Fig. 1From: Correlation between uniocular deviation and duction changes following different decompression surgeries in thyroid eye diseaseOcular duction was evaluated using Hirschberg’s method. Light target on the surface of the eye at limbus = 45°, between limbus and pupil = 30°, and at pupil edge = 15° (solid arrow). The space between these designations was divided into thirds, and intermediate duction was estimated to the nearest 5° (dotted arrow). This patient is looking inward at 25°Back to article page
