Retinitis in Lyme Disease
Inflammation of the retina usually caused by Borrelia burgdorferi.
The incidence of this retinal disorder has increased in recentyears.
The inflammation is caused by spirochetes usually transmitted bybites from infected ticks.
Lyme disease can lead to many inflammatory ocu-lar changes with their respective symptoms. These include conjunctivitis, keratitis, and iridocyclitis. Retinal vasculitis, retinal artery occlusion, neu-roretinitis, optic neuritis, and choroiditis have also been described.
Lyme disease should be excluded as a possible cause of posterior uveitis of uncertain etiology.
The diagnosis is made by ophthalmoscopy andserologic studies to identify the pathogen.
Inflammatory ocular changes due to other causes(such as toxoplasmosis or tuberculosis) should be excluded.
Antibiotic treatment with tetracycline, penicillin G, or third-generation cephalosporins is indicated.
Retinal changes due to Lyme disease tend torecur.
