Are the Standardization of the Uveitis Nomenclature (SUN) Working Group criteria for Codifying the Site of Inflammation Appropriate for All Uveitis Problems? Limitations of the SUN Working Group Classification.

The standardization of Uveitis Nomenclature (SUN) Working Group recently affirmed the importance of an anatomic classification of uveitis, endorsing the anatomic clasiffication scheme proposed by the International Uveitis Study Group (IUSG). The group however pointed out and addressed ambiguities in the IUSG system, and proposed new standards for grading the anatomic location and degree of activity of inflammation. Besides clarifying some of the existing nomenclature problems the terminology proposed by the SUN working group still remains confusing in a few points. Ambiguities in the SUN Working group anatomic classification of uveitis were addressed, especially regarding the terms “pars planitis“, “neuroretinitis“ and “anterior and intermediate uveitis“.
