Strander et al described a colposcopic score for evaluating women with atypical cervical cytology. The authors are from the University of Goteborg (Gothenburg) in Sweden.
The solutions used during colposcopy were 5% acetic acid and Schiller’s solution (iodine).
Parameters:
(1) acetowhiteness
(2) lesion size
(3) vascular pattern
(4) margins and surface
(5) staining with iodine

total score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 10
• The higher the score the greater the risk for high grade cervical dysplasia.
