A computerized screening devicedesignedto detect refractive abnormalities in vision , such as nearsightedness , farsightedness , and astigmatism
the irregularitiescauserefractive error and visual problems like nearsightedness , farsightedness and astigmatism
Periocular IHsmay resultin astigmatism , refractive errors , strabismus , leading to amblyopia and visual impairment
screening testscan leadto detection of amblyopia , strabismus and refractive errors
strabismus ( ocular motility disorders correctable than not diagnosed in timecan causedecreased visual acuity and even blindness ) and refractive disorders ( farsightedness , nearsightedness and astigmatism
However , screening this population has been problematicleadingto under detection of significant refractive error and strabismus ( squint
Similar to keratoconus , it is characterized by progressive thinning and steepening of the cornearesultingin corneal optical irregularities and loss of visual acuity
