Active clinical trials for "Keratoconjunctivitis Sicca"

Meibomian glands are a kind of sebaceous gland located in the tarsus of lower and upper lids and their function is to express lipids to the tear film. The secretion of lipids, polar and no-polar, produced in the Meibomian glands is denominated as meibum and it forms the external layer of the tear film. Its thickness varies from 15 to 200 nm and it is related with the tear film stability and the evaporation of the tear film. The meibum composition is variable among participants, especially in those who suffer Meibomian gland dysfunction or dry eye disease. Meibomian gland dysfunction is the leading cause of ocular surface disease. Meibomian gland dysfunction management depends on its severity, but eyelid hygiene, including warming and expression of Meibomian gland, is recommended from clinical stage 1 and it has proven its efficacy. However, lack of participant compliance can be a problem when this therapy is prescribed. In the last few years, some devices have been developed to improve the efficacy of this therapy, as for example the application of Vectored Thermal Pulsation with the Lipiflow device. It has been reported that low relative humidity values increase evaporative rates in both dry eye participants and healthy participants. Also, our group has extensively proven the negative effect of adverse environments (in the Controlled Environment Laboratory (CELab)) in clinical variables such as tear stability, dry eye symptoms and corneal staining both in healthy and dry eye participants. Therefore, the hypothesis of this study is that improving the Meibomian gland secretion through the application of warm and pressure with Lipiflow device, meibum composition would change in participants with Meibomian gland dysfunction and they would be less affected by adverse environmental conditions simulated in a controlled environmental chamber. The study will try to assess the effect of Lipiflow on the meibum in patients exposed to controlled adverse environmental conditions.

The main purpose of this study is to establish whether RP101 can reduce symptoms of dry eye syndrome in post-menopausal women.

The primary purpose of this study is to determine the efficacy and safety of KPI-121 0.25% ophthalmic suspension compared to vehicle (placebo) in subjects who have a documented clinical diagnosis of dry eye disease. The product will be studied over 14 days, with 1-2 drops instilled in each eye four times daily (QID).

The objective of this study is to evaluate the safety and effectiveness of OC-02 nasal spray compared to placebo on signs and symptoms of dry eye disease (DED).

The purpose of this single-arm pilot study is to evaluate the feasibility and safety of combination therapy of intense pulsed light (IPL) and (Radiofrequency) RF for treatment of Dry eye disease (DED) due to Meibomian gland dysfunction (MGD).

To assess the efficacy and safety of OTX-DED for the short-term treatment of signs and symptoms of dry eye disease.

SURF-100 is being studied for the treatment of dry eye disease. SURF-100 is an investigational drug (which means the study drug is currently being tested) in the form of a sterile eye drop. The purpose of this research study is to see how well SURF-100 works to treat dry eye and what potential side effects there are, and to compare it with Vehicle (placebo), 0.1% mycophenolic acid (MPA) in Vehicle, 0.3% MPA in Vehicle, 0.01% betamethasone phosphate (BSP) in Vehicle, Restasis and Xiidra. This study will involve about 280-350 study participants age 18 and older at about 40 different research sites in the United States.

The purpose of this study is to investigate the safety and effectiveness for applying the electrical stimulation transcutaneously around the eyes and peripheral nerves nearby. The outcomes are compared between the patients with mild- or moderate-level dry eye disease using the real electrical stimulator and the sham electrical stimulator.

The objectives of this trial are to assess the safety, tolerability and efficacy of A197 ophthalmic solution in comparison to a vehicle control in the treatment of subjects with Dry Eye Disease.

In patients with dry eye, defined as corneal staining and a reduced tear breakup time, lifitegrast will improve higher order aberrations, ocular scatter index, corneal staining, and TBUT as soon as 1 week after initiating treatment.
