Abstract

Intermittent exotropia is the most common type of exodeviations. It can be categorized into3 types depending on the disparity between distance and near deviation in prism diopters; distance, near, or basic. Each type has a different approach. The treatment is mainly surgically, however, in most cases, exotropia recurs after surgical treatment to cause what we call postoperative drift. Although a notable correlation between age and postoperative drift has been identified, it remains unclear why it causes such outcomes in larger age groups. Multiple factors lead to this outcome, some have more influence than others. In this study, we aimed to assess those factors in early teenagers and older individuals as it is more frequent in these groups. We assessed the relationship between different factors other than age such as preoperative deviation, and intraoperative millimeters of muscle movement and their significance in postoperative drift.

Aim of work:
This study aims to report the outcome and drift tendency after surgery after a 4-6 month ‘period and the need for another surgery in cases of large angle decompensated exotropia.
