Active clinical trials for "Meibomian Gland Dysfunction"

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

In this randomized clinical trial, patients with Meibomian gland dysfunction aged 50 year and more will be enrolled. The Meibomian gland dysfunction diagnosis will confirmed by a cornea specialist. The enrolled patients will be randomly allocated to the treatment and placebo group. The patients in treatment group will receive topical vitamin D every 6 hours daily (25 Microgram/cc or 1000 IU). The control group will receive the same-shape packed drop without vitamin D. The patients in both group will receive the conventional treatment including hot compress and shampoo scrub. The primary outcome is the change in Ocular surface disease index and 5-Item Dry Eye Questionnaire score assessed before the topical treatment and every one-months until 3 months. The secondary outcome measures are Tear breakup time, Schirmer test, Corneal fluorescein staining, Meibomian gland expressibility. The grader and the patients will blind to the study group.

The purpose of this study is to compare electronic debridement of the eyelid margin (BlephEx) to manual debridement of the eyelid margin as treatment options for patients intolerant to contact lens wear consequent to Meibomian gland dysfunction.

Dry eye disease is a common condition affecting millions worldwide and costing millions in healthcare due to reduced work productivity and quality of life. The disruption of oil glands in our eyelids known as Meibomian glands, which produce the oily layer of our tears to protect it from evaporating, is one of the most common contributors of dry eye disease. Much effort has been put into developing effective treatments for this condition as new treatments are constantly being introduced to the market. The purpose of this clinical trial is to investigate how proven light-based therapies work in treating dry eye disease and oil gland disruption. These therapies include intense-pulsed light therapy (IPL) which uses a series of light flashes on the facial skin surface, and low-level light therapy (LLLT) which uses a mask with a series of light-emitting diodes (LEDs) to warm the body cells. The main questions it aims to answer are: What are the short- and long-term changes associated with these treatments on the eyelids and surface of the eyes? Does LLLT alone work better than IPL+LLLT in treating dry eye disease and oil gland disruption? Participants with dry eye disease and oil gland disruption will receive four treatments with these light-based therapies each separated by two to three weeks apart, and followed up two to three weeks and three months after the final treatment session. One eye of the participant will receive intense pulsed light together with low-level light therapy, while the other eye will receive only low-level light therapy with a sham intense pulsed light treatment so that the researchers can compare if clinical signs and symptoms improve in one eye more than the other.

This study is a multicentric, comparative, randomized, investigator-blinded, in parallel groups study to demonstrate the non-inferiority of Neovis® Total Multi in comparison with Systane® Balance, in terms of improvement of stability of Tear film in patients with eye dryness associated to meibomian gland dysfunction, after 28 days of treatment.

The development of optical coherence tomography (OCT) and its application for in vivo imaging has opened entirely new opportunities in ophthalmology. The technology allows for both noninvasive visualization of the morphology and measurement of functional parameters within ocular tissues to a depth of a few millimetres even in nontransparent media. Until now the resolution of commercially available OCT systems is, however, much lower than that provided by light microscopy. Recently, an ultrahigh-resolution OCT system was developed by our group providing resolutions of 1.7 and 17 µm in axial and lateral direction, respectively. This axial resolution is about four times better than that provided by standard OCT systems. It allows to perform in vivo imaging with a resolution close to biopsy of tissue and to visualize structures of the anterior eye segment with a remarkable richness of detail. The prototype was applied for in vivo imaging of the cornea including the precorneal tear film. The goal of the planned pilot study is to apply this innovative imaging modality for visualization of the ultrastructure of the different parts of the anterior eye segment structures in diseased subjects, as well as in patients who underwent minimally invasive glaucoma surgery (MIGS). The obtained in vivo cross sectional images and three-dimensional data sets are hoped for contributing to the knowledge about the anatomy and physiology of the corresponding tissues. This could allow for a better interpretation of clinical features and findings obtained in slit lamp examination.

Proposed Study Title: Prevalence of Different Etiologies of Ocular Dryness in Patients Previously Diagnosed with Dry Eye

The objective of this study is to establish whether patients with dry eye disease (DED) are able to tolerate receiving Brimonidine: 0.15% eye drops two times a day for twelve weeks (primary tolerability objective) and to investigate the preliminary efficacy of Brimonidine 0.15% topical eye drop solution in treating Meibomian Gland Dysfunction (MGD) (primary efficacy objective). Meibomian Gland dysfunction can happen with numerous conditions such as Rosacea, Sjögren's syndrome, and oGVHD. In order to limit the influence of differing etiologies on the outcome of this trial, the investigator has limited the screening to MGD that accompanies oGVHD.

The purpose of this prospective study is to evaluate the benefits of using the Bruder Moist Heat Compress in contact lens wearers who report reduced comfortable wear time. This will be done by assessing for improvement in ocular oil gland function and comfortable contact lens wearing time after one month of daily warm compress application. The efficacy of the Bruder Moist Heat Compress applied once will be compared to twice daily application as well as compared to warm compress application using a wash cloth.

Along the edge of the eyelids, there are glands (meibomian glands) that produce and deliver oils (meibum) onto the tear film. These oils serve to slow down the evaporation of tears. The meibomian glands may become obstructed due to change in meibum quality. When meibum thickens and solidifies, it plugs the gland openings and oils can no longer reach the tear film. The blockage of the glands is the primary cause of meibomian gland dysfunction (MGD), and may result in symptoms of dry eye (burning, stinging, grittiness, etc.). The typical treatment for MGD is a procedure called "warm compresses". It is a combination of applying heat and pressure to the eyelids for approximately 10 minutes to melt the meibum, unplug the gland openings, and allow oils to flow normally onto the tear film once again. One way to apply heat to the eyelids is by using the MGDRx® EyeBag. The EyeBag is microwaved for 30-40 seconds under full power, and is placed over the closed eyes for approximately 10 minutes. The eyes are gently massaged afterwards. The purpose of this study is to determine how effective the EyeBag is at improving MGD and dry eye symptoms.
