Modified thorington arrow and numbers test provides information as to both (tropia/phoria) and stability
phoria
Thorington is checking for __
phoria at distance
the teste with the white diamonds and black dot in one is testing for ?
monoculare visual acuity in a binocular field
suppresion is when imporvement occurs under (binocular/monocular) conditions
binocular
in the keystone visual acuity exame withthe numbered squares signboards the pt (does/doesn’t) wear habitual perscription
does
How many failures does the pt get to have in a row in order to record the VA on the keystone
2

hyperopia
in the lateral phoria at near what is the first thing the pt needs to do?
close eyeys
is movement expected in the lateral phoria at near?
yes
what are some keystone findings?
over convergence, underconvergence, anisometriopa , reduced VA, reduces stereopsis, vertical misalignment
