Surgical management of basic -type intermittent exotropia with a dominant eye is controversial. Some surgeons do traditional symmetrical bilateral lateral rectus recession, while other perform unilateral recess-resect procedure in the non-dominant eye. The aim of this study is to investigate the effect of two different strategies of bilateral lateral rectus recession; symmetrical recession in which the amount of recession is equally divided between both eyes, and asymmetrical recession, in which the amount of recession is 2mm more in the non-dominant. Outcome measures include ocular deviation at distant and near fixation, sensory status and complications.
The study aims to investigate ocular motor and sensory outcomes of two different strategies of lateral rectus recession; symmetric and asymmetric, in management of basic type intermittent exotropia with ocular dominance.
