Dry Eye: Causes and Treatment

Written by Shannon Wong on December 28, 2020

Dry Eye Treatment in Austin, TXDry eye, also known as dry eye syndrome or keratoconjunctivitis sicca, is a chronic condition that can affect your enjoyment of many of life’s pleasures. Reading, driving, watching a movie or wearing contact lenses may all become a struggle as you blink and rub your eyes throughout the day. Here, the experienced ophthalmologists of Austin Eye review causes and treatment options for dry eye. 

Protective Tears

Your tears do more than show emotion. The fine layer of moisture on the surface of your eye protects sensitive tissues, lubricates eye movement and promotes clarity of vision. Tears are comprised of water, oil and mucus, and a deficiency in any of these can lead to dry eye.

That is why sufferers may, paradoxically, experience watery eyes when they have dry eye syndrome. The oils or lipids secreted by the meibomian glands keep tears from evaporating quickly. When the function of these glands is interrupted, the result is evaporative dry eye. Because the watery surface is constantly dissipating, your eye may increase tear production in response.

Causes

Dry eye syndrome can be triggered by a range of environmental causes, including excessive staring at digital screens, air pollution, windy or dry climate, air conditioning, indoor heating and secondhand smoke.

The chance of developing dry eye increases with age; after menopause, women are more likely to experience dry eye. The condition can also be caused by blood pressure medications, birth control pills and certain diseases.

Symptoms

Symptoms may include pain or a burning sensation in the eyes, itchiness, redness, light sensitivity and blurred vision. Patients may have a feeling that there is a small particle in the eye. This feeling of grittiness or sandiness is usually caused by dry spots, although corneal injuries can also generate the sensation. Both causes are sometimes related: Severe dry eye can cause perforation of the cornea, known as ulceration desiccation of the corneal epithelium. For contact lens wearers, excessive dry eye can also increase the chance of infection.

Treatment

Fortunately, there are many treatments available to those who suffer from dry eye. After evaluating your eyes, your Austin Eye vision care professional will prescribe special eye drops, ointments or gels to keep the surface of your eye lubricated.

If the condition persists, other solutions include topical steroids, protective eyewear, punctal plugs, and eyelid therapy. Punctal plugs are used to block the pathways that drain tears from your eyes. Eyelid therapy focuses on restoring normal operation of the meibomian glands, ensuring sufficient oils are being produced to lubricate the eye and suppress tear evaporation.
