New Mobile Technologies and Visual Acuity

Livingstone, Iain ;   Tarbert, Claire Margaret

Mobile devices have shown promise in visual assessment. Traditional acuity measurement involves retro-illuminated charts or card-based modalities. Mobile platforms bring potential to improve on both portability and objectivity. The present research activity relates to design and validation of a novel tablet-based infant acuity test. Early results in an adult cohort, with various levels of artificially degraded vision, suggest improved test-retest reliability compared with current standards for infant acuity. Future trials in the pre-school population will assess the value of this emerging technology in pediatric visual screening.
