Understanding Dry Eye Syndrome: Causes Like Aging, Medications, and Autoimmune Disease
Share
Introduction
Dry eye syndrome is a common condition affecting millions of people. Its key symptoms include irritation, redness, blurred vision, and a gritty sensation. While temporary dryness can affect anyone, chronic dry eye tends to have multiple underlying causes that are important to understand.
What Leads to Chronic Dry Eye Syndrome?
Research suggests that dry eye syndrome often results from issues with the quality or quantity of tears coating the surface of the eyes. Tears help lubricate, nourish, and protect the eyes. When tear composition and production are disrupted, dry areas can develop on the eyes and cause discomfort.
Common culprits behind dry eye include:
- Age-related changes
- Medications
- Autoimmune disorders
Let's explore the role each of these factors play.
Aging Changes Like Decreased Tear Production
As we age, our bodies go through changes that can reduce tear quantity and quality. For example, the glands responsible for making the lipid layer of tears tend to atrophy and function less optimally. The lipid layer prevents quick evaporation of tears. With gland dysfunction, the tear film loses stability and eyes grow dry faster.
Additionally, around age 60, our lacrimal glands make fewer tears overall. With less fluid available to keep eyes lubricated all day, dry spots appear more readily.
Medications: Antihistamines, Diuretics and More
Many common medications have anticholinergic effects, meaning they block acetylcholine - a nervous system messenger needed for tear secretion. Without enough acetylcholine reaching the lacrimal glands, tear production slows.
Notable drugs linked to dry eye as a side effect include:
- Antihistamines
- Blood pressure medications
- Antidepressants
- Tranquilizers
- Diuretics
- Birth control pills
- Accutane
Always read drug labels for information on ocular side effects and consider speaking to your pharmacist. Your provider may also recommend lower-risk alternatives to preserve eye health if you develop dryness and irritation.
Autoimmune Conditions Like Sjögren's Syndrome
Autoimmune disorders like rheumatoid arthritis, lupus, and Sjögren's syndrome are strongly tied to dry eye. With these conditions, the immune system attacks and damages tear-producing glands, impairing their function. Tear quantity and quality decline over time as a result.
Managing the immune factors involved aims to preserve tears and comfort. But treatments specifically targeting dry eye also help provide relief.
Lifestyle Tips and Treatments
While we cannot stop the clock on aging or cure autoimmune disease, certain lifestyle measures can help ease dry eye discomfort:
- Blinking more frequently when using
screens
- Ensuring air moisture levels at home are sufficient
- Adjusting medications at your doctor's discretion
- Applying warm compresses to unclog meibomian glands
- Using ocular lubricants to supplement natural tears
Prescription anti-inflammatory eye drops also reduce immune reactions on ocular surfaces in some cases.
Summary
Dry eye syndrome has a wide range of potential causes, including aging changes, medications that suppress tear formation, and autoimmune conditions affecting lacrimal gland health. Reduced quantity and quality of tears allows dry spots to develop on the eyes. Staying informed about contributing factors allows you to pinpoint relevant lifestyle tips and treatments to manage irritation. But always see your eye doctor for personalized care recommendations.
