Heterophoria Assessment Rods

Definition : Ophthalmic rods designed to detect the misalignment of the eyes (heterophoria). The devices may consist of a glass rod or several parallel cylindrical glass rods attached together; when a rod is placed in front of the eye under test a distant dot of light appears as a line. The person with heterophoria will see a point of light at one side of the line of light, while the person with normal vision will see the line passing through the point. The amount of deviation can be measured by using different diopter prisms put in front of the test eye. Heterophoria assessment rods (known as Maddox rods) are used mainly to detect heterophoria.
