Purpose:
To describe a case of posterior uveitis with retinal vasculitis related to Ehrlichia exposure.
Patients And Methods:
Single case report of a 68-year-old woman with posterior uveitis, steroid-induced glaucoma, and retinal holes.
Results:
Ehrlichia titers were elevated 4-fold (1:256; normal <1:64) with an otherwise normal laboratory workup. The patient's cystoid macular edema responded to sub-Tenon's triamcinolone and oral doxycycline.
Conclusion:
To our knowledge, this is the first case of posterior uveitis associated with Ehrlichia reported in humans.
