Dry eyes are a hallmark symptom of Sjögren's disease, an autoimmune disease that affects the body’s moisture-producing glands.
For those living with this condition, understanding why dry eyes occur and how Sjögren’s impacts the eyes’ natural tear system is key to managing symptoms and finding effective relief.
In this post, we’ll explore the relationship between Sjögren's disease and dry eyes, break down the composition of the tear film, and explain how Sjögren’s impacts tear quality and production.
How Dry Eyes Relate to Sjogren's Disease
Sjögren's disease primarily targets the glands responsible for producing moisture in the body, including the lacrimal glands (responsible for tears).
This immune attack reduces tear production and disrupts the delicate balance of the tear film, leading to chronic dryness, irritation, and discomfort.
Without adequate lubrication, the eyes can feel gritty, itchy, and even painful.
Over time, untreated dryness can result in damage to the corneal surface and increase the risk of infections. Understanding how Sjögren’s impacts the tear film can help you take proactive steps to protect your eyes.
The Composition of Tears
The tear film is a complex, multi-layered structure that works to hydrate, nourish, and protect the eyes. It consists of three main layers:
Mucus Layer
The innermost layer that helps tears adhere to the surface of the eye.
Produced by goblet cells in the conjunctiva, it ensures the even distribution of tears.
Aqueous Layer
The middle layer, primarily made of water, provides hydration and nutrients to the eye.
Secreted by the lacrimal glands, it also contains antibacterial proteins to fight infections.
Lipid Layer
The outermost layer, composed of oils, prevents evaporation and stabilizes the tear film.
Produced by the meibomian glands along the eyelid margins.
A healthy tear film requires all three layers to function in harmony. When one layer is disrupted, it affects the entire system.
How Sjogren's Impacts Tear Quality (Lacrimal Gland)
The lacrimal glands are responsible for producing the aqueous layer of the tear film.
In Sjögren's disease, these glands are often the primary target of the immune system, leading to inflammation and reduced tear production.
With a diminished aqueous layer:
The eyes receive less hydration, resulting in dryness and irritation.
The tear film becomes unstable, increasing the risk of damage to the corneal surface.
The protective antibacterial proteins in tears are also reduced, heightening infection risk.
How Sjogren's Impacts the Lipid Oil Layer (Meibomian Gland)
The meibomian glands, located along the edges of the eyelids, produce the lipid (oil) layer of the tear film. This layer prevents the aqueous layer from evaporating too quickly and stabilizes the overall tear film.
In Sjögren's disease:
Chronic inflammation can affect the meibomian glands, reducing oil production.
Without enough oil, the tear film evaporates faster, exacerbating dryness.
This imbalance often leads to meibomian gland dysfunction (MGD), which is common in Sjögren's patients.
Blepharitis, chronic inflammation of the eye lids is also common in Sjogren's patients.
Addressing the lipid layer is as important as restoring moisture to provide comprehensive relief for dry eyes.
How to Manage Dry Eyes
Managing dry eyes caused by Sjögren's disease often requires a combination of targeted treatments and supportive therapies.
For lacrimal gland dysfunction, which leads to reduced tear production, moist heat eye masks can stimulate blood flow and improve tear quality.
These masks also provide relief for meibomian gland dysfunction (MGD), a common issue in Sjögren’s patients, by melting clogged oils and restoring the lipid layer of the tear film.
Additionally, eyelid wipes can help manage blepharitis by keeping the eyelid margins clean and reducing inflammation.
For daily supplementation, artificial tears or preservative-free eye drops can provide much-needed hydration, acting as a replacement for natural tear production. By combining these therapies, you can address both the causes and symptoms of dry eyes for better long-term comfort and eye health.
Take Control of Dry Eyes
Dry eyes in Sjögren's disease is complex, but understanding how the condition affects your tear film is the first step toward effective management.
By targeting both tear production and tear quality, you can alleviate discomfort and protect your eyes from further damage.
