Strabismus is a condition where one eye looks at the object of interest, while the other eye looks in a different direction. Esotropia is a specific form of strabismus where one eye turns toward the nose. With the abundance of smart phone use, especially for videos, can lead to long periods of keeping the phone close to the face, putting a lot of stress on the extrinsic muscles of the eye. In this episode, I speak to a young woman whose smartphone use led to esotropia, which had to be corrected with surgery. In addition to being a cautionary tale about smartphone overuse, we have a fascinating discussion of the symptoms and correction of esotropia. Enjoy!
