What is Dry Eye?

Dry eye is a complex, multifactorial disease process that affects the eye’s ability to produce healthy lubrication for the ocular surface. It is a long-term chronic disease that takes years to develop and may worsen if left untreated.

Dry eye is a complex, multifactorial disease process that affects the eye’s ability to produce healthy lubrication for the ocular surface.
Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. Dry eye is a common and often chronic problem, particularly in older adults.
With each blink of the eyelids, tears spread across the front surface of the eye, known as the cornea. Tears provide lubrication, reduce the risk of eye infection, wash away foreign matter in the eye and keep the surface of the eyes smooth and clear. Excess tears in the eyes flow into small drainage ducts in the inner corners of the eyelids, which drain into the back of the nose.
Dry eyes can occur when tear production and drainage are not in balance. Tears are a mixture of different ingredients, but primarily oil and water. If either ingredient is not present in appropriate amounts, we experience symptoms of dryness.

People with dry eyes either do not produce enough tears or their tears are of poor quality.

Inadequate amount of tears. Tears are produced by several glands in and around the eyelids. Tear production tends to diminish with age or as a side effect of certain medicines. Environmental conditions, such as wind and dry climates, can also decrease tear volume due to increased evaporation. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop.
Poor quality of tears. Tears are made up of three layers: oil, water, and mucus. Each component protects and nourishes the front surface of the eye. A smooth oil layer helps prevent evaporation of the water layer, while the mucin layer spreads the tears evenly over the surface of the eye. If the tears evaporate too quickly or do not spread evenly over the cornea due to deficiencies with any of the three tear layers, dry eye symptoms can develop.

Lipid (oil) layer: lubricates and prevents evaporation.
Aqueous (water) layer: nourishes and protects the cornea
Mucin layer: adheres tears to the eye
Meibomian glands: create the lipid (oily) layer of the tear film, a blockage can lead to evaporative dry eye

What are the symptoms of Dry Eye?

Dry eye is something that is not “cured” with artificial tears. Artificial tears are generally a component of treatment, however, they do not impact the underlying cause of dryness. Dry eye is rarely cured permanently, ongoing management is necessary.

If you suffer from any of these symptoms from time to time, you may benefit from a visit with our specialists at our Dry Eye Clinic.

There are two kinds of Dry Eye?

Evaporative Dry Eye

Evaporative Dry Eye accounts for 86% of all dry eye cases and is caused by blockages in the Meibomian glands located in your eyelids

This condition of obstructed glands is known as Meibomian Gland Dysfunction(MGD). These glands are responsible for creating the lipid (oil) layer of tears. When the glands aren’t working as they should, you don’t have enough tear film oil.
Your tears- which lubricate your eyes and keep them comfortable-evaporate too quickly. An insufficient oil layer can cause your tears to evaporate 4-16 times faster.

Aqueous Deficient Dry Eye

Aqueous Deficient Dry Eye occurs when the lacrimal glands do not create a sufficient amount of aqueous (water) to keep the eyes moist.

How do we determine if you are suffering from Dry Eye?

In our Dry Eye Clinic, we will conduct a series of evaluations and determine the likely causes of your symptoms. LipiView takes extremely detailed images of your eye’s tear film.

The tear film can be clearly seen as an array of colors that are reflected when a light source is directed towards the front surface of the eye. Readings are instantly calculated and displayed on the LipiView monitor.

What causes Dry Eye?

Dry eyes can develop for many reasons, including:

AGE. Dry eyes are a part of the natural aging process. The majority of people over age 65 experience
some symptoms of dry eyes.GENDER. Women are more likely to develop dry eyes due to hormonal changes caused by pregnancy, the use of oral contraceptives and menopause.

MEDICATIONS. Certain medicines, including antihistamines, decongestants, blood pressure medications, and antidepressants, can reduce tear production.

ENVIRONMENTAL CONDITIONS. Exposure to smoke, wind and dry climates can increase tear evaporation resulting in dry eye symptoms. Failure to blink regularly, such as when staring at a  computer screen for long periods of time, can also contribute to drying of the eyes.
OTHER FACTORS. Long-term use of contact lenses can be a factor in the development of dry eyes.
Certain eye surgeries can contribute to dryness.

We have a variety of dry eye treatments available for you here at our Dry Eye Clinic.
