Lyme Disease and Vision Problems: A Case of Optic Neuritis
Vision loss over weeks
Not always a primary eye problem
Lyme disease can be a cause
Early recognition matters
Lyme disease and vision problems can present in unexpected ways—including optic neuritis and significant vision loss.
In this Inside Lyme case, a 46-year-old woman developed rapidly worsening visual symptoms that were ultimately linked to Lyme disease. :contentReference[oaicite:0]{index=0}
A 46-Year-Old Woman With Progressive Vision Loss
The patient developed blurred vision that worsened over three weeks.
Her symptoms extended beyond vision and included:
- Tingling and numbness in both legs
- Nausea
- Weakness
- Dizziness
- Visual hallucinations
A key pattern is multisystem involvement. Vision changes were not isolated—they were part of a broader neurologic picture.
Despite an optometrist identifying optic nerve swelling and recommending emergency evaluation, the patient delayed care.
Optic Neuritis and Severe Vision Impairment
An ophthalmologic exam confirmed optic neuritis, an inflammation of the optic nerve.
Her vision loss was severe:
- Visual acuity: 20/400 in both eyes
- Impaired color vision
For context, legal blindness is defined as 20/200 or worse—highlighting the seriousness of her presentation.
Lyme Disease as the Underlying Cause
Testing supported Lyme disease:
- Positive IgM antibodies
- Positive IgG/IgM serology
- Western blot with partial IgG band positivity
Although CDC surveillance criteria were not fully met, the clinical picture supported the diagnosis.
A key pattern is clinical diagnosis. Lyme disease may still be present even when testing does not meet strict criteria.
The authors concluded there was strong evidence linking Lyme disease to her optic neuritis.
Treatment—and an Uncertain Outcome
The patient was started on doxycycline.
She reported early improvement in vision after beginning antibiotics.
However, the case highlights a critical issue:
- Hospital admission interrupted treatment
- She left against medical advice
- Follow-up was not completed
The final outcome remains unknown.
A key pattern is disruption of care. Incomplete treatment and follow-up can limit recovery—even when diagnosis is correct.
What This Case Teaches
This case reinforces several important clinical points:
- Lyme disease should be considered in optic neuritis
- Vision symptoms may be part of a broader neurologic illness
- Testing may not meet strict criteria despite true infection
- Early treatment may improve outcomes

Unanswered Questions
This case also raises important questions:
- How often does Lyme disease cause optic neuritis?
- What is the best treatment approach?
- What outcomes can be expected with early vs delayed care?
Further research is needed to better define the relationship between Lyme disease and vision problems.
Clinical Takeaway
Lyme disease and vision problems can include serious conditions such as optic neuritis.
When vision loss is accompanied by neurologic symptoms—especially in patients with possible tick exposure—Lyme disease should be part of the differential diagnosis.
Early recognition and consistent follow-up may make the difference between recovery and permanent impairment.
