UNLABELLED: Cochlear implants (CIs) are a successful alternative in cases with severe-to-profound HL. In these individuals, visual cross-modal re-organization can occur because of hearing loss where the visual cortex will recruit auditory cortical areas for visual processing.
OBJECTIVES: This work is designed to study visual evoked potentials (VEPs) in children fitted with CIs in comparison to normal hearing children.
METHOD: This work included 2 groups of children: Group I included 20 normal hearing children and study group included 25 children fitted with unilateral CIs. All cases were subjected to Thorough otological history. Check up on CIs performance using physical check and Aided sound field examination, ophthalmic examination and Pattern Visual Evoked Potentials (pVEPs).
RESULTS: Both groups showed no significant difference as regard age or sex. And both had normal ophthalmic examinations. Children of the study groups showed satisfactory aided response. As regard pVEPs, the study group showed significant higher P100 amplitude in comparison to the control group.
CONCLUSION: This study showed that deafness could induced cortical organization in the visual cortex and not limited to the auditory cortex only.
