Photoscreening to detect potential amblyopia
Abstract
Photoscreening to detect amblyopiogenic conditions is particularly applicable for the child under three years of age because conventional testing is difficult. We have designed an eccentric photoscreener that is inexpensive, easily used and requires only one diagnostic photograph. Some 231 infants and children were refracted and photoscreened and results compared in a blind study. Compliance was good and all cases of strabismus, amblyopia, and amblyopiogenic conditions were diagnosed.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 231 participants or records.
