellow control eye (receiving artificial tears only, 0.15% sodium hyaluronate).

This will be a Phase 3, multicenter, vehicle-controlled, double-masked, randomized study conducted at approximately 20 sites in the United States. All subjects enrolled will have dry eye disease (DED). The study will consist of Screening (Day -14) and Baseline (Day 1) visits as well as visits at Day 7, Day 14, Day 28, and Day 90 (Study Exit).

The aim of this study is establish the reliability and clinical utility of microneuromas as identified via in vivo confocal microscopy as the diagnostic biomarker for NCP.

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.

This study aims to profile the ocular surface inflammation of chronic Graft-Versus-Host Disease patients by investigating conjunctival cells, and clinical imaging for conjunctival redness and tear stability. Hence, the investigators expect to find an increased in inflammatory cell population in GVHD conjunctival samples.

Ocular surface disease, especially dry eye and scleritis, commonly affects patients with autoimmune diseases. Ocular surface immune cells are increased in autoimmune disease; however the full subset of immune cells activated is unknown. Recent experimental studies show that dendritic cells and T cells in the cornea are critically associated with corneal nerve innervation. Corneal confocal microscopy (CCM) allows rapid non-invasive in vivo imaging of dendritic cells and corneal nerves. The investigators propose to investigate how ocular surface health, conjunctival immune cells and corneal nerve/dendritic cell morphology interact in 3 rheumatological conditions: Sjogren's syndrome (SS), Rheumatoid arthritis (RA), Systemic lupus erythematosus (SLE). The preliminary flow cytometric studies show that various immune cells (eg: T cells, B cells, and dendritic cells) can be quantified using minimally invasive impression membranes (Eyeprim). Clinically, the research team is experienced in measuring features of ocular surface inflammation (conjunctival redness, tear breakup times) with Oculus keratograph5M. The investigators also aim to harvest conjunctival immune cells using impression cytology and quantify specific cell types with flow cytometry. Corneal nerve morphology and dendritic cell density and distribution will be assessed using CCM; in collaboration with the group who have pioneered this technique. The investigator anticipate that alterations in corneal nerve and dendritic cell parameters will correlate with immune activation/inflammation, deterioration of tear function and increased systemic severity of the rheumatological disease. In addition, the investigators hypothesize that the lower the corneal nerve density, the higher the number of corneal dendritic cells and conjunctival inflammatory cells. Studying these relationships may allow a better mechanistic understanding of local corneal and systemic immune activation and the development of a non-invasive ophthalmic surrogate marker of dendritic cell activation and nerve fibre loss to aid earlier diagnosis, risk stratification and the development of new therapies in autoimmune patients with severe dry eye.
