Diagnosing aura

When are migraine-associated visual symptoms an aura, and when are they not? Most of the time it doesn’t matter, but it becomes of vital importance when assessing a woman’s suitability for oestrogen-containing contraception. Fortunately, the JFPRHC has just published an article with guidance on answering this: the VARS (Visual Aura Rating Scale) score. Characteristics of the abnormal visual symptoms are scored thusly:

  • Duration 5 – 60 mins:                                       3
  • Develops gradually over 5 0r more mins:    2
  • Blank spot in vision (scotoma):                     2
  • Zigzag line (fortification spectra):                2
  • Homonymous hemianopia:                           1

5 or more points diagnoses an aura.
