BACKGROUND Classic teaching suggests that surgery for intermittent exotropia should be based on distance/near differences. Divergence excess, according to tradition, should be treated with symmetric lateral rectus recessions; simulated divergence excess and basic deviations should be treated with a recess/resect procedure. This teaching, to our knowledge, has not been systematically tested. O...

Among the types of exotropia in childhood, intermittent exotropia (IXT) has been reported to be the most common type. In a population-based cohort, the prevalence of exotropia has been reported to be 1%, with convergence insufficiency and intermittent exotropia being the commonest of the subtypes. A recent large population-based cohort of 5831 preschool children reports a prevalence of 3.2% of ...

Various ocular and systemic reactions have been associated with insect sting. However, insect stings have been rarely reported to cause exotropia and diplopia. We encountered exotropia in a 6-year-old child with rhabdomyolysis of the left lower extremities caused by an insect sting. Exotropia and diplopia developed within 1 day after the sting and improved completely 1 week after the onset of s...

Intermittent exotropia is more common and tends to develop later in life. When considering the surgical approach to exotropia, an initial overcorrection may result in better long-term motor alignment [10,11]. Specific recommendations for overcorrection of patients with intermittent exotropia vary: Raab and Parks [12] advised overcorrection by 10∆ to 20∆; Scott and colleagues [13], 4∆ to 14∆; Mc...

IMPORTANCE The Intermittent Exotropia Questionnaire (IXTQ) is a patient, proxy, and parental report of quality of life specific to children with intermittent exotropia. We refine the IXTQ using Rasch analysis to improve reliability and validity. OBSERVATION Rasch analysis was performed on responses of 575 patients with intermittent exotropia enrolled from May 15, 2008, through July 24, 2013, ...

PURPOSE To investigate the effect of unilateral medial rectus muscle resection for recurrent exotropia after bilateral lateral rectus muscle recession for intermittent exotropia METHODS A retrospective analysis was made of thirtypatients who underwent unilateral medial rectus resection for recurrent exotropia. All had prior bilateral lateral rectus recession for intermittent exotropia. Data w...

PURPOSE To report a unique surgical approach for congenital double elevator palsy with sensory exotropia. CASE REPORT A 7-year-old boy with congenital double elevator palsy and sensory exotropia was managed surgically by Callahan's procedure with recession and resection of the horizontal recti for exotropia without inferior rectus recession, followed by frontalis sling surgery for congenital ...

Background: This study aims to assess the impact of preoperative deviation on surgical success and sensory function in infantile exotropia. Furthermore, effects late timing these patients.Materials Methods: retrospective evaluated 16 subjects with exotropia that underwent management between 2012 2018. Patients ≤ 50 prism diopters (PD) were added Group 1, > PD 2 function. The is descri-be...
