Interobserver Agreement in Grading Activity and Site of Inflammation in Eyes of Patients with Uveitis

Proposed methods for grading inflammatory activity have moderate reproducibility for exact agreement in most instances. However, agreement within 1 grade is excellent for grading of AC cells and vitreous haze. The method for grading the site of intraocular inflammation also produces moderate levels of agreement, and in our hands was improved by excluding both anterior and intermediate uveitis. Improved methods for grading AC flare and vitreous cells are needed.
