What advantages does the PhotoScreener have over other vision testing methods?
Most current vision screening methodologies are not effective in screening preverbal children. With the PhotoScreener, however, doctors can reliably screen children as young as six months for conditions that could lead to amblyopia. The methodology is extremely simple: a flash photograph of the subject’s eye is taken. The light reflected from the retina is analyzed to detect refractive errors, strabismus and/or media opacities.
