Maddox Rod and Occluder - 
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.
 Occluder is molded from strong, lightweight ABS plastic, with an easy cleaning gloss finish. Occluders are used to cover one eye during testing or treatment. Occluders are cupped to a 70mm radius.
