Cyclic esotropia is a rare and poorly understood condition normally treated by correcting the deviation measured on the squinting day. Control in some patients with this condition can be gained by correcting their refractive errors, thereby improving acuity. We report on an adult patient who developed cyclic esotropia after unilateral traumatic aphakia with failed contact lens wear whose squint was corrected by secondary intraocular lens implantation. This may be explained by the reduction in the degree of aneisokonia which subsequently improved steropsis.

Various forms of cyclic strabismus have been described. A cyclic variation in binocular function modifying a tendency to strabismus is said to be the underlying mechanism. Cyclic esotropia developed in two adult patients, one having no demonstrable binocular function and the other having suffered complete unilateral visual loss in the affected eye. In each case, on the "good days" there was still a manifest esotropia, in contrast to those patients with cyclic esotropia and good binocular function in which the eyes are straight on the "good days." The presence of binocular function is not required for the development of cyclic strabismus, although the level of binocular function is correlated with the ocular alignment on the "good days."

Cyclic esotropia is a rare phenomenon in which esotropia and orthophoria alternate over a period of 48 to 96 hours. The mechanism that underlies the phenomenon is unknown. Cyclic esotropia often occurs after a fusion-disrupting event. We report an unusual case of cycling esotropia with onset after a traumatic sixth nerve palsy. The cyclic phase persisted for 2 years, following a 48-hour alternate-day pattern. After strabismus surgery for the esotropic angle, the deviation disappeared and the patient remained orthotropic, with 1 year of follow-up to date.

Cyclic esotropia is a rare form of strabismus in which a convergent squint appears and disappears typically, but not always, in a regular 48-hour cycle. Characteristically, the convergent squint, when present, has a large angle with associated suppression and no binocular function. On normal or "nonsquinting" days, no manifest deviation is detectable (although in some cases there may be an esophoria). Physiologic diplopia is appreciated, whereas fusion and stereopsis are all normal. Amblyopia may occur in up to 20% of cases.

Cyclic esotropia is a rare condition in which esotropia alternates with binocular single vision (BSV). A five years old female child presented with the complain of acute onset infrequent squinting of left eye (L/E) for 3 years. Squinting of L/E starts in morning and persists throughout the day. The child becomes completely normal on the following morning without any residual effect. Initially there was 24 hours squinting followed by several months of non-squinting. Gradually interval is lessening. For the last 6 months, she was esotropic for 24 hours and non-esotropic for another 24 hours. She complains of no diplopia during the attack. On examination she is otherwise healthy and hypermetropic by +0.50Dsph on cycloplegic refraction with normal visual acuity (6/6, N5). She was 50 prism diopter esotropic in her left eye on esotropic day both for distant and near fixation and had alternate suppression. Ocular motility is full. Anterior and posterior segment reveals no abnormality. There is BSV with positive stereoscopic vision on Titmus test (40 sec of Arc) on non-esotropic day. This case can be treated surgically either by bilateral medial rectus recession or by recession of medial rectus and resection of lateral rectus of the eye according to the amount of esotropia on the esotropic day.

Cyclic esotropia, characterized by alternating intervals of esotropia and orthotropia, is associated with decreased vision, trauma, strabismus surgery, or central nervous system disease. We report a 6-year-old boy who developed cyclic esotropia after 3 years of successful control of accommodative esotropia with full hyperopic correction. After bilateral medial rectus recession, he remained esophoric with good binocular function and stereoacuity. To our knowledge, this is the first report of accommodative esotropia decompensating into a cyclic esotropia.

Cyclic esotropia is a rare entity in which an esotropia presents in a regular 48-96 hour cycle, typically described as a 24-hour period of orthotropia followed by a 24-hour period of esotropia. The underlying mechanism of this phenomenon is unknown. Treatment usually involves surgical correction of the manifest strabismus. We report the case of a 3-year-old girl whose cyclic esotropia was broken following injection of botulinum toxin to both medial rectus muscles. She has remained constantly esophoric for 1 year.

Cyclic esotropia is characterized by a 24-hour period of straight eye position followed by 24 hours of large-angle esotropia. Possible mechanisms include notably progressive loss of compensation of a latent strabismus. The classic treatment is surgical correction of the angle measured on the days with manifest deviation. We report the first case of cyclic esotropia successfully treated by prismatic correction of the latent strabismus present on "straight" days.

Cyclic esotropia is an extremely uncommon form of strabismus. Classically, it follows a 48-hour cycle with 24 hours of orthotropia and 24 hours of manifest esotropia. We are reporting the first case of cyclic esotropia with a 24-hour cycle. A 7-year-old hyperopic female was seen with an esotropia of 6-month duration. Hyperopic glasses were prescribed by another ophthalmologist prior to our evaluation of the patient. While wearing her glasses, esotropia occurred during the morning and early afternoon. After 3.00pm, her eyes were "straight." Many photographs were reviewed, confirming the esotropia pattern. Neurological evaluation was normal, including imaging and blood work to rule out thyroid pathology and myasthenia. After seeing the patient multiple times at different hours on different days, the diagnosis of cyclic esotropia was made. Bimedial recessions were performed with good results. The patient was still "straight" at distance and near 2 years after surgery.
