Predictors of Recurrence After the Surgical Correction of Exodeviation
MetadataShow full item record
Exodeviations are outward misalignments of the eyes, that may be characterized by periods of control and binocular vision. Despite the frequency of this diagnosis, treatment outcomes remain inconsistent. Surgery is one treatment option that can be pursued. Pre-operative assessment outcomes have been associated with surgical success, including stereopsis, angle of deviation, and refractive error. The variability in preoperative management and surgical planning between subjects may contribute to poor surgical outcomes in this patient population. This study seeks to determine how many surgically corrected subjects with exodeviations have favourable outcomes, if there are measurable predictors for unsuccessful surgical outcomes on orthoptic examination, either pre or post-operatively, or whether there is a relationship between the personalization of recommended surgical doses and surgical outcomes. A success rate of 43% was determined, and associated with Duane’s classification, angle of deviation, visual acuity in the left eye, and follow up period.
