Phoria =
Intermittent Phoria = - Answer-Strabismus =
Intermittent Strabismus =
Phoria = both eyes aligned on the fixation point when fusion is intact
Intermittent Phoria =
◦BO prism for ___-deviations
◦BI prism for ___-deviations
◦BD or BU for ___-deviations - Answer-◦BO prism for eso-deviations
◦BI prism for exo-deviations
◦BD or BU for hyper-deviations
What are the 3 different types of Phorias - Answer-ORTHOPHORIA
HETEROPHORIA
HETEROTROPIA
Heterophoria
Latent deviation of the lines of sight
, PHORIA - both eyes aligned on the fixation point when fusion (binocular vision) is intact
Disruption to binocular vision (fusion) can cause the _______ (covered) eye to _____ to the ______
position. - Answer-Heterophoria
Latent deviation of the lines of sight
PHORIA - both eyes aligned on the fixation point when fusion is intact
Disruption to binocular vision (fusion) can cause the non-fixating (covered) eye to deviate to the
heterophoric position.
Heterotropia
____deviation of the line of sight of one eye
◦one line of sight is directed toward the object of regard; the other is oriented _____
aka "_____" - Answer-Heterotropia
Notable deviation of the line of sight of one eye
◦one line of sight is directed toward the object of regard; the other is oriented elsewhere
"Strabismus"
Heterophoria vs. Heterotropia - Answer-Heterophoria = when both are UNcovered, both eyes look
alighed on fixation point. Aka: PHORIA. You will find the phoria of one of the eyes by doing the Cross
Cover Test
Heterotropia: eyes look always deviated even when both eyes are UNcovered (with fusion). AKA:
Strabismus. To find out which eye is turning in or out, or up or down, you do the Cover and Uncover test
Use of the Cover Test
Determines if pt has ______ or _______?
Determines if either is present
Can determine if present at distance and/or near
Measures the_____, ______ and ______ of deviation - Answer-Use of the Cover Test
