  • Abstract
  • Look Inside

A 33-year-old female presented with left visual field defect since one week before. Her corrected visual acuity was 1.5 in either eye. Funduscopic findings were inconspicuous. Perimetry showed enlarged blind spot in the left eye. Multifocal electroretinogram (MERG) showed decreased amplitude around the left optic disc. She was diag-nosed with acute idiopathic blind spot enlargement syndrome (AIBSE) and was given systemic prednisolone. The en-larged blind spot and subjective symptoms improved 2 weeks after onset. Findings by MERG remained unchanged. This case illustrates the usefulness of MERG in detecting subclinical retinal dysfunction in this syndrome.
