The measurement of ERG (Electro-retinogram) including dark-adaptation time (before, 0, 5, 10, 15, 30, 45 and 60 min) of the anesthetized common marmoset aged 2-5 years was investigated in comparison with that of the anesthetized cynomolgus monkey aged 3 years. The ERG of the common marmoset could be measured with the use of an appropriately designed contact lens-typed electrode (diameter, 7.6mm; corneal radius, 3.5mm; sclerotic radius, 4.5mm).
The waves consisted of a- and b-wave and several small oscillatory potential, and reached a maximum at 15 min, but more rapid in the common marmoset than in the cynomolgus monkey. The measurement of ERG in the anesthetized common marmoset was possible by the use of a contact lens-typed electrode, and no large differences in the wave were recognized as compared with that of the cynomolgus monkey.
