FACTORS INFLUENCING THE SUCCESSFUL OUTCOME AND RESPONSE IN STRABISMUSSURGERY

In this retrospective study based on 140 esotropic and 51 exotropic pa tients, the factors influencing successful outcome and response to str abismus surgery were investigated, Thirteen independent variables were chosen, The pre-operative deviation was found to be the only discrimi nant factor for early and late successful surgical outcomes in esotrop ic patients, For exotropic patients the visual acuity of the left eye was the discriminant factor for early successful surgical outcome. In esotropic patients the response to surgery increased with increasing a mounts of pre-operative deviation, It was lower for patients with olde r age of onset and larger amounts of medial rectus recession, For exot ropic patients the response to surgery was higher for larger pre-opera tive deviations. Eliminating possible sources of error when determinin g the pre-operative deviation will improve the predictability of the r esponse to surgery and surgical outcome.
