Determination of the Validity of a Questionnaire to Assess the Visual Function of Preverbal Children With Operable Bilateral Ocular Pathologies

In some symmetrical pediatric ocular pathologies, the treatment is surgical with usually satisfactory postoperative results in visual terms.

However, it is often difficult to choose the right moment to operate. The main difficulty is that the child's vision is unknown since the child is still in a preverbal age.

The investigators have developed a questionnaire with the aim of quantifying the child's vision so that the decision is most justified. The items of this questionnaire were established based on the literature and were submitted to a panel of experts in ophthalmo-pediatrics. The objective of this study is to determine the internal validity and as far as possible (since there is no equivalent tool) the external validity of the questionnaire developed.
