Myopathic, Restrictive, Orbital, and Other Causes of Diplopia
Refractive Procedure–Induced Diplopia
In patients with childhood strabismus, diplopia may be induced by refractive procedures that cause a change in fixation preference to the nondominant eye (eg, monovision correction, cataract surgery on an amblyopic eye prior to the dominant eye, or noncycloplegic refraction leading to undercorrected hyperopia and fixation with the amblyopic eye). “Fixation switch diplopia” resolves with appropriate optical correction to reestablish fixation with the dominant eye.
