Pioneer Maddox Rod & Occluder

Features: 

• 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.
