Purpose: To determine the prevalence of amblyopia and strabismus in the schoolchildren of the city of Bojnourd, Iran Methods: In 2010, randomized stratified cluster sampling was employed in a cross-sectional study on primary and junior high schoolchildren. All the examinations were performed in schools. All students received refraction, vision and subjective refraction tests. The cover test was...

purpose : to evaluate outcome of surgically slanting extraocular muscle insertions in a and v-pattern strabismus methods : in this prospective non-randomized interventional case series, we created a slanting surgical reinsertion line with a 3- 4 mm difference between upper and lower corners of the muscles in 16 patients with a or v strabismus (v-exotropia in 10 patients, a-exotropia in 1 patien...

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...

OBJECTIVES To determine the prevalence of and contributing factors for errors in strabismus surgery. METHODS Five hundred seventeen of 1103 strabismus surgeons (46.87%) completed a survey administered during the 2011 American Association for Pediatric Ophthalmology and Strabismus national meeting or e-mailed to members of the association. RESULTS One hundred seventy-three strabismus surgeon...

Purpose. To evaluate the distribution pattern and changes of strabismus surgery in children based on the data collected from a local eye hospital in the south of China between 2006 and 2011. Methods. A retrospective analysis of all strabismus surgeries in children (<18 years) performed in the Eye Hospital of Wenzhou Medical University between 2006 and 2011 using the integrated information syste...

English surgeon John Taylor attempted to perform strabismus surgery in the 18th century. The field languished until, in Germany, treatment of strabismus by cutting an extraocular muscle was proposed by Louis Stromeyer in 1838 and performed by Johann Friedrich Dieffenbach in 1839. According to traditional teaching, there has never been any proof that anyone in the United States thought of the id...

PURPOSE To evaluate the effect of strabismus surgery on proptosis in patients with thyroid-associated orbitopathy. METHODS The medical records of 22 consecutive patients with thyroid-associated orbitopathy undergoing strabismus surgery were reviewed. Data pertaining to the number of muscles operated on, amount of muscle recession, prior orbital decompression, and exophthalmometry were evaluat...

To examine the link between binocular vision and binocular coordination of saccades we studied subjects with convergent strabismus since childhood with mild or no amblyopia: three subjects had small squint (< 10 prism D) and preserved peripheral binocular visual function with gross stereopsis; four subjects had larger squint (18-35 prism D) and no detectable stereopsis. A standard paradigm was ...

PURPOSE Comitant strabismus is a common pediatric ophthalmic disorder with both genetic and non-genetic factors contributing to its etiology. The aim of the current study is to investigate the phenomenon of a parent-of-origin effect, genomic imprinting, as a possible mode of inheritance in comitant strabismus. METHODS We performed parametric genome-wide MOD score (model-maximized LOD score) l...

PURPOSE The aim of this study was to look for the response to strabismus images in the limbic network (amygdala, hippocampus, parahippocampus) of healthy volunteers and to compare it with their reaction to viewing normal eyes. DESIGN Prospective, observational study. PARTICIPANTS Thirty-one healthy volunteers underwent functional magnetic resonance imaging (fMRI). METHODS Functional magne...
