Effect of Binocular Treatment Using a Dichoptic Reading Application in Children With Convergence Insufficiency.

"Intervention 25 min/day, 5 days a week for 6 weeks at home (125-minute weekly load), under the supervision of a parent, on a dichoptic reading application on a loaned digital tablet, wearing anaglyph glasses provided and the patient's optical correction (if applicable).~During the first half of treatment (first 3 weeks), dichoptic separation takes place at the word level, and during the second half of treatment (last 3 weeks), it takes place at the individual letter level to promote precise eye alignment. This shift from dichoptic separation at word level to letter level increases the difficulty of the task. The text is freely chosen by the child and parent from a bank of age-appropriate books."

Conventional orthoptic rehabilitation consisting of 12 x 25-minute sessions twice a week over 6 weeks, carried out with an orthoptist from Montpellier University Hospital, combined with reinforcement exercises to be carried out at home for 15 minutes a day under parental supervision, 5 days a week (125-minute weekly load). This is the standard orthoptic treatment offered in France to patients with symptomatic convergence insufficiency, according to orthoptic procedures (10-15 sessions of the order of 20-25 minutes and 10-15 minutes of daily reinforcement exercises at home).
