Baytaroğlu A, Şekeroğlu HT, Turan KE, et al. - Researchers intended to determine if there is an association between clinical characteristics and histopathological and immunohistochemical features of inferior oblique muscles in patients with primary and secondary inferior oblique overaction. Inferior oblique muscle specimens of patients who had inferior oblique–weakening procedures for primary or secondary inferior oblique overaction have been selected. The sample consisted of 51 patients. No association was found between the clinical amount of inferior oblique muscle overaction and immunohistochemical markers. The variations in immunohistochemical parameters that are confirmed by histopathological changes between different etiologies of strabismus indicate that the behaviour of the satellite cell population differs between types of strabismus.
