ABSTRACT
PURPOSE:
To determine the location of contour abnormalities in Graves upper eyelid retraction.METHODS:
Multiple midpupil angular eyelid distances of 75 upper eyelids of 55 patients (mean age = 41.7 ± 13.3 SD years) in the inactive phase of Graves orbitopathy were measured with a recently developed custom-made software. Sixty eyelids of 60 normal subjects were also measured as a control group. A contour peak was defined by the highest midpupil angular eyelid distance normalized (divided) by the superior limit of normality (mean + 2SD).RESULTS:
In 45 eyelids (60%), the peaks were lateral between 120° and 150°. For high levels of retraction, the peaks tended to be centrally located with a substantial number of medial deformities (30 eyelids). Although the lateral and medial peaks were not affected by exophthalmometry, there was a statistically significant increase of medial peaks when midpupil eyelid distance was greater than 6.75 mm (χ = 5.20, p = 0.02).CONCLUSIONS:
Lateral contour abnormalities are more frequent than medial deformities. With minor degrees of retraction, there is a predominance of lateral peaks. With higher degrees of retraction, the number of medial abnormalities is similar to the lateral ones.
