Peripheral neuropathy and haemolytic anaemia with cherry red spot on macula in dapsone poisoning.

A young female presented with haemolytic anaemia due to dapsone overdosage. She developed peripheral neuropathy and marked visual impairment with a cherry red spot on the macula, possibly due to toxic retinal vascular damage; both these resolved in due course. Cherry red spot due to dapsone poisoning has not been reported previously.
