Question

Glaucoma is a leading cause of blindness in the United States, N. Ehlers measured
the difference in corneal thickness (in microns) between the two eyes of eight patients.
Each patient had one eye that had glaucoma and one eye that was normal. The
difference was measured as the corneal thickness of normal eye – corneal thickness
of eye with Glaucoma. Corneal thickness is important because it can mask an
accurate reading of eye pressure.
