“…Cyclic strabismus is not known to have a mechanism, although biological clocks and diurnal and circadian rhythms may play a role [ 1 , 2 , 11 ]. For cyclic pattern, following theories have been proposed in the literature – aberration of the central nervous system disease [ 2 ], peripheral disease such as traumatic aphakia[3], optic atrophy [ 4 ], strabismus surgery [ 5 , 6 ], high AC/A ratio [ 7 ] and dysthyroid ophthalmopathy [ 8 ]. Children with cyclic strabismus usually begin experiencing it around 3 to 4 years of age without any triggering events.…”

“…A majority of cyclic strabismus cases occur in children [ 1 ] and are idiopathic. It has been reported that adult-onset cyclic strabismus can be associated with central nervous system [ 2 ] and peripheral diseases, such as traumatic aphakia [ 3 ], optic atrophy [ 4 ], strabismus surgery [ 5 , 6 ], high AC/A ratio [ 7 ] and dysthyroid ophthalmopathy [ 8 ], but no case of cyclic strabismus with axial high myopia has been reported. In spite of numerous attempts to explain the pathophysiology of this condition, the exact mechanisms remain unknown.…”

Background It is a very rare form of ocular motility characterized by alternating strabismus and orthotropia. We report a patient with a 48-h cycle of esohypotropia associated with axial high myopia that resolved by Yokoyama procedure. Case presentation A 43-year-old female patient who underwent left medial rectus muscle recession and lateral rectus muscle resection elsewhere due to highly myopic strabismus 2 years ago. The patient experienced a recurrence of left esohypotropia 12 months after undergoing surgery, exhibiting a 48-hour cycle. The cycle is one full day of esohypotropia and one day of orthotropia. The patient exhibited a case of high myopia in the left eye, characterized by a diopter measurement of -24.00DS and an eye axis measurement of 28.43 mm. Orbital CT showed supertemporal dislocation of the posterior portion of the elongated globe out from the muscle cone. Based on these observations, we performed Yokoyama procedure by uniting the muscle bellies of the superior rectus(SR) and lateral rectus (LR) muscles to restoring the dislocated globe back into the muscle cone. Conclusions When cyclic strabismus is combined with axial high myopia, the Yokoyama procedure was effective and cycles are successfully terminated without overcorrection on no squint days. The purpose of this procedure is to put the dislocated globe back into its muscle cone by uniting the muscle bellies of the superior rectus and lateral rectus.

Purpose: To describe two patients with childhood cyclic esotropia 8 and 9 years after they underwent botulinum toxin type A treatment to report its long-term outcome. Methods: Two patients with sudden onset cyclic esotropia aged 2 and 4 years were included. Botulinum toxin type A injections were performed on the appropriate muscles. Results: The first patient was a 2-year-old boy with left dominant alternating esotropia on a cyclic basis. His strabismus ranged from 25 to 45 prism diopters (PD) at near and distance. A botulinum toxin type A injection into the left medial rectus muscle revealed orthotropia at near and distance with a stereopsis of 60 seconds of arc (arcsec). During the 9 years of follow-up, he remained stable. The second patient was a 4-year-old girl who complained of double vision and strabismus. Her deviation was 40 PD at near and 35 PD at distance on a cyclic pattern. She became orthotropic with glasses after a bimedial botulinum toxin A injection. During the 8 years of follow-up, she remained stable with a stereo-acuity of 120 arcsec. Conclusions: Considering the consecutive and recurrent deviations with surgical treatment in previous reports, botulinum toxin type A is an appropriate first-line option for the treatment of cyclic deviations, despite its limitations. The results suggest that botulinum toxin type A is an effective method to break the cycle in cyclic esotropia permanently. [ J Pediatr Ophthalmol Strabismus . 2019;56(6):360–364.]

A case of adult-onset cyclic esotropia combined with hypotropia

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.
