Purpose To determine if the deviation angle changes in subjects with intermittent exotropia as they alternate fixation between the right and left eye in primary gaze. Methods In this prospective observational cohort study, 37 subjects with intermittent exotropia were tested for evidence of incomitance. The position of each eye was recorded with a video tracker during fixation on a small centr...

Abstract Background To evaluate the distribution pattern and changes of strabismus surgery in northern China. Methods The records patients at Qingdao Eye Hospital from January 2014 to December 2019 were reviewed retrospectively. characteristics analyzed included gender, regional distribution, constituent ratio age type strabismus. Changes during periods 2014–2016 2017–2019 compared analyzed. Re...

Background/aims: Racial variation in the pattern of strabismus is known, but few large scale studies on non-white populations are available. Furthermore, longitudinal change in this pattern within a local setting has not been well documented in the past. This study aims to support the clinical impression that exotropia is more common in Chinese patients, and that the proportion of patients with...

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...
