Neuro-ocular Lyme borreliosis.
Smith, J L · Neurologic clinics · 1991
Quick Summary
This study suggests that some patients diagnosed with chronic fatigue syndrome (CFS) might actually have Lyme disease, a tick-borne infection that can affect the brain and eyes. The authors recommend doctors ask CFS patients detailed questions about tick exposure and check for specific eye and neurological problems, then use blood and urine tests to look for evidence of Lyme infection.
Why It Matters
For ME/CFS patients, this work is significant because it highlights the possibility that some cases of chronic fatigue may be misattributed when undiagnosed Lyme borreliosis is the underlying cause. Understanding the overlap between CFS presentations and Lyme disease could improve diagnostic accuracy and guide appropriate treatment decisions.
Observed Findings
- Chronic fatigue syndrome can present alongside neuro-ocular manifestations (iritis, vitritis, optic disc changes) consistent with Lyme borreliosis
- Eye findings in suspected Lyme disease include chronic iritis with posterior synechiae, vitritis, and atypical pars planitis-like syndrome
- Multiple serological tests (IFA, ELISA, Western blot) and emerging PCR and urine antigen methods are available for Lyme detection
Inferred Conclusions
- Physicians should maintain clinical suspicion for Lyme borreliosis in patients presenting with CFS and specific neurological or ophthalmological features
- Systematic history-taking focused on tick exposure and geographic risk is essential in evaluating atypical presentations of CFS
- Multimodal laboratory testing improves diagnostic yield when Lyme borreliosis is suspected in CFS cases
Remaining Questions
- What proportion of patients clinically diagnosed with CFS actually have undiagnosed Lyme borreliosis?
- What is the sensitivity and specificity of the proposed diagnostic algorithm and laboratory panel in a prospective cohort?
- How does treatment of Lyme borreliosis affect symptoms in patients initially diagnosed with CFS?
- Which specific neuro-ocular findings are most predictive of underlying Lyme infection in CFS patients?
What This Study Does Not Prove
This study does not prove that Lyme borreliosis causes or explains most CFS cases, nor does it establish the prevalence of Lyme infection among CFS patients. It is a clinical review proposing diagnostic criteria rather than a controlled study demonstrating the frequency of this misdiagnosis or comparing treatment outcomes between Lyme-positive and Lyme-negative CFS cohorts.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
