A 39-year-old woman presented with 48 hours periodic esotropia and hypotropia after vitreoretinal surgery for retinal detachment and then loss of vision in the left eye. The ocular motility revealed the limitation of supraduction and abduction of the left eye on strabismic days and full duction on good days. After strabismic surgery only for correcting esotropia, the patient changed to hypotropia on the previous strabismic days and exotropia on the previous good days alternatively in a 48-hour period. Its pathogenesis is still unknown. We supposed the patient had similar neurological mechanisms as ocular neuromyotonia and secondary cyclic oculomotor palsy.
