Correlation between uniocular deviation and duction changes following different decompression surgeries in thyroid eye disease

Abstract Background Postoperative ocular imbalance is an important problem for orbital decompression surgery in thyroid eye disease (TED). The aim of this study was to evaluate the changes unilateral deviation and duction following discuss biomechanics imbalance. Methods Fifty-four TED patients who underwent were included. Fifteen 1-wall (deep lateral wall) decompression, 18 2-wall medial 21 3-wall lateral, inferior decompression. Objective subjective operated eyes evaluated using prism test synoptophore, respectively. Ocular ductions measured Hirschberg’s method. diameters extraocular rectus by computed tomography. Results showed no significant difference after ( p = 0.25–0.89). Esotropia increased 0.001–0.02), hypotropia 0.02). Adduction but abduction decreased < 0.05). Infraduction 0.001). Additionally, increase esotropia significantly correlated with adduction decrease r 0.37–0.63, There correlations between diameter esotropia, postoperatively 0.35–0.48, Conclusions different 1-wall, contractile force may be reason strabismus surgery.
