Abstract

Abstract: : Purpose: To investigate the treatment effect of A-pattern strabismus by weakening procedures of superior oblique muscle. Methods: The clinical features and types of surgeries of 35 cases of A-pattern strabismus admitted in the Department of Strabismus in Zhongshan Ophthalmic Center were analyzed. 17 patients were males,18 cases were females, aged from 5-15 years, average 21 years. Results: 69 eyes of 34 cases had SOOA. 60 eyes of 30 cases have undergone bilateral weakening procedure of SO, 4 cases unilateral weakening procedure of SO. 64 eyes of 34 cases had normal action of SO after surgery. A-pattern in all 35 cases disappeared, 31 cases(88.6%) had normal alignment (horizontal strabismus less than 5 degrees). Conclusion: The SOOA is the main feature of A-pattern strabismus. Weakening procedure of SO is important to correct the A-pattern strabismus. The horizontal deviation can be corrected by the procedure of medial or lateral rectus muscle.
