Angle deviation changes in early and late postoperatory following strabismus surgery

The aim of this study is to evaluate the angle changes and evolution in the postoperatory time and to establish the relationships between them. 146 patients, (medium age 14.17 +/- 15.73 sd), 80 cases of esotropy (ET, range +70(Delta) to +14(Delta)), 48 of vertical deviation (VD, range 25(Delta) to 12(Delta)), and 18 of exotropy (XT, range -70(Delta) to -12(Delta)), underwent strabismus surgery. All patients were evaluated prospectively at I week, 2 and 6 months following surgery. Overall patients presented a variation of angle deviation during the follow up, which calculated with the Anova variance test was significant (p<0.05). The relationship between the mean angle value at I week and the mean angle value at 6(th) month was significant (p<0.05). In our experience, the significant variation within 6 months shows the need of a longer period for final surgical outcomes and for further squint surgery.
