Sjögren’s Syndrome and Dry Eye
What is Sjögren’s Syndrome?
Sjögren’s syndrome is a condition where the body's immune system mistakenly attacks its own moisture-producing glands. This primarily affects tear and saliva glands but can also involve other organs and tissues, leading to systemic symptoms.
Sjögren’s syndrome is an autoimmune disorder in which the body’s defense system targets and damages glands responsible for producing tears and saliva. This immune attack results in significant dryness of the eyes and mouth, as well as potential involvement of other organ systems.
This syndrome can occur in people of any age but is far more common in women, affecting them about nine times as often as men. It most predominantly affects those over 40 years old, and it is estimated that approximately 4 million adults in the United States have Sjögren’s syndrome.
There are two main types of Sjögren’s syndrome, which are classified based on whether another autoimmune condition is present.
- Primary Sjögren’s: This type occurs by itself, without the presence of another autoimmune disease.
- Secondary Sjögren’s: This type occurs alongside other autoimmune diseases, such as rheumatoid arthritis or lupus.
Causes of Dry Eye in Sjögren’s Syndrome
In Sjögren’s syndrome, dry eye results from inflammation and damage to the tear-producing glands, which disrupts the eye's natural lubrication system. This leads to a reduction in both the quantity and quality of tears.
The immune system produces antibodies that attack the lacrimal glands responsible for tear production. This autoimmune reaction causes inflammation and gland damage, leading to a significant reduction in tear volume and contributing to severe dry eye symptoms.
The inflammation can extend to the ocular surface, which includes the cornea and conjunctiva. This causes soreness, redness, and heightened sensitivity to light, worsening eye discomfort and potentially causing surface damage if left untreated.
A healthy tear film has three layers: a watery aqueous layer, an oily lipid layer, and a mucus-like mucin layer. In Sjögren’s syndrome, the oil-producing meibomian glands are often dysfunctional, causing the lipid layer to thin. This leads to tears evaporating too quickly and impairs their ability to lubricate and protect the eye surface.
Symptoms of Dry Eye
Dry eye symptoms can range from mild to severe and often interfere with daily activities, causing significant distress and reducing overall quality of life. Recognizing these symptoms is the first step toward getting effective treatment.
People with Sjögren’s-related dry eye commonly experience one or more of the following signs:
- A dry, scratchy, or gritty sensation
- Burning or stinging feelings in the eyes
- Redness or irritation
- Blurred or fluctuating vision that may improve with blinking
- Sensitivity to light, also known as photophobia
- Excessive tearing, which is a reflex response to the irritation
- Eye fatigue, especially when reading or using digital screens
Chronic dry eye can make everyday tasks like reading, driving, and working on computers very uncomfortable. Patients often need to blink frequently or take breaks to avoid eye strain, and ocular discomfort can even affect sleep quality.
How Dry Eye is Diagnosed
The diagnosis of dry eye related to Sjögren’s syndrome involves a thorough clinical evaluation. This includes a review of your symptoms, specialized eye tests, and laboratory studies to confirm an autoimmune cause.
Your eye doctor will ask about your symptoms, other medical conditions like dry mouth, and any medications you take. A history of systemic autoimmune diseases can help point to Sjögren’s syndrome as the underlying cause of your dry eye.
Tests like the Schirmer test are used to measure tear quantity. This test involves placing a small strip of filter paper under the lower eyelid for a few minutes to determine if tear production is abnormally low.
This test measures the stability of your tear film. A special dye is applied to the eye, and your doctor observes how quickly dry spots form on the surface. A short break-up time indicates that your tears are evaporating too quickly.
Dyes such as fluorescein or lissamine green are used to highlight any dry or damaged spots on the cornea and conjunctiva. This allows your doctor to see the extent and pattern of damage caused by chronic dryness.
Blood tests can check for specific autoantibodies, such as anti-Ro/SSA and anti-La/SSB, which are commonly present in patients with Sjögren’s syndrome. These tests help confirm the diagnosis and guide systemic management.
Treatment Options
The treatment for dry eye in Sjögren’s syndrome is multifaceted, aiming to restore moisture, reduce inflammation, and protect the ocular surface. A personalized plan may combine several different approaches to improve comfort.
Over-the-counter artificial tears and lubricating gels provide temporary relief by supplementing natural tears. Preservative-free formulas are highly recommended for frequent use to avoid the additional irritation that preservatives can cause.
Prescription eye drops such as cyclosporine or lifitegrast are designed to target underlying inflammation, which can help your body increase its natural tear production over time. Corticosteroid drops may also be used for short-term management of flare-ups.
Punctal plugs are tiny, biocompatible devices inserted into the tear ducts in the corners of the eyelids. These plugs block tear drainage, helping to keep both natural tears and artificial tears on the eye surface for a longer period.
For severe cases, scleral lenses can provide significant relief. These are large-diameter gas permeable lenses that vault over the cornea and rest on the white part of the eye, creating a fluid-filled reservoir that continuously bathes the eye in moisture.
Specialized glasses or goggles create a humid environment around the eyes. This reduces tear evaporation and protects the eyes from harsh environmental factors like wind, dust, and dry air, which can provide substantial relief.
Simple adjustments at home and work can ease dry eye symptoms. These modifications can have a significant impact on your daily comfort.
- Take regular breaks from screens using the 20-20-20 rule.
- Use a humidifier to add moisture to dry indoor air.
- Wear wraparound sunglasses outdoors to shield your eyes.
- Apply warm compresses to your eyelids to improve oil gland function.
- Stay well-hydrated by drinking plenty of water.
When dry eye is part of widespread Sjögren’s syndrome activity, a rheumatologist may recommend systemic medications. Drugs like hydroxychloroquine or methotrexate can be used to reduce the body's overall inflammation.
In very severe and refractory cases, surgical procedures may be considered. These can include a partial eyelid closure, known as a tarsorrhaphy, to reduce tear evaporation, or the application of an amniotic membrane graft to protect and heal the ocular surface.
Frequently Asked Questions
Here are answers to some of the most common questions about dry eye in Sjögren’s syndrome to help you better understand and manage your condition.
There is currently no cure for Sjögren’s syndrome. However, with proper treatment and consistent management, symptoms can be controlled effectively, improving both comfort and quality of life.
Most artificial tears are safe, especially preservative-free options. Some people may experience mild, temporary blurriness or slight irritation immediately after application, but these effects usually resolve quickly.
Without treatment, dry eye symptoms can progress and may lead to more severe discomfort and potential damage to the eye's surface. Consistent care and regular follow-ups with your eye doctor help prevent progression.
A diet rich in omega-3 fatty acids, found in fish and flaxseed, may help improve tear quality and reduce inflammation. It is important to talk with your healthcare provider before starting any new supplements.
Yes, it can lead to complications such as inflammation of the cornea (keratitis) or conjunctiva (conjunctivitis), and can increase the risk of eye infections and scarring if the dryness is not properly managed.
If you have Sjögren’s syndrome, regular eye exams every 6 to 12 months are recommended. More frequent visits may be necessary if your symptoms worsen or if complications develop, allowing for timely adjustments to your treatment plan.
Yes, hormonal changes, particularly those occurring during menopause or pregnancy, can worsen dry eye symptoms by affecting tear production. Your treatment plan may need to be adjusted during these times.
Some eye makeup products, especially those with fragrances or preservatives, can clog oil glands and irritate sensitive, dry eyes. Using hypoallergenic, fragrance-free products and ensuring thorough makeup removal can help minimize irritation.
