Information about Meibomain Gland Dysfunction
Meibomian glands are the oil-producing glands located in both the upper and lower eyelids. They number about 25 to 30 and normally slowly release oil into the tear film. This oil helps to stop the water in the tears from evaporating, thus helping to prevent dry eyes.
Sometimes the oil becomes slightly thicker than normal which can lead to blockage of the narrow duct which takes the oil from the gland to the tear film. The oil continues to be made and this can lead to filling and swelling of the glands, in addition to causing a dry eye, since the stabilizing oil cannot reach the tear film. Severe blockage can lead to much enlarged glands (a cyst) or even infection. It is therefore important to firstly, unclog the glands which are blocked and secondly to prevent them from blocking up again as much as possible. Omega - 3 or fish oils also help people with MGD and are recommended to be taken with a cold drink an stored in the fridge. In addition to warm compresses commercial preparations may be recommended, such as Sterilid Foam and Lidcare wipes. |
