Dry Eye Treatment in Portland OR
Dry eye is a common condition that occurs when the eyes are insufficiently moisturized, leading to itching, redness and pain from dry spots on the surface of the eye. The eyes may become dry and irritated because the tear ducts don’t produce enough tears, or because the tears themselves have a chemical imbalance.
Patients with this condition often experience irritating symptoms and can suffer from more serious vision damage if this condition is left untreated. It is important for patients with this condition to take special care of their eyes in order to alleviate symptoms and prevent complications. Your doctor can diagnose dry eye after a thorough evaluation of your eye and tear production through a Schirmer tear test.
Causes of Dry Eye
People usually begin experiencing dry eye symptoms as they age, but the condition can also result from certain medications, conditions or injuries. Dry eye tends to affect women more often than men, as the hormonal changes that take place during pregnancy, menopause and with the effects of oral contraceptives can affect the consistency of tears. It is also more common in people over the age of 50. Other causes may include:
- Medications such as antihistamines, decongestants, blood pressure medications and antidepressants
- Conditions such as rheumatoid arthritis, diabetes and thyroid problems
- Environmental conditions such as smoke, wind and dry climates
- Long-term contact lens use
- Refractive surgery
These factors can affect the frequency or consistency of tears, both of which can lead to dry eyes. Our natural tears require a certain chemical balance in order to efficiently moisturize the eyes.
Treatment for dry eye depends on the cause and severity of the condition, as well as the patient’s overall health and personal preference. Non-surgical treatments are often effective, and may include blinking exercises, increasing humidity at home or work, and use of artificial tears or moisturizing ointment. Prescription eye drops are also available to increase tear production.
If these methods fail, small punctal plugs may be inserted in the corners of the eyes to limit tear drainage, or the drainage tubes in the eyes may be surgically closed. Eyelid surgery is also a solution if an eyelid condition is causing your dry eyes. Treating the underlying cause of dry eyes can also help relieve the symptoms of this condition.
