GCC, VEP and RAPDx – Page 31 of 39

Diopsys VEPs were obtained under NOVA-DN conditions . The amplitudes of the VEP under both high contrast and low contrast conditions were normal in both eyes. However, the latency was abnormal under all conditions tested. The normal amplitudes are consistent with the normal VA but the large latency increases clearly indicate a bilateral optic neuropathy. Automated visual fields were attempted but due to ADHD were not possible on either of two visits.
