Post-infectious Non-paraneoplastic Autoimmune Retinopathy in Paediatric age group: A high index of suspicion, Multimodal Imaging and Early treatment can restore vision.

Abstract Purpose: To report a case of non-paraneoplastic Auto-immune retinopathy (npAIR) in a paediatric patient who showed excellent visual recovery with early diagnosis and prompt treatment. Methods: Retrospective Case report Results: A five year old girl presented to us with bilateral profound vision loss of sub-acute onset following an episode of high fever, without any previous visual abnormality. A diagnosis of npAIR was made based on history, clinical findings and multimodal imaging. Intravenous methylprednisolone was started urgently followed by oral steroid. Visual acuity showed good improvement along with gradual restoration of anatomy of retinal layers in Optical Coherence Tomography (OCT) over a period of three months. Conclusion: Our case highlights the importance of suspecting npAIR in paediatric patients presenting with sudden bilateral painless progressive loss of vision without prior visual difficulties and the role of multimodal imaging to aid in diagnosis. The recovery of vision with restoration of photoreceptor layer also shows the nature of the disease to recover with early intervention despite a negative anti-retinal antibody test but with features highly suggestive of npAIR.
