How is anterior ischemic optic neuropathy diagnosed?

  • Tests for visual acuity (clarity) and visual field (to gauge any central or peripheral vision loss).
  • Measurement of pressure within the eye (intraocular pressure).
  • A dilated eye exam to detect any damage to the optic nerve.
  • Measurement of overall blood pressure.
  • Obtaining both Erythrocyte Sedimentation Rate (ESR) and C-reactive protein (CRP) blood tests and platelet count (CBC).
  • Other blood work to detect conditions such as diabetes, vascular disease, anemia, or high cholesterol.
  • Biopsies of arteries in the temple area of the head to determine if arterial inflammation is present.
  • Injection of dye into arteries of the head for the purpose of fluorescein angiography, in which pictures of the blood vessels are taken to determine where blood flow may be interrupted.
