HA 2 exam eye tests
Confrontation test
-Confront the peripheral , Testing peripheral vision - The Tester Covers the same eye for tester and testee. The tester moves their hand around in the peripheral. If tester sees it, then the testee should see it too. -Tester must have good vision to do this test to testee.
a Person with which type of eye disease will have a hard time with a Confrontation test?
-Glaucoma sufferers will most likely fail this test because they have a hard time with peripheral vision.
Pupillary Light Reflex
-Hand at nose to separate viewing area for vision. -Tester makes Light comes in from the side The DIRECT RESPONSE is the eye constricting to that light. THE CONSENSUAL RESPONSE is the other eye (who did not see the light) restricting as well.
Diagnostic Positions Test (Cardinal Fields of Gaze)
-Lead the eyes through the six cardinal positions of gaze will elicit any muscle weakness during movement. -Ask person to hold head steady and follow finger. -Progress clockwise in each direction. -A normal response is parallel tracking of the object with both eyes -Tests Cranial nerves III (Occulomotoer), IV (Trochlear), and VI (Abducens)
To test for Perrla, which 2 tests do we need?
-Pupillary light reflex & -Accommodation Test

Which tests do we use to test Extraocular eye muscle function?
First do the Corneal Light Reflex if test is abnormal, go to next test which is Cover test. Diagnostic Positions Test (Cardinal Fields of Gaze)
Cover test
Have patient cover one eye. make sure that uncovered eye doesn't bounce around. Then check covered eye to see if it jumps around as well. The eye muscle should not jump on either eye.
Perrla means
Pupils equal, round, reacting to light, and accommodation
Corneal Light reflex
Take a penlight right to the middle of the eyes. You should see a reflection in the same spot on each eye. Record your findings as such. Example: Reflection is noted at the 2 oclock position bilaterally If this test comes up abnormally, then you would proceed to do the cover test.
Accommodation Test
The Testee looks over the Testers shoulder at a far away object (clock) Now the Testee looks at the Testers Nose. Eyes should dilate to look at the far away object (clock) and eyes should constrict when looking at the Testers Nose (near object), Thie eye should accommodate to the near object.

Visual acuity test
She said almost every eye test will be on her test while she was lecturing
a little bit later she said she really wants us to know Pupillary Light reflex, Perrla, Diagnostic test, confrontation test, and corneal light reflex. Im just going to study this whole eye quizlet i made.
Convergence
is the ability of the eye to simultaneously demonstrate inward movement of both eyes toward each other. This is helpful in effort to make focus on near objects clearer. This should happen when looking at a far away object and then a near object.
