Maddox rods are used in conjunction with prisms measuring lateral and vertical phoria in both near and distant vision. Maddox rod phoria testing is a suitable alternative to the Von Graefe Phoria technique, and is indicated when a patient is unable to see two targets in the Von Graefe test. The Maddox rod test can be performed in free space without use of the phoropter.
