Abstract :

Recording of visual impulses is an important task in case of subjects whom ordinary recording of such techniques are impossible. Visual Evoked Potential (VEP) and Electroretinography (ERG) are among the visual impulses that are performed in neonatal subjects with naturally no cooperation. To overcome this drawback these two techniques is performed under anesthesia. In this regard it is observed that the ERG pattern obtained in these subjects under anesthesia are more reliable than VEP one, therefore the aim of present work is an attempt to look for reliability of ERG and VEP recording under anesthesia in neonatal subjects.

Fifty neonates referred to university polyclinic for VEP and ERG examinations were selected. Conventional electrode attachment was used to connect the electrodes to the patients. The patterns obtained were analyzed by ophthalmologist to check for the reliability of the patterns obtained.

The result obtained showed ERG patterns are more reliable in comparison to VEP one.

According to result of present work it can be concluded that ERG patterns are more reliable and the possible reason is that ERG is extracted from limited layers of retina where the complexity is less in comparison to VEP patterns which is extracted from visual pathway which starts from retina & ends up to visual cortex in ain.
