Animation for Amblyopia

A child with amblyopia uses special glasses to view a dichoptic film.

Many ophthalmologists are familiar with the concept of patching a child’s eye to treat amblyopia by forcing the brain to use the weaker eye. Some may even have experienced patching themselves. But this kind of treatment means that the dominant eye remains unused and the two eyes don’t work together. Researchers are now looking into more modern ways of treating the condition, including video games (1) – and now, a special type of movie.

Dichoptic therapy uses both eyes at the same time. In the case of the movies, viewers wear special glasses that partially block the images presented to each eye, so that one eye “fills in the blanks” for the other. Additionally, the images sent to the dominant eye have reduced contrast to balance out image suppression in the weaker eye due to binocular dysfunction – meaning that children use binocular vision to see a complete picture.

About the Author

Michael Schubert

While obtaining degrees in biology from the University of Alberta and biochemistry from Penn State College of Medicine, I worked as a freelance science and medical writer. I was able to hone my skills in research, presentation and scientific writing by assembling grants and journal articles, speaking at international conferences, and consulting on topics ranging from medical education to comic book science. As much as I’ve enjoyed designing new bacteria and plausible superheroes, though, I’m more pleased than ever to be at Texere, using my writing and editing skills to create great content for a professional audience.
