Mohney BG, et al. - Researchers conducted the study for reporting the prevalence of subclinical markers of strabismus from a community-based screening of children. Family history and ophthalmic examination (including six markers of strabismus: oblique muscle dysfunction, stereopsis < 60 arcsec, monofixation, nasal-temporal pursuit asymmetry, dissociated strabismus, and anisometropia) were collected from consecutive children, aged 5 to 18 years, in the local school system and the pediatric outpatient clinic of Mayo Clinic, Rochester, Minnesota. In total, 1,000 children (498 males [49.8%]) were examined at a mean age of 10.6 years (range, 5-18.98). Subclinical binocular vision disorders occurred in 10%-13% of children without strabismus in this community-based screening, with inferior oblique muscle dysfunction, anisometropia, and subnormal stereopsis being the most common.
