OTM2 Exam With Complete Solutions 100% Verified
determines the closest point to the patient at which single vision can be maintained -
ANSWER NPC
the distance from the patient's corneal plane (or spectacle plane) to the target -
ANSWER Break measurement
after obtaining your break point, while moving the target back from the patient. you see
the eye turn and fixate. what kind of measurement is this - ANSWER objective
if the patient reports double or single vision during NPC, what type of measurement is
this - ANSWER subjective
the distance from the patient's corneal plane (or spectacle plane) to the single target -
ANSWER recovery measurement
what should you record if the patient never reports doubling of the target? - ANSWER
suppression
if examiner was able to move target to the bridge of the nose without the patient losing
fixation or reporting doubling of the target then record - ANSWER TTN
normal break point NPC - ANSWER 3-5 cm
abnormal break is recorded as greater than - ANSWER 12 cm
"normal" recovery is within - ANSWER 3 cm of break point
,assess the presence and measure the magnitude of a heterophoria or a heterotropia -
ANSWER Cover test
waiting 3 seconds after uncovering one of the eyes during UCT allows for the patient to
attempt to - ANSWER recover BV after uncover
endpoint of prism neutralization is where - ANSWER no movement is seen (can split the
difference if more than one power)
movement is observed in ACT but no movement is seen in UCT - ANSWER phoria
movement is seen in both the ACT/UCT - ANSWER tropia
no movement is seen in either UCT or ACT - ANSWER ortho
if VA is unequal, then prism bar should be placed over the - ANSWER better seeing eye
(usually non-deviating)
neutralizes ESO movements - ANSWER base OUT
neutralizes EXO movements - ANSWER base IN
Morgan's Norms for Distance - ANSWER 1 ESOphoria -- 2 EXOphoria
morgan's norm's for near - ANSWER ortho-- 6 exophoria
literature cites this amount as required for comfortable near work - ANSWER 4-6 PD
exophoria
,left exotropia:
with the right eye covered, the left eye will turn which way to pick up fixation - ANSWER
in
left exotropia:
with the right eye covered, it will still turn which way due to yoked movement - ANSWER
out
Tropia: what is determined by UCT? - ANSWER -Magnitude
-frequency
-laterality
-direction
for a phoria: what is determined by UCT? - ANSWER nothing!
Tropia: what is determined by ACT? - ANSWER Magnitude and direction
For Phoria, what is determined by ACT? - ANSWER magnitude and direction
IF you find a trope on UCT, cover the ____ ____ to note if constant, intermittent, or
alternating - ANSWER fixating eye
if a patient reports blur, it means they - ANSWER will most likely break into 2 images
fairly quickly
if you have both an objective and subjective measurement.. which is more notably
, "important" - ANSWER objective
an accommodative target is generally used for - ANSWER pre-presbyopes
BOTH an accommodative target and a non-accommodative target - ANSWER fixation
stick
transilluminator target generally used for - ANSWER presbyopes
if TTN then no - ANSWER recovery
an entrance test that determines the patient's resting position of their eyes (when
dissociated) - ANSWER cover test
cover test measures tonic - ANSWER convergence at distance
excessive tonic convergence = - ANSWER eso
deficient tonic convergence = - ANSWER exo
measures:
-tonic convergence
-accommodative convergence
-proximal convergence at near - ANSWER Cover test
ONLY looking at ____ eye for both UCT + ACT - ANSWER uncovered
During ACT, you should move the occluder directly across to maintain - ANSWER
