Abstract:
Photodocumentation of allergic hyperemia induced during the conjunctival provocation test (CPT) is analyzed by digital imaging and by assessment from an external observer. Selected specific characteristics, derived from the measured conjunctival redness values, represent the relevance of digital imaging and reproducibility of the CPT. The characteristics discussed here are: the area under the ROC curve and Pearson's product-moment correlation coefficient.
