摘要: OBJECTIVES: The objective of this study was to evaluate the ability a muscular index (Barrett's Index), calculated with multidetector computed tomography, detect dysthyroid optic neuropathy in patients Graves' orbitopathy. METHODS: Thirty-six orbitopathy were prospectively studied and submitted neuro-ophthalmic evaluation tomography scans orbits. Orbits divided into two groups: those without neuropathy. Barrett's as percentage orbit occupied by muscles. Sensitivity specificity determined for several values. RESULTS: Sixty-four orbits (19 45 neuropathy) met inclusion criteria study. mean values (± SD) 64.47% ± 6.06% 49.44% 10.94%in groups neuropathy, respectively (p 60% should be carefully examined followed development
