Assessment of a 3-dimensional computerised PASI Tool for calculating and documenting psoriasis area and severity index scores

Psoriasis Area and Severity Index(PASI) scoring was initially developed by Fredriksson and Pettersson in 1978[1], as a method to clinically evaluate and quantitate the amount and severity of psoriasis, and therefore the responses to a new treatment. Despite its advantages, there are numerous limitations such as high intra- and inter-observer variability and reproducibility in assessment of each of the PASI parameters[2], with scores varying two or three fold between scorers[2-5].
