Dry Eye and Meibomian Gland Dysfunction

“Dry eye is a disorder of the tear film due to tear deficiency or excessive evaporation, which causes damage to the interpalpebral ocular surface (ie the exposed surface of the eye) and is associated with symptoms of ocular discomfort.”

This elegantly straightforward definition by the Classification Sub-committee of the International Dry Eye Work Shop (2007) describes a problem that can be anything from an intermittent nuisance to a blinding condition.

Diagnosis is often less than straightforward, due particularly to the difficulty in differentiating between situations which are due to Primary Tear Deficiency and those that are secondary to Meibomian Gland Dysfunction. This latter is possibly the most common cause dry eye - and certainly has been the most challenging to treat.

I have special expertise in managing ocular inflammation and have expertise in the new treatments now available for Meibomian Gland Dysfunction (see below). I employ specialised investigation techniques to identify the cause of the problem and follow a semi-rigid step-ladder approach to treatment.

Recent innovations in managing dry eyes and Meibomian Gland Dysfunction include surgery to conserve tears and, more recently, Intraductal Meibomian Gland Probing, which has been shown to relieve symptoms of obstructive Meibomian Gland Dysfunction.
