Purpose: To describe a case of interferon-beta retinopathy associated with paracentral acute middle maculopathy.
Case report: A 15-year-old girl with Epstein-Barr virus-positive advanced nasopharyngeal carcinoma WAS REFERRED with reduced visual acuity. Multimodal imaging findings, including optical coherence tomography angiography, at presentation and evolution following cessation of interferon therapy are presented.
Conclusion: The presentation of paracentral acute middle maculopathy in this patient supports the presumed ischaemic pathogenesis in interferon retinopathy. The imaging findings provide evidence of deep capillary plexus involvement in interferon retinopathy with evolution to permanent structural damage within the inner nuclear layer.
Keywords: Interferon-beta; multimodal imaging; optical coherence tomography; optical coherence tomography angiography; paracentral acute middle maculopathy.
