vision/eye

abnormal eye electrophysiology ( J:50824 )

• does not display electroretinographic (ERG) b-waves (J:50824)

• ERG finding is observed by day 18 (J:50824)

abnormal cone electrophysiology ( J:50824 )

• light-adapted cone ERG retains a negative polarity (J:50824)

abnormal rod electrophysiology ( J:50824 )

• dark-adapted rod ERG retains a negative polarity even with increasing stimulus intensity (J:50824)

absent visual evoked potential ( J:50824 )

• no response to visual evoked potential at flash onset and slight response at flash offset (J:50824)

abnormal vision ( J:81028 )

• decreased light sensitivity (J:81028)

abnormal cone electrophysiology ( J:123811 )

• light adapted ERG is reduced in amplitude and has slower kinetics as compared to control (J:123811)

• implicit time of the b-wave is delayed (J:123811)

• cone ERG amplitude has a distinctive waveform as compared to control (J:123811)

abnormal rod electrophysiology ( J:123811 )

• b-wave is absent in dark-adapted electroretinogram (ERG) (J:123811)
