Usefulness of Exophthalmos Measurement on Upgaze

Purpose: To evaluate the usefulness of exophthalmos measurement on upgaze in patients who are not able to expose corneal vertex on primary gaze. Methods: The present study included 39 patients with blow out fracture, pseudotumor, or thyroid associated ophthalmopathy and 21 people who don’t have any ocular disease. In total, 60 people had exophthalmometry using Hertel exophthalmometer on the basis of corneal vertex, inferior limbus, and inferior sclera by three examiners. Results: The relative exophthalmometry in normal group was 0.71 ± 0.75 mm, 0.67 ± 0.62 mm, and 0.69 ± 0.60 mm on the basis of corneal vertex, inferior limbus, and inferior sclera, respectively. The relative exophthalmometry in exophthalmic group was 1.10 ± 0.99 mm, 1.13 ± 0.99 mm, 1.10 ± 0.91 mm on the basis of corneal vertex, inferior limbus, and inferior sclera, respectively. The relative exophthalmometry in enophthalmic group was 0.79 ± 0.90 mm, 0.74 ± 0.92 mm, 0.74 ± 0.87 mm on the basis of corneal vertex, inferior limbus, and inferior sclera, respectively. There was no statistically significant difference between different measuring points (p > 0.05). The inter-examiner reproducibility was shown to be highly reliable. Conclusions: The upgaze exophthalmometry on the basis of inferior limbus or inferior sclera would be useful in the patients who are not able to expose corneal vertex on primary gaze.
