Term ID: 7984
Name: Electronegative electroretinogram
Synonym: Electronegative ERG; Electroretinogram: reduced b-wave amplitude; Reduced amplitude of dark-adapted bright flash electroretinogram b-wave; Reduced electroretinogram rod b-wave; Reduced ERG amplitude of b-wave
Definition: A dark-adapted bright flash electroretinogram in which the b-wave that is of markedly lower amplitude than the associated a-wave (source: Holder GE., Inherited Chorioretinal Dystrophies: A Textbook and Atlas; 2014; p.17; ISBN 978-3-540-69466-3).
