STANDARDIZED GRADING SCALES FOR UVEITIS

STANDARDIZED GRADING SCALES FOR UVEITIS

One of the difficulties in uveitis management is the inconsistency of grading scales used by practitioners. In an effort to better organize the classification and grading of various uveitic entities, the Standardization of Uveitis Nomenclature (SUN) Working Group developed a process to standardize the approach to reporting clinical data in research to help all clinicians improve consistency in grading.5
