Evaluation of Ocular Versions in Graves’ Orbitopathy: Correlation between the Qualitative Clinical Method and the Quantitative Photographic Method

Table 1

Agreement between qualitative clinical categories and quantitative photographic measurements of version in 5 positions of gaze (abduction, adduction, elevation in abduction, elevation, and elevation in adduction) in a sample of 42 patients with GO.
