[Aus-soaring] Re: Peripheral Visual Fields

[David Long &/or Cathy Lincoln]

So this is actually not a test of peripheral visual fields and gives no reassurance for this important visual feature for driving or flying.  Interesting.  It might be an objective test, but it is testing something different from some people's expectations and they have been falsely reassured.  This is one problem with tests.  And it's not free.  If it's paid for by Medicare and health insurance, you (and I) have paid for it.   Dave Long   With respect to gliding it is not really an indicator of your peripheral vision. The test is actually only checking the quality of your central visual field, (where early glaucoma damage is found). The normal test goes out to 24 or 30 degrees. Whereas the normal visual field extends 50 degrees superiorly, 70 degrees inferiorly, 90 degrees temporally and 60 degrees nasally. So it is theoretically possible to have a peripheral field loss that would not show up with central testing.   MT
