A New Method for Grading the Severity of Keratoconus: The Keratoconus Severity Score (KSS) | IOVS | ARVO Journals
Purpose: : To determine the reliability and validity of a new method for grading the severity of keratoconus, the Keratoconus Severity Score (KSS). Methods: : The KSS is a 0-5 point severity scale using common clinical markers plus two corneal topographic indices. An initial test set of 1,012 eyes, including normal eyes, eyes with abnormal corneal and topographic findings but not keratoconus and eyes with keratoconus having a wide range of severity, was used to determine cut points for the KSS. Validation set 1 comprised of data from 128 eyes was graded by KSS and compared to a "clinicians ranking" of severity to determine if the scale fairly represented how a clinician would grade disease severity. Kappa statistics, sensitivity and specificity were calculated. A computer program was developed to automate the determination of the score. This was tested against a manual assignment of KSS in 2,121 (validation set 2) eyes from the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study as ...http://iovs.arvojournals.org/article.aspx?articleid=2391173
