Abstract

AIM:To examine the frequency of different types of strabismus and surgical outcomes in Yazd, Iran.METHODS: In this descriptive study, medical records of all strabismus patients aged below 16 years with at least 6 months follow-up were reviewed. Data on surgical outcomes and complications were collected from questionnaires and analyzed statistically. Chi-square for qualititative and Mann-Whitney tests for quantitative variables were used.RESULTS: Six hundred and eighty-five cases of childhood strabismus were identified during an 11-year study period. The following types of strabismus were identified: 307 cases(44.8%)with exotropia, 294(42.9%)with esotropia and 84(12.2%)combined horizontal and vertical cases. The post-operative alignment in 280 cases(73.9%)was normal(range of horizontal deviation Δ).CONCLUSION: The most common type of strabismus in this study is exotropia. Outcomes of surgery are comparable to those published in the literature. A longer follow-up is needed to further evaluate the results.
