Abstract

Purpose: To compare 2-dimensional palpebral fissure measurements of normal subjects with voluntary upper eyelid retraction and patients with Graves upper eyelid retraction. Methods: Three groups of monocular palpebral fissure images were measured. Group 1 consisted of 32 images of healthy subjects with the upper eyelid in a normal position of rest. Group 2 included the same subjects with voluntary upper eyelid retraction. Group 3 included 45 images of patients with Graves upper eyelid retraction. Fissure images were acquired with a digital camera and transferred to a Macintosh computer. For all images, three variables were quantified with NIH Image software: the midpupil-to-upper eyelid margin distance and the nasal and temporal upper areas of the palpebral fissure. Results: Voluntary upper eyelid retraction significantly increases the absolute difference between the temporal and nasal areas of normal subjects. The disproportion between the lateral and medial areas of the palpebral fissure was greater for the patients with Graves than for the control group with voluntary eyelid retraction, even though there was no difference between the midpupil-to-upper eyelid margin distance of these two groups. Overall, there was a positive correlation between the midpupil-to-upper eyelid margin distance and absolute difference between the temporal and nasal areas (r=0.75, P
