POST-BV RECAP

What is an advantage of the Maddox Wing test?

• Can quantify the deviation

• Require additional instruments (pen torch and prism bar)

• Require dark room

• Require subjective response

What is a disadvantage of Cover Test?

• Require subjective response

• Can quantify the deviation

• Require dark room

• unable to detect the direction of deviation

How is dissociation achieved in the Maddox Rod test?

• distorts the image into a thin streak

• Disrort the Septum

• Dissociate the image using prism

• Dissociate the eyes/break fusion using occluder

What is a disadvantage of the Maddox Wing test?

• Unable to be performed with phoropter

• Require objective response

• Only measure near phoria

• Require additional instruments (pen torch and prism bar)
