Abstract

PURPOSE. To investigate diplopia after orbital decompression in patients with thyroid-related orbitopathy. METHODS. We retrospectively analyzed medical records of 45 consecutive patients who had undergone orbital decompression surgery (DS) and a subgroup of 10/45 patients who underwent disinsertion of the inferior oblique (IO) muscle during DS. Diplopia was assessed before DS and 1 and 3 months after DS. Residual strabismus defects were treated surgically approximately 3 months after DS with follow-up visits 1 week, 3 months, and 6 months postoperatively. Patients with horizontal or vertical diplopia were evaluated using the alternate prism-and-cover test and torsional diplopia (TD) using a double Maddox rod test to quantitate their strabismus. RESULTS. Strabismus surgery was effective in treating the horizontal and vertical diplopia (13/40 cases with residual deviations required prism glasses), but did not resolve the TD. None of the patients with IO disinsertion during DS complained of TD before strabismus surgery. However, after strabismus surgery, TD occurred in all 10 patients with IO disinsertion vs 8/30 patients without IO disinsertion (p
