Constant Exotropia with Onset Before 6 Months of Age (Infantile Exotropia)

Clinical Scenario

This protocol covers infantile exotropia — a constant exotropia that presents before 6 months of age. It shares characteristics with infantile esotropia, including limited binocular potential, oblique muscle dysfunction, latent nystagmus, and dissociated vertical deviation.

Management Approach

Initial care targets amblyopia when present and addresses clinically significant refractive error. These steps are taken with the aim of supporting fusional control and reducing the angle of deviation. The full structured regimen and sequencing are available via the link below.

Clinical Goals

Improved fusional control and decreased angle of the exodeviation.

Infantile exotropia appears before 6 months of age and is a constant exotropia that has many characteristics similar to infantile esotropia, including limited binocular potential, oblique muscle dysfunction, latent nystagmus, and dissociated vertical deviation.

In children with exotropia, treatment for amblyopia may improve fusional control, decrease the angle of the exodeviation, and thereby improve the postoperative success rate in those requiring strabismus surgery.

In the setting of an exodeviation, corrective lenses should be prescribed for any clinically significant refractive error that causes reduced vision in one or both eyes.
