Chronic inflammatory demyelinating polyneuropathy (CIDP) is an autoimmune disorder predominantly affecting the peripheral nervous system (PNS), characterised by muscle weakness and sensory disruption which may involve all four limbs[1]. CIDP affecting children is uncommon, with a large scale review in 2013 noting 143 documented cases described in the literature [2]. Central nervous system involvement has previously been described; however, optic neuropathy is an extremely rare manifestation of CIDP, with only a small number of cases previously reported (both unilateral and bilateral) in adult patients[3-5]. This report details a child who developed optic neuropathy in association with CIDP.
