Filter by:Dry eye disease remains one of the most common complaints seen in ophthalmic clinics. Causes of dry eye are multifactorial, with the most common cause of evaporative dry eye disease being meibomian gland dysfunction (MGD). Fingerprick autologous blood (FAB) is a novel method which uses a patient's own blood to treat dry eye conditions.
The LipiFlow System (TearScience, Morrisville, NC) is an in-office FDA approved treatment for meibomian gland dysfunction. It relieves meibomian gland obstruction through the use of heat and pulsatile pressure. A recent study has observed that a single treatment with the LipiFlow system can decrease dry eye symptoms and objective findings of meibomian gland dysfunction for 1 year. We aim to see if the Lipiflow System will be beneficial in patients with Parkinsons disease who may have difficulty performing normal meibomian gland dysfunction treatment.
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.
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.
In this study, investigator aim to evaluate the changes of tear-film lipid layer thickness and ocular aberration after treatment of meibomian gland dysfunction. In case of stage 3 or 4 meibomian gland dysfunction, participants will be treated using conventional treatment modalities. Before treatment and after 1 and 2 months of treatment, a variety of ophthalmic examination, tear-film lipid layer thickness, and ocular aberration are going to measured and compared.
Infrared meibography is a useful technique in the evaluation of meibomian gland disease (MGD). MGD is a major cause of dry eye symptoms, affecting a large number of patients seen in the Corneo-Plastic Unit (CPU). Many parameters have been used to evaluate MGD including tear film break-up time, lid margin abnormalities, and Schirmer tear test values. Direct visualization of meibomian glands by infrared meibography has been shown to correlate well with these parameters. Although infrared meibography was developed more than 30 years ago, it is not widely used. This has probably been due to the need for special equipment, examiner time and expertise and patient discomfort during the examination. Analysis of the acquired images also needed to be from video review with extraction of video stills - a time-consuming process. Investigators aim to pilot a rapid non-contact (non-painful) method of obtaining infrared images of meibomian glands using equipment already available at QVH. This pilot study will validate the technique and check patient acceptability. Investigators are hopeful this test could be used as a useful tool for future research into dry eye conditions and MGD.
In this research study, the investigators are looking at the effects of Meibomian Gland Probing (MGP) versus a sham (fake) procedure in patients with refractory MGD who have already tried traditional management with no success in resolving their clinical signs (as seen by their ophthalmologist) or their symptoms. The investigators are also evaluating the effects of using two (2) post-procedural medication treatments: Blephamide or GenTeal PM Night-Time to determine if treatment after the MGP procedure has an effect on its outcome.
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.
Meibomian gland dysfunction (MGD) is a common and important disease has been investigated the pathophysiology, diagnosis, treatment modalities of MGD, however, the changes of MGD after the cataract surgery, the most popular surgery to ophthalmologist, had not been evaluated. The investigators evaluated parameters related with MGD including lid margin abnormalities, meibomian gland expressibility and meibography before and after surgery.
Our primary aim is to determine whether pulsed light therapy (PLT) is effective in reducing symptoms and improving clinical stigmata of dry eye syndrome (DES) associated with meibomian gland dysfunction (MGD) in patients with facial rosacea (which includes ocular rosacea). The uses of PLT are for treatment of rosacea, hair removal, pigmented lesions, and skin telangiectasias. The risks include the potential for transient sunburn-like sensations (i.e. redness, burning sensation) and particularly if not used properly, the potential to cause burns, blistering, scarring, and pigmentary changes.
