Photoscreening for amblyogenic risk factors in 1-year-olds: results from a single center in Portugal over a 9-year period

The rate of unreadable screenings was low. The overall PPV was lower than other large studies, at older ages, but higher than those of the same-age children. Considering the potential benefits of early intervention in preventing the development of amblyopia, this study demonstrates the feasibility of screening 1-year-olds.
