What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looked at how the brain controls eye movements in people aged 11 to 35 who had a concussion 1 to 6 months ago and still have trouble focusing their eyes (convergence insufficiency). Researchers compared these participants to others with eye focusing problems not caused by concussion, and tested two different lengths of vision therapy. The goal was to understand the brain mechanisms behind the condition and find the best treatment duration.

Inclusion Criteria: * Between 11 to 35 years * Concussion diagnosed by a clinical 1 to 6 months ago * Best-corrected visual acuity of 20/25 in both eyes at distance and near * willing to wear glasses or contact to correct refractive error if needed * Global stereopsis of 500 sec of arc or better and 70 sec of arc of better using Randot Stereo Test * Diagnosis of convergence insufficiency from an optometrist defined as near point of convergence of greater than or equal to 6 cm, positive fusional vergence at 40 cm not meeting Sheard's criteria of at least twice the near phoria or a range of less than or equal to 15 prism diopters, and a convergence insufficiency symptom survey score of 21 or greater for adults or 16 or greater for children. Exclusion Criteria: * History of performing office or home-based vision therapy, orthoptics, home-based near target push-ups, or pencil push ups * Amblyopia (lazy eye) or constant strabismus or strabismus surgery * Any conditions or diseases that affect accommodation, vergence or ocular motility, such as Multiple Sclerosis, Graves' thyroid disease, Myastheria Gravis, Diabetes, Chemotherapy, or Parkinson's Disease * Non-removable metal in the body * Pregnant, planning on becoming pregnant during the study duration, or breastfeeding * Metal worker
