These revised charts incorporate a slight change in the difficulty score
for each of the ten Sloan letters
derived from the best visual acuity examinations of 7420 eyes during the ETDRS
study.The original* charts’
difficulty scores were derived from the examination of 234 eyes. In addition to
the revised arrangement of letters
which resulted in the ultimate homogeneity of difficulty per line, the three
charts are balanced so that in each
chart the ten letters are represented at least once in
every position.
