PURPOSE The purpose of the present study is to evaluate the therapeutic effects of slanting muscle insertions for "A" and "V" exotropia. METHODS We performed slanting recession and resection of medial or lateral rectus muscles. A slanting surgical incision creating a 3-4 mm difference between the upper and lower margins of the muscles was performed in 28 patients with "A" or "V" exotropia ( "...

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 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...

AIM To assess the consecutive recurrence following early success of intermittent exotropia surgery and to determine the clinical factors that affect the survival. METHODS One hundred and thirty-five patients who underwent intermittent exotropia surgery and experienced early surgical success [≤5 prism diopters (PD) esophoria (E) to ≤10 PD exophoria (X) on the postoperative sixth month] were en...

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...
