Vision therapy for convergence insufficiency after concussion
Part of Brain & nervous system, Eyes & vision, Injuries & trauma clinical trials.
This study looks at how convergence insufficiency (a problem where your eyes don't work together when looking at things close up) develops after a concussion, and tests whether a special vision training program (vision therapy) can improve it. If it works, it might help you recover your visual comfort and reduce symptoms like eyestrain and headaches.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 18 and 35 years old.
- You must have had a mild traumatic brain injury (concussion) more than 1 month ago but less than 6 months ago.
- You must have symptoms of convergence insufficiency (trouble with close-up vision, eye strain, headaches) that score at least 21 on a standard symptom checklist.
- Your eyesight (with glasses or contacts if you wear them) must be at least 20/25 at both near and far distances.
- You must have specific eye teaming problems — your eyes don't turn inward enough for close-up work, and you have a reduced ability to maintain clear focus.
- You must not have had prior treatment for convergence insufficiency or been diagnosed with it before.

This study tests a home-based eye exercise program for people with mild traumatic brain injury who have ongoing vision problems like blurring or trouble focusing. It aims to help your eyes work together better and reduce symptoms.
This trial tests if a 12-week home-based vision therapy program can improve double vision and reading issues in veterans with traumatic brain injury. It targets a specific problem called convergence insufficiency, where the eyes don't work together when looking at close objects.
This study tests a noninvasive brain stimulation treatment to improve symptoms of convergence insufficiency, a condition that makes near vision tasks like reading harder. You may be randomly assigned to the study treatment or a comparison condition.
This trial tests whether a special type of eye exercise can help people with convergence insufficiency, a condition where your eyes struggle to work together when looking at close objects. Participating could improve your eye coordination and reduce symptoms like eyestrain or double vision.
This study tests whether adding osteopathy (a hands-on therapy for muscles and joints) to standard eye exercises helps people who have eye strain from computer work. If you spend long hours at a screen and have eye discomfort, it might improve your symptoms.
This study tests whether adding special balance and eye exercises to standard physical therapy helps athletes recover from post-concussion syndrome. If you've had a concussion recently and still have symptoms like dizziness or headaches, this treatment might help you get back to normal faster.
