Can Dry Eye Be a Sign of Autoimmune Disease? What a New Case Series Reveals

Most people assume dry eye is just dry eye — annoying, treatable, and not connected to anything bigger. But for a meaningful subset of patients, chronic dry eye that doesn't respond to standard treatment is actually the first visible sign of an underlying autoimmune disease. That's the focus of a case series recently presented at a major national eye care conference by Dr. Shawn Matsumoto, OD, of Resolution Eyecare, alongside clinical assistant Fatima Alvidrez.

This post breaks down what the case series found, why it matters for anyone struggling with treatment-resistant dry eye, and what signs are worth bringing up with your eye doctor.

Quick Answer: Can Dry Eye Be Linked to Autoimmune Disease?

Yes. Conditions like Sjögren's syndrome, rheumatoid arthritis, and systemic lupus erythematosus (SLE) frequently show up first as ocular surface symptoms — dryness, irritation, light sensitivity, and inflammation — sometimes years before a formal diagnosis. A case series presented by Resolution Eyecare's Dr. Shawn Matsumoto found that dry eye patients who didn't respond to standard treatment, including advanced therapies like intense pulsed light (IPL), were ultimately diagnosed with underlying autoimmune conditions after targeted bloodwork and rheumatology referral.

Why This Research Matters

Dry eye disease has become its own clinical specialty, and advancements in over the counter medications is becoming widely available. But that sophistication carries a responsibility: when a patient's dry eye doesn't respond the way it should, the question shouldn't just be "what's the next treatment to try" — it should be "is something else going on."

Diagnostic delays for systemic autoimmune conditions like lupus are a well-documented problem, with research showing delays ranging from roughly 9 to 78 months between symptom onset and diagnosis. Because many of these conditions are treatable and far more manageable when caught early, an eye doctor recognizing the pattern can meaningfully shorten that delay — sometimes being the first provider to catch it at all.

Inside the Case Series: Three Patients, One Pattern

The case series, titled "Dry Eye or Disguise? Recognizing Systemic Autoimmune Disease in an Era of Dry Eye Specialty Care," presented three de-identified patient cases that each followed a similar arc: persistent dry eye symptoms, limited response to standard dry eye treatment, and an eventual autoimmune diagnosis once systemic evaluation was pursued.

Case 1: Refractory Dryness Traced to Sjögren's Syndrome

A 28-year-old patient presented with severe, treatment-resistant dryness, light sensitivity, and episodic pain that didn't improve with artificial tears, low-level light therapy, or IPL. Examination revealed mild inflammation in the front chamber of both eyes, along with recurring eyelid redness and excessive tearing that had previously been attributed to chronic allergic conjunctivitis. Bloodwork showed elevated rheumatoid factor and a positive ANA (antinuclear antibody) result, along with dry skin rashes on the extremities. The patient was diagnosed with and is now co-managed for Sjögren's syndrome, with ongoing monitoring alongside rheumatology.

Case 2: Dry Eye and Episcleritis Leading to a Rheumatoid Arthritis Diagnosis

A second 28-year-old patient, previously diagnosed with dry eye and episcleritis (inflammation of the eye's outer layer), returned with recurring light sensitivity and tearing despite an initial response to a prescription steroid eye drop. Examination showed significant inflammation inside the eye in both eyes. Bloodwork revealed a high rheumatoid factor and elevated ANA titer. Rheumatology diagnosed inflammatory polyarthropathy with high suspicion for rheumatoid arthritis, and the patient's eye inflammation was managed with a tapering steroid protocol, eventually stabilizing on a low-dose maintenance regimen.

Case 3: Longstanding Dryness Revealed as Systemic Lupus Erythematosus

A 36-year-old patient with long-term, treatment-resistant dryness and a first-degree family history of Sjögren's syndrome had never undergone systemic bloodwork despite a prior dry eye diagnosis. Testing revealed a positive ANA, an elevated titer, and a positive anti-dsDNA antibody result — findings consistent with systemic lupus erythematosus (SLE). The patient was started on hydroxychloroquine by rheumatology, with baseline eye imaging obtained to monitor for medication-related effects, and a more targeted dry eye treatment plan put in place alongside quarterly follow-up.

The Common Thread

Across all three cases, the same gap appeared: until they came to us, systemic disease was never considered as a possible cause of the dry eye symptoms, and treatment continued without any broader diagnostic workup. It wasn't until bloodwork and rheumatology referral were pursued that the underlying cause became clear.

This pattern connects to an emerging concept in eye care research called dry eye with autoimmune features (DEAF) — the idea that a meaningful subset of dry eye patients are living with undiagnosed autoimmune disease that will continue to progress if it isn't identified.

What This Means If You Have Treatment-Resistant Dry Eye

If you've been treating dry eye for months or years without meaningful improvement, it may be worth discussing the possibility of an underlying systemic cause with your eye doctor — particularly if you also notice:

• Joint pain or stiffness

• Unexplained fatigue

• Dry mouth alongside dry eyes

• Skin rashes, especially on sun-exposed areas

• A family history of autoimmune disease

• Recurring inflammation inside the eye (not just on the surface)

None of these symptoms automatically mean you have an autoimmune condition — but together, they're a reason to ask whether bloodwork and a broader evaluation make sense.

Why This Shapes How Resolution Eyecare Approaches Dry Eye

This research reflects a core principle behind how dry eye disease is managed at Resolution Eyecare: dry eye specialty care shouldn't be only about offering more advanced treatments — it should also mean recognizing when a patient isn't responding the way they should, and asking why. For patients with unresolved symptoms, that can mean targeted bloodwork and coordinated referral to rheumatology, not just another round of in-office treatment.

About Resolution Eyecare

Resolution Eyecare is a locally owned, award-winning optometry practice with studios in Highland, Tech Ridge, and Round Rock, serving Austin, Round Rock, Georgetown, Brushy Creek, and Hutto. Dry eye disease management is one of the practice's core clinical specialties, led by Dr. Shawn Matsumoto, whose research on dry eye and systemic autoimmune disease was presented at a major national eye care conference. Alongside Dr. Justine Hung, the two make up the practice's clinical team, with additional focus on comprehensive eye care, myopia management, specialty contact lenses, and emergency eye care.

Frequently Asked Questions

Can dry eye really be an early sign of autoimmune disease? Yes. Conditions like Sjögren's syndrome, rheumatoid arthritis, and lupus often present first with ocular surface symptoms, sometimes well before a formal diagnosis is made elsewhere.

When should I be concerned that my dry eye isn't "just" dry eye? If standard treatments — artificial tears and prescription drops — haven't meaningfully improved your symptoms, especially alongside joint pain, fatigue, dry mouth, or skin changes, it's worth discussing a broader evaluation with your eye doctor.

What is "dry eye with autoimmune features" (DEAF)? It's an emerging concept in eye care research describing a subset of dry eye patients whose symptoms are driven by an underlying, often undiagnosed, autoimmune condition rather than standard tear film dysfunction alone.

Does having one of these risk factors mean I have an autoimmune disease? No. These are signs worth discussing with your doctor, not a diagnosis on their own. A proper evaluation, including bloodwork, is needed to determine the actual cause of persistent symptoms.

If Your Dry Eye Isn't Improving, It's Worth a Closer Look

Persistent dry eye that isn't responding to treatment deserves more than another prescription — it deserves a second look at what might actually be causing it.
