Response rate to one-step operation of exotropia with over sixty prism diopters of deviation at Imam Khomeini Hospital, Urmia

Information about the results of strabismus surgery conducted in accredited domestic educational and
medical centers can result in knowing medical status of strabismus surgery in the country. The present study was
aimed at specifying the results of exotropia surgery with over 60 prism diopters of deviation. Method: The present
study is a descriptive-retrospective study that was conducted over two years (2007-2008) at Imam Khomeini
Hospital, Orumia. Random sampling was utilized. The study consisted of forty patients who were diagnosed with
symptoms of over-60 prism diopter horizontal ocular deviation of exotropia and underwent surgery. Findings: In
the present study, 40 patients with exotropic deviation of over 60 prism diopters and with a mean age of
25.27±11.89 received resection and recession (R&R). Twenty-four patients (60%) were male and 16 (40%) were
female. The operation was conducted on the right eye and the left one for thirteen (32.5%) and 7 (17.5%) patients,
respectively. However, alternative exotropia was conducted for 20 patients (50%). Conclusion: Generally, the
results of exotropia resection and recession surgery at Imam Khomeini Hospital of Orumia has been acceptable and
satisfactory. However, selecting patients for operation plays an important role in reaching better results after the
operation.
