Interventions

  • Oculomotor therapy — OTHER
    Oculomotor therapy will follow and adapt the protocol for treating convergence insufficiency (CI). Procedures will be organized progressively, from easiest to most difficult. Gross convergence techniques: (1) Brock String: A 1.5-2 m cord with colored beads; the patient focuses on each bead to train binocular fusion, observing the "X" shape of the cord. (2) Barillé Chart: A card with paired images for each eye; the patient merges the images into one using convergence and sensory fusion. Accommodative techniques: (1) Eccentric Circles: Printed circles with eccentric marks; viewed through filters to train motor and sensory fusion by aligning them into a single 3D image. (2) Opaque Lifesaver Cards: Cards with figures on an opaque background, used with red-green filters to stimulate convergence and fixation by reducing peripheral stimuli and enhancing visual attention.
  • No Treatment Added — OTHER
    Participants in the control group will not receive any type of treatment for a period of five weeks. After this period, they will be re-evaluated
