Many children with accommodative esotropia are able to successfully discontinue spectacle wear, while others require spectacle correction into adulthood. Parents often ask about the likelihood of glasses being required on a long-term basis and whether use of spectacles will cause dependency. Most infants are hyperopic and gradually become emmetropic. The extent to which accommodation and specta...

A standard set of clinical prism and cover tests and a recently developed photographic method were used to assess binocular alignment in ten monkeys that previously were determined to have a naturally occurring infantile strabismus. Extensive measurements of the alignment state were made for fixation attempts throughout the field of gaze. Patterns of alignment errors were examined in an attempt...

PURPOSE To evaluate the anterior segment biometric parameters of non-accommodative and accommodative refractive accommodative esotropia (RAE). METHODS Eighty-one eyes of 81 patients were included in this prospective, case-control study. The patients were divided into three groups as follows: the RAE group (n = 31), the hypermetropia group (n = 25), and the emmetropia group (n = 25). Measureme...

PURPOSE To investigate horizontal image disparity in three-dimensional (3-D) perception using 3-D animations in normal control patients and patients with intermittent exotropia, anisometropic amblyopia, and partially accommodative esotropia. MATERIALS AND METHODS A total of 133 subjects were included. Stereopsis was measured using the Titmus Stereo test (Stereo Optical Inc., Chicago, IL, USA)...

PURPOSE The aims of this study were to examine the distribution of refractive errors and clinical characteristics of strabismus in Korean patients with Down's syndrome. METHODS A total of 41 Korean patients with Down's syndrome were screened for strabismus and refractive errors in 2009. RESULTS A total of 41 patients with an average age of 11.9 years (range, 2 to 36 years) were screened. Ei...

PURPOSE To propose an alternative and practical model to conceptualize clinical patterns of concomitant intermittent strabismus, heterophoria, and convergence and accommodation anomalies. METHODS Despite identical ratios, there can be a disparity- or blur-biased "style" in three hypothetical scenarios: normal; high ratio of accommodative convergence to accommodation (AC/A) and low ratio of co...
