Background: Cat scratch disease (CSD) is caused by the Gram-negative bacterium Bartonella henselae. In rare cases, the initial infection results in ocular and neurological complications. We report a case of macular hole retinal detachment that developed as a complication of CSD.
Case: On referral to our hospital, a 12-year-old girl presented with a history of decreased visual acuity in the left eye. Her left corrected visual acuity was 0.1. Fundus examination revealed swelling of the optic disc and macular hole retinal detachment in the left eye. Fluorescein angiography showed hyperfluorescence in the left optic disk. The patient's blood was positive for anti-B. henselae immunoglobulin (Ig) G and IgM antibodies. We diagnosed CSD and treated the patient with systemic antibiotics and a corticosteroid. After the improvement of the patient's neuroretinitis, the findings of vitreous traction of the macula improved but those of the macular hole and subretinal fluid did not. We therefore performed a vitrectomy. The macular hole was successfully closed, and the patient's visual acuity improved.
Conclusions: Macular hole retinal detachment as a complication of CSD is a rare entity. After undergoing vitrectomy following pharmacotherapy, our patient followed a favorable course.
