Abstract
The angle kappa is defined as the angle between the optical axis and the visual axis. A positive angle kappa may simulate an exodeviation, while a negative angle kappa may simulate an esodeviation. It is measured by several methods, and ranges from 2 to 5 degrees. A 19 year old Korean male was seen in our clinic complaining of exodeviation OS, but he was found to have an esotropia OD with large positive angle kappa.
