The eye is your window to the world and is responsible for supplying you with the majority of information around you. So what happens when that window becomes compromised and using it causes discomfort and there is a risk of it becoming unusable?

Dry eye by definition is a multi-factorial disease of the tears and ocular surface. It is more common in women, contact lens wearers, those with glaucoma and persons living a modern lifestyle and use digital devices. During the day a person may experience burning, watering eyes, a foreign body sensation, red eyes and have fluctuating vision.

Tears are made up of three main components and when the balance is off this spells disaster. The tears help oxygen to reach the cornea, defend the eye against bacteria and lubricate the eye surface. In most cases of dry eye it is the lipid layer that is in short supply due to meibomian gland disorder (MGD). MGD cannot be cured, it is managed like gum disease, with persons being made to feel more comfortable. Left untreated for a long time there is risk of dry spots becoming scars leading to blindness.

Treatments range depending on the severity of the condition and are aimed at enhancing the system Mother Nature has made. Options may include artificial tears, light therapy, therapeutic expression of the glands or punctal plugs. Supportive therapy can be warm compresses, lid scrubs topical medication for inflammation and fish oil supplements as well as sleep goggles. Proper blinking is critical to maintaining the health of the meibomian glands and ocular surface. Dry eye symptoms are progressive in nature so the sooner treatment is started the better the long term outcome.
