In the alternating cover test the two eyes are alternately covered with an occluder or "cover paddle" while the patient looks at a target which he can see clearly. The test is done while the patient fixates a distant target and again when he fixates a near target. When the occluder covers an eye, it is dissociated from its fellow and moves to its phoria position. When the occluder is removed, the eye resumes fixation. The examiner looks for the direction and amount of movement of the eye when the cover paddle is removed. If the patient is exophoric, his eyes diverge in the phoria position and the eye will move medially when uncovered. If the patient is esophoric, his eyes converge in the phoria position and the eye will move laterally when uncovered. An eye may also be hyperphoric (deviated upward) or hypophric (deviated downward) with corresponding motions down and up, respectively, of the uncovered eye.

Parts of the Exam- Eye Movements
Saccades:
Fixation:
Pursuits:
Saccades
Pursuits
Saccades are rapid, ballistic movements of the eyes that abruptly change the point of fixation. They range in amplitude from the small movements made while reading, for example, to the much larger movements made while gazing around a room. 
Fixation
Smooth pursuit movements are slow tracking movements of the eyes designed to keep a moving stimulus on the fovea. 
Fixation is the maintaining of the visual gaze on a single location.

Daltonism 
Color blindness
of basic colors:
Red, Blue and Green A distinction is made between: protanopes, who do not see red;
deuteranopes, who do not see green;
tritanopes, who do not see either blue or yellow.
Stereopsis
Near Point of Convergence
The closest point to which the two eyes can follow a target in toward the nose without losing fusion (diplopia
or suppression). Noted
as TTN if no break
occurs or noted in inches if there is a break or loss of fusion.
Also noted may be
discomfort (patient reported) or red face which denotes strain.
Tests and evaluates stereo depth perception for both gross stereopsis evaluation using six geometric forms from random dot backgrounds Tells us how the two eyes are working together.

This is a test utilizing red-green color dissociation. The patient wears red and green goggles (as a convention red in front of right and green in front of left). The test can be performed separately for distance and near vision. The interpretation of this test is as follows-
A) The patient sees all the four dots.
normal binocular response with no manifest deviation
B) The patient sees five dots.
uncrossed diplopia with esotropia, red dots appear
to the right; crossed diplopia with exotropia, red dots appear
to the left of the green dots.
C) The patient sees three green dots, suppression of right eye.
D) The patient sees two red dots, suppression of left eye.
E) This test is performed as various distances near, intermediate and distance to watch for variations. Doctor will typically “start where they are” where the patient is likely to have fusion based on previous testing.

Parts of the Exam-Fusional Facility/ Accommodation
Examination
of Pupils
MEM OD:
Doctor notes pupillary response to light. In most cases you may see the abbreviation PERRLA—pupils equal, round, and reactive to light and accommodation. You may also see notes about AO Pupil which is Alpha Omega Pupil where pupil does not hold constriction in bright light after a few seconds.

The doctor uses the Retinoscope to perform this test. The '''monocular estimate method''' is a form of dynamic retinoscopy used to objectively measure accommodative
response through a plus lens. Values normally attained when performing MEM are between and +0.50 diopters. Look for notes about bright and dim – bright is better than dim.
Accommodative Facility-
Cycles per Minute
Performed at distance with 3D BO/ 12D BI. Patient is instructed to keep a vertical line of 20/30 letters single and clear as base out prism and base in prism is introduced. Similar to the Binocular Prism Rock performed in therapy.
This test is usually done with a nearpoint reading card and a flipper with +/-2.00 lenses. The doctor will measure how many cycles of switching (eg. from plus to minus to plus) that the patient can achieve in 1 minute.

Measures horizontal or vertical deviation of the eyes, one with respect to the other, when fusion is interrupted. The phoria may be assessed by alternating cover test. The doctor will repeat this test many times to check for repeatability and stability.
To measure subjectively the relative horizontal or vertical deviation of the eyes, one with respect to the other, when fusion is interrupted
To measure subjectively the relative horizontal or vertical deviation of the eyes, one with respect to the other, when fusion is interrupted
Vergence Ranges- Noted with blur/break/recovery- Performed in phoropter for some patients or with prism bar for patients who have difficulty with in phoropter testing.
To measure subjectively the relative horizontal or vertical deviation of the eyes, one with respect to the other, when fusion is interrupted
SILO -In this area pay special attention to notes like SI or SO (under BO testing) or LI or LO (under BI testing) - this gives the therapist information as to how the patient perceives space and how reliant they are on visual information-

Parts of the Exam- Accommodative Amps
Vertical Range Dist:
Accommodative Amps OD:
Vertical Range Near:
Accommodative Amps OS:
 The maximum amount of accommodation that can be stimulated, by reducing plus lens power or by adding minus lenses, in an eye.
Normal amplitude of accommodation can be determined by using the following formula:
18- 1/3 of patient’s age (Morgan’s Expecteds) Or
15- ¼ patient’s age (Hofstetter’s Formula)
Sometimes on Accommodative Amps you will see a # then a dash and another #. The first number is the first “disruptive” lens or prism power but they are able to recover and got up to the higher level.

PRA:
Fused Crossed Cylinder– this test is done at nearpoint and evaluate how accommodation functions when a target has no meaningful symbols to read or be recognized (i.e. no cognitive demand).  The crossed cylinder tests measure how much plus can be accepted at near and help the doctor in the determination of a nearpoint prescription.
This nearpoint test evaluates the amount of increase that can be made in accommodation while convergence is held constant. Normal findings are to D in the age range of most of our patients.. Values below D may indicate an accommodative insufficiency. Our goal is “superhero” on most tests so that “average” becomes easy.
This nearpoint test evaluates the amount accommodation can be relaxed while convergence is held constant.
Normal findings are in the range of / >2.50: may indicate latent hyperopia <2.50: poor accommodation
Most of our patients are low hyperopes so should get “easy” with max around +3.00
