Choose referral criteria
The examiner can choose
between five different ROC
curves (Receiver Operating
Characteristics), which differ in
sensitivity and specificity, due to
different studies. ROC 1 is the
pre-set curve, which is based on
a study of the University Eye
Hospital Munich.
To perform screenings with
lower sensitivity but higher
specificity choose one of the
other ROC curves (2-5). Keep in mind that choosing a lower sensitivity will
increase the number of positive children, who are overlooked.
