Vision therapy vs prism for small-angle eye turn
Part of Brain & nervous system, Eyes & vision clinical trials.
This trial compares two non-surgical treatments—vision therapy exercises and prism glasses—for people with a recent, constant inward eye turn (esotropia) of a small angle. The goal is to see which approach works better to straighten the eyes.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 10 and 40 years old.
- Your eye turn started recently (acute) and is constant (not intermittent).
- The eye turn is small — less than 15 prism diopters.
- You see well in both eyes with glasses or contacts (20/20 or better).
- You have not had any treatment (surgery or prism) for this eye turn before.
- Your eye turn does not improve by more than 10 prism diopters just by wearing glasses.

This study compares two treatments for a sudden, small inward eye turn that starts in adulthood: injecting botulinum toxin (Botox) into the eye muscle versus wearing special prism glasses. The goal is to see which treatment helps straighten the eye and reduce double vision.
This study compares two non-invasive treatments for eye focusing problems: vision exercises combined with gentle electrical brain stimulation versus vision exercises alone. It aims to see if adding brain stimulation improves the ability to focus the eyes better than exercises alone.
This study compares two treatments for esotropia (inward turning of the eyes) in children and teens. One treatment is an injection of botulinum toxin (Botox) into the eye muscle, and the other is traditional eye muscle surgery. The goal is to see which treatment works better for improving eye alignment.
This study tests eye drops to improve how a child’s eyes line up and how well they can use both eyes together. It may help children with certain types of outward eye drifting (intermittent exotropia/exophoria).
This trial tests if a fun, game-based training program can improve vision in children with lazy eye caused by a difference in glasses prescription between the two eyes. It is designed for children ages 4 to 7 who can participate in vision exercises.
This trial tests whether adjusting prism glasses over a shorter time helps people with symptomatic inward eye turn (esophoria) and whether surgery results are better after that adaptation. It may be helpful if you have double vision, eye strain, or headaches that worsen with fatigue or reading.
