Comparing vision therapy and prism treatment for small-angle esotropia
Official title: Accommodation and Vergence Exercises Versus Prism Treatment for Small-angle Acute Acquired Concomitant Esotropia
Run by Eye & ENT Hospital of Fudan University · NCT06622044 · Data updated 2026-11-12
This study is testing whether vision therapy or prism treatment works better for people aged 10 to 40 with small-angle esotropia to help improve their eye alignment and reduce double vision.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are individuals aged 10 to 40 years with a best-corrected visual acuity of 20/20 and a deviation angle of less than 15 prism diopters.
✕Probably not a fit
Patients with organic eye diseases, brain lesions, or those who have previously received esotropia therapy may not benefit from this study.

What this trial studies
This clinical trial aims to compare the effectiveness of vision therapy versus prism treatment in patients with small-angle acute acquired concomitant esotropia. It is a single-center, randomized controlled trial that focuses on patients aged 10 to 40 years with a deviation angle of less than 15 prism diopters. The study will evaluate how well each treatment alleviates symptoms such as diplopia and improves eye alignment. The trial is particularly relevant given the rising incidence of esotropia associated with increased screen time.
Why it matters
Potential benefit: If successful, this study could provide a non-surgical treatment option for patients suffering from small-angle acute acquired concomitant esotropia.
How similar studies have gone: Other studies have explored treatments for esotropia, but this specific comparison of vision therapy and prism treatment is relatively novel.
