Summary

The aim of this study is to investigate the effect of oculomotor therapy in individuals with ocular convergence insufficiency.

Conditions

  • Convergence Insufficiency

Interventions

OTHER

Oculomotor therapy

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.

OTHER

No Treatment Added

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
