Dry Eye Treatment

To diagnose and treat dry eye, we incurporate a noninvasive advanced technology instrument called keratograph 5M. This technology help our optometrists in North York, ON to plan a precise treatment accordingly. This technology also is a great educational tool for our patients to understand the root cause of their dry eye and therefore to increase the rate of compliance.

Dry eye is a chronic and progressive eye disease, if left untreated it may become so severe that interfere with work and normal activities and damage the cornea.

Dry eye is a multifactorial disease of the tear glands and ocular surface that causes symptoms of discomfort such as irritation, gritty, scratchy, itchy, blurred vision and excess tearing.

What is Dry Eye?

In a healthy eye, tears are responsible for the perfectly smooth ocular surface which allows clear vision. Tears also clean and lubricate the eye. Every time we blink, a fresh layer of tears, called the Tear lm, spreads over the eye. The Tear film is important for keeping the eye moist and comfortable and also to create a smooth optical surface on the cornea to provide a clear vision. Sometimes, the eye may stop producing enough tears or tears evaporate too quickly. This common and often chronic condition is referred to as dry eye syndrome.

It affects your quality of life!

People with dry eye disease may experience irritated, gritty, scratchy, or burning eyes, excess watering, and blurred vision. The level of discomfort is increased if you wear contact lenses or live in a dry climate. Paying attention to dry eye symptoms is important. If left untreated it may become so severe and debilitative that it interferes with work and normal life activities.

Causes of Dry Eye 

There are many causes with several broad categories of dry eye. Each type comes with particular treatments. There is some overlap between the types of dry eye, making the condition challenging to manage.

Evaporative dry eye

Meibomian Gland Dysfunction evaporative dry eye 

Environmental evaporative dry eye  

Life style – staring at computer screens, televisions, or electronic readers for long periods of time, exposure to air conditioning, wind, smoke, and dry climates

Aqueous deficient dry eye

The problem is due to decreased production of the aqueous component of the tears film from the lacrimal glands. Aqueous deficiency usually associated with auto-immune diseases (Sjögren's Syndrome and rheumatoid arthritis). Other medical condition such as diabetes, thyroid problem, and inflammation of eyelids. other causes are LASIK or other laser eye surgeries, where patients can experience dryness temporarily or even permanently due to the severing of the corneal nerves. long-term use of contact lenses  Medical treatments such a radiation or chemotherapy may have side effects which cause permanent damage to the lacrimal glands that produce most of the tears. Certain medications such as antihistamines, nasal decongestants, tranquilizers, certain blood pressure medicines may cause aqueous deficiency, Parkinson's medications, birth control pills, hormone-replacement therapy (HRT) and anti-depressants.

Age – dry eye syndrome often gets worse as we age Gender – women are more likely to develop dry eyes

The tear filmEye Care Services

The tear film is structured with 3 components that work together: a complex mucus component, a watery portion (Aqueous) and a complex oil outer layer (Lipid).

The oil component (Lipid) is important for reducing evaporation of tears and also provides structure to the tear lm. Lipid is produced by the meibomian glands and is injected unto the tears with each blink. Meibomian gland dysfunction (MGD) can create a deficiency in the lipid component of the tears, which leads to the evaporative dry eye.

The watery component produced by the lacrimal glands (aqueous) is also important. A lack of aqueous production can result in another type of dry eye called aqueous deficient dry eye. Aqueous deficient dry eye can be associated with disorders such as rheumatoid arthritis and lupus.

Quality and quantity of the tear filmIMG_0586

To measure the quality and stability of the tear film, the OCULUS Keratograph 5M measures the tear film break up time non-invasively. This test takes less than 30 seconds and does not require touching the eye.

To evaluate the quantity of the tear film, the Keratograph 5M takes a picture of the lower eyelid to measure the tear meniscus height.

Lipid layer

The Keratograph 5M can document a movie of the oily layer of the tear film. A healthy and thick lipid layer is colorful and protects the tears from fast evaporation. If there is not enough lipid, the tear lm becomes unstable, the moisture dissipates quickly and both vision and comfort can be compromised.

Meibographyimage

Located in both upper and lower lids, the meibomian glands produce complex oils that stabilize the tear film and prevent tear evaporation. If the meibomian glands do not function properly dry eye usually occurs. Your doctor can utilize the advanced features of the Keratograph 5M to directly assess the health of your meibomian glands.
