Abstract

PURPOSE
To study the correction effects of standard recession and resection in paralytic strabismus excluding superior oblique palsy. METHODS: Eighteen cases of paralytic strabismus treated by standard recession and resection from March 2005 to October 2007 were retrospectively analyzed. RESULTS: The average angles of deviation before surgery and after surgery were 55 prism diopters (PD) and 12PD, respectively. Adjustable suturing was performed in 12 cases. The diplopia was improved in 14 out of 18 cases (77%) after surgery. Three cases of the -4 grade paralyzed group had a large residual deviation after surgery. The success rate was 78% (14/18) when success was defined as a residual deviation of less than 15PD. Severe ocular motility limitation (-4 grade) group was less affected than other groups. In the below -3 grade paralyzed groups, patients resolved diplopia in the primary eye position, and did not complain of diplopia by incomitance in the secondary eye position. CONCLUSIONS: Standard recession and resection may actively be attempted in below -3 grade paralytic strabismus patients to resolve diplopia in the primary eye position.
