Bartonella henselae infection associated with neuroretinitis, central retinal artery and vein occlusion, neovascular glaucoma, and severe vision loss.

Purpose: To report a case of Bartonella henselae infection.
Design: Observational case report.
Methods: Review of the clinical, laboratory, photographic, and angiographic records of a patient with cat scratch disease associated with central retinal artery and vein occlusion, neovascular glaucoma, and severe vision loss.
Results: A 21-year-old man had no light perception in the left eye secondary to concurrent central retinal artery and vein occlusion believed to have resulted from infection with Bartonella henselae. Forty days later, he developed neovascular glaucoma in the left eye.
Conclusion: Ocular complications associated with Bartonella henselae infection may include central retinal artery and vein occlusion, neovascular glaucoma, and severe vision loss.
