Abstract (2. Language):
The full-field electroretinogram (ffERG) was used as an electrophysiological test of retinal function. The
electrophysiology activity of the photoreceptors in the retina was investigated using photopic adapted full-field
electroretinogram (ffERG) in a sample of Malay ethnic (Melayu), (mean 21.72 ± 0.88 years old). About 10 minutes room
illumination of photopic adaptation was used, single flashes of 3 cd.s.m-2 presented until 4 similar artifact free ERG
waveforms, and 30 Hz flickers ERG was averaged based on 15 sweeps of 250 milliseconds (ms) duration, which based on the
International Society of Clinical Electrophysiology of Vision (ISCEV) 2008 ERG Standard. The mean, standard deviation and
median of amplitude (μV) of cone a-wave (-30.73 ± 12.49, -29.22) and cone b-wave (119.26 ± 37.76, 119.45), and the latency
time (ms) of cone a-wave (14.30 ± 1.15, 14.50) and cone b-wave (30.02 ± 0.98, 30.00), 30 Hz peak amplitude (97.12 ± 28.63,
86.51), and latency time for peak (26.27 ± 1.77, 26.00) and trough (13.13 ± 2.10, 13.00) respectively were shown in
descriptive data. The normal value of young Malay adults as the baseline data for Malay population and comparable to other
population around the world is important for ffERG practical.
