Dry Eyes

Dry eye (often called dry eye disease or dry eye syndrome) is one of the most under-diagnosed ocular diseases, and it is one of the most common reasons why patients go see their eye care professional. Eye Clinic of Austin is a TearLab Accredited Dry Eye Center and utilizes the most advanced technology on the market to diagnose and treat dry eyes, including LipiView® and LipiFlow®. To meet with one of our ophthalmologists about your dry eye symptoms and for recommended treatment, please schedule a dry eye assessment with us.

 

What is Dry Eye?

There are two main forms of dry eye, evaporative dry eye and aqueous deficient dry eye. Many people mistake the dry eye symptoms for allergies, climatic conditions or just eyestrain. While all of these may aggravate dry eye symptoms, they are not the cause.

Evaporative Dry Eye
Evaporative dry eye accounts for 86% of all dry eye cases and occurs when a person’s Meibomian glands are blocked. Meibomian glands are located in the eyelids and this condition of obstructed glands is known as Meibomian Gland Dysfunction (MGD). When functioning properly, the Meibomian glands create a lipid (oil) layer of tears. Without this tear film oil, an individual’s tears can evaporate four to sixteen times faster causing discomfort and dryness, thus the name evaporative dry eye.

Aqueous Deficient Dry Eye
Aqueous deficient dry eye occurs when the lacrimal glands do not produce a sufficient amount of aqueous (water) to keep the eyes moist. In aqueous deficient dry eye, underlying changes to these tear-producing glands result in a lower quantity of tears being made and not enough water reaches the surface of the eye.

Both evaporative dry eye and aqueous deficient dry eye can lead to damage of the eyes’ surface, which, in turn, can lead to the symptoms of dry eye. Reduced tear production over a long period of time increases the risk of permanent damage and scarring to the front of the eye.

 

What Causes Dry Eye?

Dry eye can be caused by multiple different factors including:

Environmental Causes
Changes in environment can cause dry eye such as hot, dry and/or windy climates, high altitudes, excessive sun exposure, central heating, air conditioning, hair dryers, cigarette smoke, air pollution, and air travel.

Medications (prescription or over the counter)
Many medications can cause dry eye. These medications can include allergy medications, especially antihistamines, antidepressants (Amitriptyline, Diazepam), some blood pressure medications, Parkinson’s medications, birth control pills, diuretics, beta blockers, sleeping pills, many pain medications, certain medications which regulate heart rhythm irregularities, and decongestants.

Contact Lens Wear
Wearing contact lenses while sleeping when the lenses are not designed for that type of wear can be a cause of dry eye. In addition, wearing the lenses for a longer period of time than they are designed for can also cause this issue. An example would be wearing 2-week disposable contact lenses for longer than that 2-week period.

Non Eye-Related Diseases
Individuals with Parkinson’s disease, Sjögren’s syndrome (an auto-immune disease), Rheumatoid arthritis, Lupus, Lacrimal gland deficiency, Diabetes, Sarcoidosis, Stevens-Johnson syndrome, or Rosacea can experience dry eye.

Refractive Eye Surgery
After LASIK, some individuals do experience dry eye.

Hormonal Deficiencies or Changes
Thyroid conditions, hormonal changes during menopause, decreased production of androgen, and estrogen supplementation can cause dry eye.

Low blink rate
Blinking is critical in spreading tears over the surface of the eye and stimulating tear production. A chronic low blink rate is associated with dry eye symptoms. Computer use, reading, and watching TV are the three activities most commonly associated with a low blink rate.

 

Dry Eye Symptoms & Diagnosis 

Symptoms of dry eyes may include stinging, burning, scratchy sensation, sensitivity to light, tearing, tired eyes, and difficulty wearing contact lenses. In addition, many patients suffer from blurred vision, often worsening at the end of the day or after visually focusing for a prolonged period on a nearby task.

The first step in dry eye diagnosis is to schedule a dry eye assessment to diagnose the disease. At Eye Clinic of Austin, we use a couple of different devices to diagnosis dry eye and the severity of the disease including the TearLab® Osmolarity test and the LipiView test.

TearLab Osmolarity Testing Device

TearLab Osmolarity Test
The TearLab Osmolarity test is a painless process which tests a tiny tear sample to measure osmolarity (salt content) in the tears. Tear osmolarity has been shown to have one of the best predictive values of any single test for diagnosing dry eye disease. The test provides our eye doctors a meaningful measure of the health and stability of the protective tear film that covers the surface of your eyes.

LipiView Testing Device

LipiView Test
The LipiView device takes extremely detailed images of your eye’s tear film allowing the physician to evaluate the lipid (oil) layer on your eye. This non-invasive test takes less than five minutes and the patient will see their tear film as an array of colors that are reflected when a light source is directed towards the front surface of the eye.

 

Dry Eye Treatment

Eye Clinic of Austin offers many advanced treatments to help patients experience relief from dry eye. Our eye doctors prescribe custom therapies depending on the type of dry eye a patient is experiencing. These therapies may include lubricating the eye with topical artificial tears, a prescription eye drop, or LipiFlow treatment.

LipiFlow Thermal Pulsation System

LipiFlow Treatment
The LipiFlow Thermal Pulsation System by TearScience® is the first and only treatment that addresses the cause of evaporative dry eye: blocked Meibomian glands. For individuals who have tried to alleviate symptoms with eye drops and warm compresses, LipiFlow treatment may be the key for sustained relief from dry eye.

The LipiFlow relieves Meibomian gland blockage by applying a combination of directed heat and pulsation pressure. The LipiFlow Activator (a disposable eyepiece) is inserted under the lower and upper eye lid and is shaped to prevent contact with the cornea. Once in place, the patient simply reclines in the treatment chair for the 12 minute procedure.

Think of it as a “spa treatment” for your eyes. Gentle heat and light pressure create a warm massage that stimulates the Meibomian glands’ natural lipid production and helps restore the balance disrupted by evaporative dry eye. Opening and clearing these blocked glands can allow them to resume natural production of lipids (oils) needed for a healthy tear film. Four weeks after a single LipiFlow procedure, 79% of patients reported an improvement in overall dry eye symptoms.
