In cooperation with staff from Melbourne University, School of Optometry, using a Humphrey Field Analyser (this is the leading computerised automated visual field tester in the world, costing $42,000.00). which measures sensitivity thresholds to light in the peripheral and central fields; this project aims to determine if there is any increase in peripheral  and central field sensitivity of adjusted subjects over non-adjusted subjects. If this computer finds any inconsistencies in subject response, it will retest part of the examination until a consistent response is found.
There will be 10 treated and 10 control subjects. Visual thresholds will be determined into right. eye at +5,+5°; +5°-5°; -5°,+5°; -5,-5° for central vision and +20″,+2 +4C,,+20″;+2Ci-2a°; +4 -2()’\ -20″,+2 and -20°,-20- degrees for peripheral vision. This also checks both occipital cortexes. All subjects will be tested, then retested and then before the third test, half (10) subjects will be adjusted without. the computer operator knowing who has been treated. This number of retests is necessary to accommodate a peripheral learning effect. The results will then be statistically analysed to determine if vision in the peripheral and/or central fields becomes more sensitive to a given stimulus following. chiropractic adjustment.
