Delayed Lyme Disease Treatment Leads to Carditis and Vision Loss
Lyme disease can progress quickly when early symptoms are overlooked or ignored.
A 66-year-old man became ill within one week of a tick bite to the back of his neck. One month later, he collapsed and lost consciousness, according to Sharma and colleagues in The American Journal of Medicine.
Early Symptoms Were Missed
In the weeks before his collapse, the patient experienced intermittent malaise, chills, and episodes of lightheadedness.
Two days before presentation, he developed cloudy vision in his right eye.
He did not seek medical care until he experienced a witnessed syncopal episode. While walking across the room, he became lightheaded, attempted to steady himself, and then lost consciousness.
Diagnosis of Lyme Carditis and Optic Neuropathy
He was diagnosed with Lyme carditis and optic neuropathy.
Electrocardiogram findings included a junctional escape rhythm, left anterior fascicular block, and right bundle branch block—evidence of significant cardiac conduction involvement.
His sinus node dysfunction resolved rapidly after initiation of a 4-week course of intravenous ceftriaxone.
Incomplete Recovery
Despite improvement in cardiac function, the patient had only minimal recovery of vision in the affected eye.
This suggests that neurologic complications may not fully reverse once injury has occurred.
Clinical Implications
This case highlights the risks associated with delayed evaluation and treatment.
Earlier recognition of symptoms such as fatigue, chills, lightheadedness, and visual changes may have prevented progression to syncope, cardiac involvement, and permanent visual impairment.

Clinical Takeaway
Lyme disease can progress to serious cardiac and neurologic complications when early symptoms are not evaluated. Timely assessment remains critical, particularly in patients with recent tick exposure and evolving symptoms.

Here in NEPA there is no one to treat so it’s a waste of time and money to visit a doctor.
It can be difficult to find a doctor that will considers a tick borne illness as a factor.
