  • Abstract
  • Look Inside

 A 27-year-old woman presented with impairment of vision and photophobia. Photophobia and difficulty in color discrimination had started at the age of 14 years. She had negative family history. Occult macular dystrophy had been suspected by the referring ophthalmologist because of normal fundus finding,central scotoma,and normal electroretinogram(ERG)elicited by strong full-field flash. Her corrected visual acuity was 0.1 in either eye. Both eyes showed normal funduscopic and fluorescein angiographic findings. Full-field ERG showed normal rod and rod-cone responses and absence of photopic or cone response. Occult macular dystrophy is characterized by normal cone ERG and by abnormal macular or multifocal ERG. We therefore diagnosed this patient with cone dystrophy.
