Abstract Background The treatment efficacy of botulinum toxin bilateral medial rectus injections for acute acquired concomitant esotropia (AACE) in adult is not clear. We characterize the effects injection AACE, especially patients over 14 years old, and compared it with surgical treatment. Methods In this prospective, nonrandomized, controlled clinical study, AACE our hospital from March 2017 ...

This systematic review and meta-analysis is to evaluate the risk of development of concomitant strabismus due to refractive errors. Eligible studies published from 1946 to April 1, 2016 were identified from MEDLINE and EMBASE that evaluated any kinds of refractive errors (myopia, hyperopia, astigmatism and anisometropia) as an independent factor for concomitant exotropia and concomitant esotrop...

Much of the controversy that has arisen in the management of convergence excess esotropia results from differences in definition. A review of the literature reveals a number of studies concerning the management of convergence excess esotropia which are clearly dealing with different, although related, conditions. This makes comparison of outcomes difficult. The major difference in management is...

PURPOSE To elucidate the pathophysiology of dissociated horizontal deviation. METHODS The reversed fixation test was performed prospectively in 28 patients who developed consecutive exotropia following horizontal extraocular muscle surgery for infantile esotropia. All patients were assessed for the presence of adduction weakness, latent nystagmus, dissociated vertical divergence, and neurolog...

The purpose of this comparative study was to evaluate a long-term efficacy of lateral rectus muscle resection in the affected eye of patients with Duane retraction syndrome (DRS) with esotropia and limited abduction and to compare it with bilateral medial rectus recessions. We reviewed and compared the data of the group A with 23 patients who underwent a recession-resection procedure and the gr...

PURPOSE Infantile esotropia is associated with abnormal visual development and thus may delay the achievement of developmental milestones. Although early surgery can improve visual function, less is known about its effect on motor development. Here we address whether early surgery can improve motor development. METHODS Recently, our lab devised the Infant Developmental Skills Survey, a 25-ite...

BACKGROUND To analyze the surgical outcomes for patients diagnosed with acquired nonaccommodative esotropia (ANAET). METHODS In this retrospective study, the medical records of 35 patients who had undergone the surgery for ANAET with a postoperative follow-up period of 6 months or more were reviewed. The main outcome measures were postoperative esodeviation angle, final success rate, and fact...
