How Reproducible Are These Assessments?
ОглавлениеThere are no peer-reviewed publications on the reproducibility of eyelid dimensions in GO although unpublished data from the co-author’s institution show that the intraclass correlation for palpebral aperture was good at 0.65. Eyelid dimensions in ptosis subjects have been found to be highly repeatable [63]; however, patients with GO frequently exhibit marked variability in upper eyelid positions and are likely to be more difficult to measure accurately.
Exophthalmos accuracy depends significantly on the model of exophthalmometer used together with technique. The Hertel exophthalmometer with straight footplates and a single mirror appears to be more accurate than other Hertel models [54], and although other types of exophthalmometer may be more reliable [64], they are much less commonly available. Reproducibility to within 2 mm is generally quoted [4, 51, 52], and unpublished data from the co-author’s institution showed the intraclass correlation to be 0.71 for exophthalmometry.
Both UFOF and BSV measurements show high levels of accuracy with UFOF repeatable to within 8° for single muscle measurement [56], and BSV fields accurate to within 4%.
The reproducibility of assessments for DON is unknown.
