Dry Eye/MGD Treatment

Dry Eye/MGD Treatment

Dry eye is a condition in which there are insufficient tears to lubricate and nourish the eye or when the essential oils to protect our tear film are not being produced properly. People with dry eyes may experience symptoms of irritated, gritty, scratchy, or burning eyes, a feeling of something in their eyes, excess watering, and blurred vision. Advanced dry eyes may damage the front surface of the eye and impair vision. Dry eye most commonly results from one of the following:

Inadequate amount of tears —Tears are produced by several glands in and around the eyelids. Tear production tends to diminish with age, with various medical conditions, or as a side effect of certain medicines. Environmental conditions such as wind and dry climates can also affect tear volume by increasing tear evaporation. When the normal amount of tear production decreases or tears evaporate too quickly from the eyes, symptoms of dry eye can develop.

Inadequate oil production — The tear film is made up of three layers: oil, water, and mucus. Each component serves a function in protecting and nourishing the front surface of the eye. A smooth oil layer helps to prevent evaporation of the water layer, while the mucin layer functions in spreading the tears evenly over the surface of the eye. If the glands producing the oils do not function properly, the water layer evaporates too quickly and leaves the eye exposed, thus causing dry eye symptoms.

86% of Patients with Dry Eye Have MGD. It's Treatable.

When the meibomian glands, the tiny glands located in the eyelids, do not sufficiently produce and release the oils needed for protecting and ensuring a healthy tear film, this is known as MGD. Often over time, due to a lack of blinking or general debris in the eye, these glands become blocked and stop producing the needed oil to protect the watery layer of the tear film. speedTest Early diagnosis is essential because if left untreated, the glands will deteriorate over time and there is no way to recover from gland loss.

MGD can occur at any age but is more prevalent in adults over 40. The increase of MGD is largely due to the common use of digital display devices today as we are teaching ourselves to blink less creating “evaporative stress”. Over time, the oil in the glands thickens, creating blockages of the gland opening and often oil production ceases.

Treating MGD

Treatment for MGD may include various methods but the most effective is the FDA cleared LipiFlow treatment. LipiFlow uses thermal heat pulsation that essentially “melts” gland blockages and a light massaging action to remove those blockages.

Inadequate tear production?

It was thought for years that dry eye was predominantly caused by a lack of tear production but we now know that MGD is the most prevalent cause of dry eye. Many patients, however, do suffer from keratoconjunctivitis sicca (KCS), also referred to as dry eye syndrome as a direct result of inadequate or impaired tear production

Treating inadequate tear production

In these cases, treatments can range from tiny plugs placed in the corner of the eye to aid in the healthy tear production to prescription medication. Many patients find temporary relief from over-the-counter artificial tear solutions. There are also various self-treatment options such as warm compresses, nutritional supplements, and lifestyle or environmental changes. These treatments aim to restore or maintain the normal amount of tears in the eye, minimize dryness and related discomfort to maintain eye health.

What causes dry eyes?

Age—dry eye is 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. Keep in mind, however, MGD is common among all genders.

Medications—certain medicines, including antihistamines, decongestants, blood pressure medications and antidepressants, can reduce the amount of tears produced in the eyes

Medical conditions—persons with rheumatoid arthritis, diabetes and thyroid problems are more likely to have symptoms of dry eyes. Also, problems with inflammation of the eyelids (blepharitis), inflammation of the surfaces of the eye, or the inward or outward turning of eyelids can cause dry eyes to develop.

Eyelid hygiene – Often debris from the eyelashes and the lid margins are the culprit of contributing to MGD. Lid hygiene is key to maintaining health of the meibomian glands and surface of the eye so both the lashes and lid margins should be cleaned regularly.

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. Refractive eye surgeries, such as LASIK, can cause decreased tear production and dry eyes.

How is dry eye and MGD diagnosed?

Dry eye and MGD can be diagnosed through a comprehensive eye examination. Testing, with special emphasis on the evaluation of the quantity and quality of tears produced by the eyes and proper gland function may include:

  • Patient history
  • External examination of the eye, including lid structure and blink dynamics
  • Evaluation of the eyelids and cornea using bright light and magnification
  • Measurement of the quantity and quality of tears for any abnormalities
  • Dynamic Meibomian Imaging to assess the health of the meibomian glands
  • Tear testing to look for high salt content (hyperosmolarity) or inflammatory markers on the surface of the eye
