BARTONELLA HENSELAE NEURORETINITIS ASSOCIATED WITH CENTRAL RETINAL VEIN OCCLUSION, CHOROIDAL ISCHEMIA, AND ISCHEMIC OPTIC NEUROPATHY.

Purpose: We describe a healthy 37-year-old man with Bartonella henselae (B. henselae) neuroretinitis with concurrent central retinal vein occlusion and ischemic optic neuropathy resulting in optic atrophy and choroidal ischemia.
Methods: Case report.
Results: A 37-year-old man presented with unilateral decreased vision and a fundus examination consistent with neuroretinitis. Further imaging review supported a concurrent diagnosis of central retinal vein occlusion. Although initially negative, repeat serological testing for B. henselae infection was positive. Multimodal imaging displayed severe outer retinal disruption, ischemic optic neuropathy, and choroidal ischemia. The patient demonstrated near complete resolution of fundus findings and restoration of outer retinal architecture. Residual findings included optic disk pallor and ischemic choroidopathy.
Discussion: B. henselae neuroretinitis may be associated with concurrent retinal vascular occlusive disease and ischemic optic neuropathy. Central retinal vein occlusion and choroidal ischemia leading to optic nerve atrophy are additional sequelae further expanding the clinical spectrum of this entity.
