摘要：
Disclosed is a periscopic device for examining an eye of a person with an inwardly squinting eye (esotropia). The periscopic device includes a tube with two mirrors arranged at opposite ends of the tube. The mirrors are arranged so that when the person looks through the periscopic device with the inwardly squinting eye, the two mirrors deflect the line of sight of the person toward an object reflected in the second mirror. To account for the squint of the eye, either a base out prism can be used to deflect the line of sight toward the first mirror, or the two mirrors can be arranged non-parallel to each other. With the inwardly squinting eye focused on the reflected object, the other eye can be examined. Methods of using the periscopic device are also disclosed.
