Autoimmune neuroretinopathy secondary to Zika virus infection

Case report: A 40-year-old woman diagnosed with Zika virus infection 6 months before she arrived at this hospital. She referred to a progressive and painless vision loss, of 2 weeks onset after the infection diagnosis. She was treated with topical steroids. Previous visual acuity was recovered, but she still refers to reduced visual field and nyctalopia. Ophthalmologic examination revealed severe retinal sequels, compatible with autoimmune retinopathy. Based on the clinical features and the temporal relationship with Zika virus infection, non-para-neoplastic autoimmune retinopathy was diagnosed and managed with steroids and infliximab.

Discussion: Zika virus can trigger a non-para-neoplastic autoimmune retinopathy. The diagnosis is based on clinical features, and requires early immunosuppressive therapy.
