A Quantitative Method for Assessing the Degree of Axial Proptosis in Relation to Orbital Tissue Involvement in Graves’ Orbitopathy – Corrected Proof

Purpose: To define a method of quantifying axial proptosis in patients with Graves' orbitopathy (GO) and to validate a score that correlates with the orbital involvement and helps determine the degree of proptosis correction for elective orbital decompression. Design: Retrospective, case series. Participants: The study included 50 patients (group A) and 29 control subjects who underwent orbital computed tomography (CT). The method was then validated in another group of 21 patients with GO (group B). Methods: The orbital area (OA) was measured manually on the central axial section of the CT scan at a level where the lens is visualized. (Read more...)
