Active clinical trials for "Meibomian Gland Dysfunction"

AIM: To observe ocular surface changes after phacovitrectomy in patients with mild to moderate meibomian gland dysfunction (MGD)-type dry eye and track clinical treatment response using a Keratograph 5M and a LipiView interferometer. METHODS: Forty cases were randomized into control group A and treatment group B; the latter received meibomian gland treatment 3 days before phacovitrectomy and sodium hyaluronate before and after surgery. The average non-invasive tear film break-up time (NITBUTav), first non-invasive tear film break-up time (NITBUTf), non-invasive measured tear meniscus height (NTMH), meibomian gland loss (MGL), lipid layer thickness (LLT) and partial blink rate (PBR) were measured preoperatively and 1 week, 1 month and 3 months postoperatively.

The purpose of this pilot feasibility study is to assess whether treating meibomian gland dysfunction (MGD) prior to cataract surgery helps promote meibomian gland function, visual quality and ocular comfort after cataract surgery.

The objective of this study was to measure the temperature of the cornea and surrounding eye tissue temperature immediately after heating the eyelids with the iLux device using the protocol treatment profile. Eligible participants attended one treatment visit, with follow-up one day following the procedure.

Minimum 50 eyes and up to 100 eyes will be treated in this prospective, open-label clinical study. The investigator or designee will perform LipiFlow treatment with the Activators LFD-2100 on both eyes of a subject. The data from the treatment reports generated by the LipiFlow console and from the questionnaire will be used to assess the clinical utilization of the Activator LFD-2100. This study will be conducted in up to four sites in the USA.

The pilot study objective is to evaluate the potential benefits of LipiFlow® System treatment of contact lens wearers with meibomian gland dysfunction and evaporative dry eye by assessing for improvement in meibomian gland function and reduction of dry eye symptoms in comparison to an untreated control.

The primary goal of this investigation is to determine if lipid based artificial tear supplementation has an impact on contact lens discomfort (CLD).

Multicentric study, open label, uncontrolled phase IV in 30 patients with meibomian glands dysfunction . Its objective is to Collect information from patients and ophthalmologists specialized in ocular surface and eyelids to anticipate how Blephasteam ® can be optimized. This study involves 2 visits, visit of Inclusion, J0, then end of study visit, D21. Between the two visits patients will be treated with Blephasteam ® for 21 days (up to two uses per day) and complete a questionnaire every two days during the first week and then once a week the next two weeks.

One hundred patients with the diagnosis of posterior blepharitis based on history taking and proper physical examinations by two experienced ophthalmologists will include in the study. Patients will diagnose with posterior blepharitis if they score at least one in two symptoms (based on a subjective grading scale) and two signs (based on an objective grading scale) of posterior blepharitis according to study criteria. Patients will exclude if they have the following criteria: age< 12 years old,history of previous ocular or lacrimal surgery,previous usage of contact lenses,any history of ocular allergy,history of systemic diseases with ocular involvement (except rosacea), history of usage of topical or systemic antibiotic in the last month, pregnancy or lactating mothers, liver failure and any history of sensitivity to cyclines. Qualified patients then randomly receive oral azithromycin (2 of 250 mg capsules for the first day and 250mg for the next 4 days) or oral doxycycline (100mg capsule every 12 hours for one month) in a double-blinded fashion. each patients in both treatment groups will accurately instruct to apply warm compress and eyelid scrubbing 2 times a day for 5 minutes each in the treatment period. Symptoms and signs were recorded for each patient in two treatment groups at baseline visit (before treatment) and then in the days 7, 31, 37 and 61 after treatment.

Meibomian glands (MG) are modified sebaceous glands associated with the tarsus (collagenous structural component) of the upper and lower eyelids. Meibomian glands produce lipid-based secretions which are an integral and stabilizing part of the tear film. In blepharitis and ocular rosacea (two known causes of obstructive meibomian gland dysfunction (o-MGD), inflammation of the lid margins causes blockage of the meibomian gland orifices, changes in glandular secretions, and dropout of the glands themselves. This limits the production, secretion, and quality of meibum. With less oil in the tear film, the aqueous portion of tears is not stable and evaporates quickly which leads to dry eye.

This study will compare cataract patients before and after phacoemulsification. Evaluations will be performed before and 1 and 3 months following cataract surgery, including parameters of dry eye syndrome and MGD. Dry eye syndrome parameters included TBUT, Schirmer's test type I, Oxford staining score, and the Ocular Surface Disease Index (OSDI) Questionnaire. MGD parameters consisted of lipid layer thickness (LLT), lid margin abnormality, meibum quality, meibum expressibility, MG orifice obstruction, MGD stage, and MG dropout.
