Patients with acquired strabismus have fusion potential that diminishes in proportion to the duration of the esotropia. Early intervention can result in restoration of high grade binocular fusion.
Prompt dispensing of hypermetropic spectacle correction reduces the occurrence of amblyopia and increases the likelihood that spectacles alone will correct the esotropia, obviating the need for surgery.
Acquired esotropia can be a presenting sign of a neurological process such as myasthenia gravis, chronic progressive external ophthalmoplegia (CPEO), Arnold-Chiari malformation, or an intracranial tumor causing a sixth nerve paresis.
