Abstract:AIM: To discuss the effect of different surgical methods effect on convergence insufficiency intermittent exotropia. METHODS: Ninety-eight recorded patients with convergence insufficiency intermittent exotropia were categorized into two groups. Group A was with the operations based on weakening procedure of the abductor oculi, group B with strengthening procedure of adducens oculi.Curative effects were analyzed in one year’s regular follow-up examinations. RESULTS: One year after surgery, the total correction rale was 88%, 86% in group A and 90% in group B. There were no obvious differences. From the comparison on convergence, group B was better than group A (P<0.05). CONCLUSION: The good surgical effect will be got based on either weakening procedure of the abductor oculi or strengthening procedure of adducens oculi, but the convengence will be better with strengthening procedure of adducens oculi.
