Eye-deology Vision Care: Edmonton Optometrists, Opticians and Eyewear

Dry Eye Treatment For Discomfort and Infections.

Dry eyes occur when the eyes do not produce sufficient tears or when tears evaporate too quickly. Approximately 30% of Canadians experience ocular symptoms associated with dry eye. These symptoms include stinging or burning eyes, scratchiness, pain, or redness. Oddly, one symptom of dry eye can be excessive tear production, which results in tears rolling down their face. Our optometrists are uniquely skilled and equipped with the technologies to diagnose and treat dry eyes.

A thin film of liquid covers the surface of the eye. This thin film, called the tearfilm, provides lubrication to the exterior part of the eye and facilitates blinking. As the eye surface begins to dry, dry spots can develop within the tear film and expose the nerves of the cornea to the motion of the eyelid during blinking, resulting in an irritating sensation. Throughout the day, the average person blinks more than 11,500 times. For people with dry eyes, each blink can irritate and can even painful.

  • Environment. Dry, over-heated, over-cooled, or smoky air.
  • Medications. Many medications (e.g., antihistamines, decongestants, antidepressants) result in dry eyes.
  • Ageing. Individuals produce fewer tears as they age.
  • Systemic Disorders. Many autoimmune diseases result in dry eye symptoms.
  • Skin Inflamation. Rosacea and blepharitis.
  • Computer Vision Syndrom. The tendency to blink less when looking at screens.
  • Laser Eye Surgery. Surgery can affect blinking and tear film production.
  • Gender. Dry eye symptoms are more prevalent amongst females.
  • Contact Lenses. Contact lens wear increases the likelihood of dry eyes.

Tears play an essential role in keeping us healthy. Tears keep the surface of our eyeballs clean and moist and help protect our eyes from damage. Although they may appear to be nothing more than water, our tears are quite complex. Tears are a combination of mucus, water, and oil, and each component plays a role in the eye.

  • Mucus. Mucus coats the surface of the eye and helps bind the tear layer to the eye. Without a healthy mucus layer, dry spots may form on the cornea, the clear, dome-like structure on the front of the eye.
  • Water (Aqueous). The water is more of a saline (salt) solution that contains various vitamins and minerals vital to normal cell function. These nutrients are essential for keeping the top layer of cells on the eye surface, the epithelium, healthy and functioning normally.
  • Oil (Lipid). The oil of the tear film prevents evaporation of the tears. Some people don't make enough oil (or sometimes too much oil), resulting in dry eyes. If the oil component is not satisfactory, the tears evaporate too quickly.

During a comprehensive eye exam, our optometrists would discover your dry eye symptoms. There are several traditional tests that can be used to assess your dry eye. These include the use of a paper strip that measures the volume of tears produced, the application of fluorescent dye to the surface of the eye to assess whether dry spots are present or how quickly they appear following blinking.

These traditional tests are useful, but are qualitative in nature and can sometimes make patients uncomfortable. That is the reason why eye-deology Vision Care invested in modern technologies that enable our optometrist to non-invasively and quantitatively diagnose dry severity and cause(s).

Dry Eyes: Assessing Tear Osmolarity

eye-deology Vision Care optometrists use a corneal topographer and keratographer that enables them to examine to determine the cause of dry eye symptoms:

  • Meibomian Glands. he dysfunction of meibomian glands is the most frequent cause of dry eye. Morphological changes in the gland tissue are made visible and can be classified.
  • Non-Invasive Tear Film Break-Up Time. A non-invasive scan that measures and maps tear film breakup across the surface of the eye.
  • Tear Meniscus Height. Precise tear meniscus height measurements along the edge of the bottom lid to assess tear production and tear film quality.
  • Tear Film Dynamics. An observation of the tear film particle flow to determine tear film viscosity.
  • Lip Layer Amount & Health. The interference colours of the lipid layer and their structure are made visible and recorded. The thickness of the lipid layer is assessed based on the composition and colour.
  • Redness. Evaluation of the bulbar and limbal degree of redness. The R-Scan detects the blood vessels in the conjunctiva and evaluates the degree of redness.

Dry eye is usually chronic, and it has no cure. However, artificial tears and treatment can assist in maintaining comfort and eye health. For more severe dry eye, gels and ointments can be used, especially at bedtime. Your doctor of optometry is the best source to advise on the best drops and treatment for you. In some cases, small plugs are inserted in the corner of the eyelids to slow drainage and loss of tears. Treating an underlying systemic disease or changing the diet to include items such as fish or flaxseed oil can also be helpful at times. New prescription medications are now available to help your body produce more tears. There is a wide range of treatments available for the control of Dry Eye symptoms. Not all treatments work for all people. You may need to try more than one before finding a treatment that works for you.
