Dry eye syndrome is considered one of the most important ophthalmologic diseases, affecting 10 to 20% of the general population. Of these, 3.7% to 70% of cases are due to meibomian gland dysfunction (MGD). MGD is a chronic diffuse disease characterized by terminal duct obstruction and/or qualitative/quantitative changes in gland secretion. This causes a disruption in the tear film, ocular irritation symptom, inflammation, and ocular surface symptoms. The gold standard for the treatment of meibomian dysfunction is the use of warm compresses and eyelid massage 2 times a day. These have variable results and consequently patient's adherence to treatment is low. An alternative treatment is the use of thermal therapy devices such as Lipiflow, MiBo Thermoflo, and Blephasteam. The objective of this study is to determine if the thermal device MiBo Thermoflo is more effective than warm compresses and eyelid massage in the treatment of dry eye secondary to MGD. Participants will be randomly assigned to one of two groups: the Mibo group will receive 3 sessions of thermal therapy at 2 weeks interval and the control group warm compresses and eyelid massage 2 times per day. All subjects will have follow up of 24 weeks and we will compare results for both groups at the end of the study. During the protocol patients in both groups will continue with their standard treatment for dry eye as needed.
Dry eye syndrome is a common eye disease that affects 1 to 2 out of 10 persons around the planet. One common cause of this disease is the meibomian gland dysfunction. Meibomian glands are very small glands located at the rim of the eyelids that produce an oily substance that prevents the evaporation of tears. When these glands are compromised, the tear film evaporates quickly and the eyes dry up. This disease presents as eye irritation, foreign body sensation, inflammation, etc. The treatment of choice for MGD is eyelid massage and warm compresses 2 times a day. However, these treatments not always work perfectly, and as a result, patients find it hard to follow doctor's orders. Another kind of treatment is thermal therapy. There are several devices that are designed to apply heat on the eyelids, such as Lipiflow, MiBo Thermoflo, and Blephasteam. In this study, we want to find out whether thermal therapy with MiBo Thermoflo works better than warm compresses and eyelid massage use in the treatment of dry eye caused by MGD. To do this, we will select several patients and will assign them randomly to either the group with thermal therapy with MiBo Thermoflo or to the group with warm compresses and eyelid massage. The Mibo group will receive 3 sessions of thermal therapy at 2 weeks interval and the control group warm compresses and eyelid massage 2 times per day. All subjects will have a follow up of 24 weeks and we will compare results for both groups at the end of the study.
