Advances in vision and eye screening: screening at six months of age.
Eye and vision screening is a prototype preventative health measure. Increased knowledge of eye diseases in children and their treatment mandates much earlier screening than was recommended in the past. Advances in testing permit both the adoption of simpler and faster routine techniques and the application of more sophisticated and accurate screening methods. A thorough vision/eye screening at 6 months of age has been added to the previous examination schedule which only required screening at birth and again at 3.5-4 years of age. The simple scrutiny of the red fundus reflexes in the pupil with a direct ophthalmoscope (Brückner test) provides superior screening for vision, binocular alignment and pathology in infants. The difficult-to-master cover test and its variants can be abandoned for screening purposes. In screening preverbal children, simple optotype charts (HOTV) are proving more efficient than the traditional 'tumbling E' game. Color vision testing should be added to the preschool examination. Vision screening in infants can be enhanced where resources permit by using new preferential looking tests and by employing sophisticated electrophysiological testing. Photographic screening methods based on the red reflex hold considerable promise for more efficient screening of children.
