Abstract
Purpose :
To revise diagnostic criteria for ocular sarcoidosis (OS) established by the International Workshop on Ocular Sarcoidosis (IWOS) in 2006 (Ocul Immunol Infl, 2009;17:160-9).
Methods :
A consensus workshop was held in April 2017, in Bali, Indonesia, to revise the IWOS criteria. Prior to this workshop, a questionnaire proposing revised criteria and consisting of one item for differential diagnosis, 7 items for ocular clinical signs, 10 items for systemic investigations and 3 classes of diagnostic criteria was circulated to 36 uveitis specialists in 15 countries. Questionnaire items with >75% agreement were taken as consensus agreement; items with <50% agreement were taken as consensus disagreement and items with 50-75% agreement were discussion at the workshop. The later items that were supported by two-thirds of 27 IWOS panelists from 14 countries were taken as consensus agreement.
Results :
Thirty of 36 uveitis specialists replied to the questionnaire (83% recovery rate). Fifteen questionnaire items with >75% agreements were incorporated into the revised criteria without discussion at the workshop. Items with <50% agreement were excluded from the revised criteria. Items with 50-75% agreement, which were identified for discussion and vote at the workshop were: bilaterality in ocular signs; increased serum soluble IL-2 receptor and serum Ca in systemic investigations; and definition of probable OS in the diagnostic criteria. At the workshop, new systemic investigations were raised for discussion and vote, including: lymphopenia; increased vitreous CD4/CD8 ratio; and parenchymal lung changes consistent with sarcoidosis. After discussion, bilaterality, lymphopenia, lung parenchymal changes and definition of probable ocular sarcoidosis were supported by a two-third majority of the 27 IWOS panelists, and taken as consensus agreement.
Conclusions :
Revised IWOS criteria for the diagnosis of OS have been established for validation in future studies (Table 1).
