Introduction: Bartonella henselae causes cat scratch disease (CSD), spread by a cat scratch or bite. Cats are its main reservoir. This sometimes results in optic neuritis or neuroretinitis.
Objective: To review these conditions in Gipuzkoa (Spain), 2014-2019.
Methods: A retrospective review of serology and clinical records, selecting those with consistent clinical signs, contact with cats and positive serology for B. henselae (IgG-IFA≥1/256).
Results: Sixty-four patients had CSD. Of these, one had optic neuritis and 3 had neuroretinitis (4/64; 6.3%). In 3 patients, flu-like symptoms preceded eye symptoms. Two suffered from loss of visual acuity at discharge, despite prolonged treatment with antibiotics and corticosteroids.
Conclusion: Optic neuritis and neuroretinitis caused by B. henselae are severe complications with a non-negligible incidence among patients with CSD in Gipuzkoa. We recommend ruling out CSD in patients with symptoms of optic neuritis or neuroretinitis (sudden vision loss, etc.) and contact with cats.
