Purpose: To evaluate the effect of periosteal fixation in patients with large-angle paralytic strabismus that was not corrected through conventional strabismus surgery.
Methods: Four eyes of three patients with large-angle paralytic strabismus who underwent periosteal fixation from June 2014 to August 2014 were examined. All patients presented with exotropia > 50 prism diopters (PD). Two of them showed exotropia caused by chronic complete oculomotor nerve palsy; the other two showed exotropia caused by medial rectus muscle injury during endoscopic sinus surgery.
Results: The mean preoperative exodeviation using the Krimsky test was 58 ± 29 PD. The postoperative values were 6.5 ± 9.4 PD at 1 week, and 11.25 ± 2.5 PD at 6 months. The mean surgical effect of exodeviation was 43.75 ± 21.36 PD.
Conclusions: Periosteal fixation is an effective surgery for the management of paralytic strabismus that was not corrected through conventional strabismus surgery.
