With an abnormal VEP, the differential diagnostic considerations include the following:

  • Optic neuropathy

  • Optic neuritis

  • Ocular hypertension

  • Glaucoma [9, 10]

  • Diabetes - Szabela et al found abnormal VEP in 22% of type 2 diabetics [11]

  • Toxic amblyopia

  • Leber hereditary optic neuropathy

  • Aluminum neurotoxicity [12]

  • Manganese intoxication [13]

  • Retrobulbar neuritis

  • Ischemic optic neuropathy

  • MS [14]

  • Tumors compressing the optic nerve - Optic nerve gliomas, meningiomas, craniopharyngiomas, giant aneurysms, and pituitary tumors
