Visual Evoked Potential and Glaucoma management- A Review

Visual Evoked Potential (VEP) It is part of the total, gross, electrical brain activity known as the electroencephalogram and offers the potential of providing earlier and more specific objective functional testing than currently available with subjective threshold visual fields. With newer imaging methods such as Ocular Coherence Tomography (OCT), we have made significant strides in earlier detection of structural damage to the optic nerve and nerve fiber layer, while our ability to detect functional loss earlier than what we achieve via white on white threshold field analysis remains a challenge in glaucoma
