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 lm is important for keeping the eye moist and comfortable. 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 syndrome 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 that it interferes with work and normal life activities.
Life style – staring at computer screens, televisions, or electronic readers for long periods of time, exposure to air conditioning, wind, smoke, and dry climates
Age – dry eye syndrome often gets worse as we age Gender – women are more likely to develop dry eyes
Other factors – long term use of contact lenses, refractive eye surgery, some medications, medical conditions, such as, rheumatoid arthritis, diabetes, thyroid problems and inflammation of the eyelids.
The tear film
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 de ciency in the lipid component of the tears, which leads to 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 de cient dry eye. Aqueous de cient dry eye can be associated with disorders such as rheumatoid arthritis and lupus.
The Keratograph 5M examination
At Empress Eye Clinic your eye doctor is using an advanced technology called the OCULUS Keratograph 5M to examine your eyes. The Keratograph 5M has a high-resolution color camera and is equipped with intelligent software to analyze the collected data and document the findings. It can also compare the results and show the success of the dry eye treatment.
Quality and quantity of the tear film
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.
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.
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.
Dry eye treatments
For evaluating the dry eye and ocular surface disease and measuring the quality and quantity of the tear film, optometrists at Empress Eye Clinic in North York, use an advanced non-invasive diagnostic instrument to create a personalized plan for treatment.
There has been a veritable explosion in understanding the causes of dry eye. A variety of options are now available to help people who suffer from dry eyes. Current approaches include advanced artificial tear eye drop formulations, prescription eye drops that increase tear production and reduce inflammation, and new
approaches to effectively treat meibomian gland dysfunction, which is now understood to play a primary role in most dry eye cases.
Dry eye treatment can now be targeted to address the underlying cause of the problem. Some patients suffer from a lack of tear production, others from excessive evaporation of their tears. Most suffer from a combination of both problems. After a comprehensive examination using the advanced diagnostic tools provided by the Keratograph 5M, your doctor can more accurately assess the precise cause and severity of your dry eye. Using this detailed information, they can recommend the best course of treatment to address your specific problem.
Keratograph® 5M has a high-resolution colour camera and is equipped with intelligent software to analyze the collected data and document the findings. It can also compare the results and show the success of the dry eye treatment.
