Terry   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   _______________________________________________ Aus-soaring mailing list [EMAIL PROTECTED] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
