Abstract

The cornea is birefringent, and the birefringence can be easily observed in a living eye. For observation, a reflection polariscope is used, the iris serving as a reflector. Some sick people have grossly different and easily identifiable photoelastic patterns from the patterns observed in healthy subjects. The possibilities of a new clinical diagnostic method through the use of photoelasticity is discussed.
