The results of squint surgery in 42 children with primary, non-paralyt ic, childhood exotropia are analysed. A 'favourable outcome', defined as a final alignment for near and distance within +/- 10 dioptres of s traight, or within +/- 20 dioptres of straight with evidence of binocu lar single vision, was achieved in 39 (93%) children. The factors affe cting the final outcome are discussed, including age of onset, age at the time of surgery, preoperative and post-operative amblyopia, refrac tive error, anisometropia, the surgical procedures used, and postopera tive ocular alignment.
