Cyclic esotropia

Xi Wang, Bingjie Chen, Longqian Liu
PURPOSE: To report a patient with cyclic esotropia with a high accommodative convergence to accommodation (AC/A) ratio after surgical correction of intermittent exotropia who was found to have bilateral anomalous medial rectus muscle insertion sites. METHOD: A 5-year-old girl developed intermittent esotropia on alternating days after undergoing bilateral lateral rectus recessions for correction of intermittent exotropia. Alternate prism and cover measurement of ocular alignment and binocular function was assessed on consecutive days...

Cyclic strabismus is a rare condition that usually occurs in children and is characterized by alternating intervals of straight and strabismic eyes. In adults with the condition, strabismus surgery often eliminates the cycles. We report a case of adult-onset cyclic esotropia that was converted into a cyclic exotropia.

PURPOSE: To identify characteristics of pediatric patients who develop acute acquired comitant esotropia (AACE) with and without intracranial disease. METHODS: We reviewed the charts of 48 children consecutively referred to the hospital with AACE during a 13-year period. Inclusion criteria were acute onset of comitant esotropia, available data on ophthalmologic, orthoptic and neurologic examinations. Children with neurological signs, AACE recurrence or hyperopia <+3 dioptres (D) underwent brain computed tomography or magnetic resonance imaging...

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 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, 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...

PURPOSE: This case report presents the diagnosis and management of an adult patient with cyclic esotropia, a rare and poorly understood form of strabismus, that is characterized by alternating periods of manifest strabismus and orthotropia. Few cases of adult-onset cyclic strabismus have been reported. The etiology, pathogenesis, and treatment for this condition are reviewed. CASE REPORT: A 37-year-old man with high unilateral myopia and anisometropic amblyopia in his left eye developed cyclic esotropia 2 months after a scleral buckle procedure for a retinal detachment...

PURPOSE: To identify strabismus-related proteins, we performed proteome analysis in monozygotic twins with discordance of congenital esotropic phenotypes and in normal children. METHODS: Surface-enhanced laser desorption/ ionization time-of-flight mass spectrometry (SELDI-TOF-MS) technology was used to detect changes in protein expression in a pair of twins with discordant esotropic phenotypes (twin A is orthotropic and twin B is esotropic). In addition, two non-twin esotropic children and two orthotropic children of the same age were chosen...

Cyclic strabismus is an uncommon disorder in which strabismus alternates with orthotropia in alternating 24-hour periods, although cycles of other lengths have also been described. Alternate-day exotropia is a rare form of cyclic strabismus which, to date, has been reported in few patients. We describe a case of alternate-day exotropia in a child who had previously undergone surgical correction of constant esotropia.

INTRODUCTION: Cyclic esotropia is a rare form of strabismus consisting of regular intervals of esotropia alternating with periods of orthophoria in a rhythmic/cyclic manner. In the vast majority of cases, surgery appears to permanently correct the esotropia, with no sequelae after years of follow-up. We report a case of consecutive exotropia in a patient five years after bilateral medial rectus recessions for cyclic esotropia. METHODS: A case report involving review of a clinical chart...

Cyclic exotropia, a very rare condition, consists of periods of exotropia and orthotropia alternating on a regular, most commonly 48-hour, cycle. Cyclic vertical deviations, including cyclic oculomotor nerve palsy, also are extremely uncommon. Cyclic esotropia, which is more common than cyclic exotropia, has been reported to occur more frequently in children than adults. We describe an adult patient who developed cyclic exotropia and hypotropia associated with monocular loss of vision.

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...

Cyclic esotropia--periods of esotropia alternating with periods of orthotropia, most commonly on a 48-hour cycle--is a rare condition seen mostly in children. Surgical correction of the maximum deviation generally corrects the esotropia without resulting in alternating periods of exotropia, as might be expected if the periodicity continued postoperatively. Unlike cyclic esotropia in children, the few reported adult cases have often been associated with severe acquired monocular visual impairment; however, the response to surgical treatment is reported to be the same as that in children...

BACKGROUND: Cyclic strabismus, which generally has a 24 hours on-off cycle, is an unusual but interesting form of ocular motor disorder. Cyclic deviations are characterized by periods of significant deviation followed by periods of strict orthotropia. In the orthotropic periods, binocular sensoriality and motricity are normal. During the symptomatic phase, in which the deviation is usually significant and permanent, certain sensory anomalies can be found. Although most referred cases are cyclic esotropia, other cyclic oculomotor disorders have been described...

A young girl had cyclic esotropia with cyclic inferior oblique overaction and "V" pattern. A recession-resection surgery of the horizontal rectus muscles and recession of the inferior oblique muscles cured the cyclic esotropia as well as the inferior oblique overaction and V pattern.

PURPOSE: To describe the characteristics and significance of acquired oculomotor nerve paresis with cyclic spasm. METHOD: Retrospective case series of two patients with a history of previous skull base irradiation for intracranial tumor who developed double vision and were found to have oculomotor nerve paresis with cyclic spasm. Both patients underwent a complete neuroophthalmologic assessment, including testing of eyelid position, pupillary size and reactivity, and ocular motility and alignment during both the paretic and spastic phases of the condition...

AIM: To describe the development and treatment of V-pattern and bilateral over-elevation in adduction in patients with cyclic esotropia. METHODS: Three patients with cyclic esotropia are described in retrospect. All patients underwent bilateral medial recession, while one patient additionally had a weakening procedure of both inferior oblique muscles. RESULTS: All patients developed a V-pattern and bilateral over-elevation in adduction. After strabismus surgery, normal eye alignment with some signs of binocularity was reached in all three patients...

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 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...
