Dengue fever is a viral disease transmitted by Aedes mosquitoes and is endemic in the tropics.1 The severity of dengue fever varies from mild non-specific febrile illness to potentially fatal dengue haemorrhagic fever causing thrombocytopenia and shock. Patients with dengue fever may develop various ophthalmic manifestations causing visual loss, including macular oedema, macular haemorrhage, retinal vasculitis, “cotton-wool” spots and optic disc swelling.2–8 We report the use of multifocal electroretinography (mfERG) in the assessment of a patient with dengue fever-associated maculopathy in whom there were no clinical or angiographic abnormalities.
