This group will receive treatment with oculomotor therapy

This group will not receive any type of treatment

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.

General mobility will be assessed using the Timed 'Up-and-Go' test with time measured in seconds as the unit of measurement.

The single-leg stance test is used to assess static balance and predict frailty, particularly in community-dwelling older adults. Participants will be asked to stand on one leg for a maximum of 30 seconds, first with eyes open and then with eyes closed. The duration will be measured in three trials per visual condition, and the longest time will be considered. Longer stance duration indicates better balance. The examiner will remain beside the participant to prevent any risk of falling.
