Have you been familiar to this term? What is it actually? What are their functions? Find the answer on the explanation below.
Cardinal fields of gaze
In ophthalmology, cardinal fields of gaze is known as the six positions which turned by normal eyes. The works of eyes in making gaze direction is helped by the presence of these cardinal fields. In total there were six extraocular muscles and cranial nerves III, IV, and VI that work on the process. The position that is being the eyes direction are:
To produce a straight nasal direction, the eyes require the work from inferior oblique and the third cranial nerve.
Inferior oblique and the third cranial nerve are the two parts that works to make the up nasal direction.
To produce a down nasal direction, the eyes require the work from superior oblique and the fourth cranial nerve.
Lateral rectus and the sixth cranial nerve are the two parts that works to make the straight temporal direction.
To produce a down nasal direction, the eyes require the work from superior rectus and the third cranial nerve.
Inferior rectus and the third cranial nerve are the two parts that works to make the straight temporal direction. The down temporal direction is also known as the extraocular movement. The illustration of the six cardinal fields of gaze is shown as follows
Important findings to note
A nursing process of the six cardinal fields of gaze started by assessment cognitive level then followed by the application need of the client. After that, it is finished by having a psychological integrity. When assessing the six cardinal fields of gaze the smooth coordinated movement of the eye is the one finding that is important to note. This is the result of how the patients’ eyes perform on the eye test movement and how the muscle of the eye works to make the directions. There might be a case where an occasional mild nystagmus or jerking appeared in the test of eyes coordination movement. This finding is normal in extreme lateral gaze. On the other hand and perrla, the presence of nystagmus in all six cardinal fields could be the indication of abnormality. The patients need a further evaluation regarding these occurrences. When a procedure of corneal light reflex test is done to a patient, the expected result is a symmetrical corneal light as the response.

Testing the health of eyes is always including the importance of the pupil eye assessment chart. Many kinds of eye examination that you should know; the description will be as follows:
Assessment of visual acuity
The first part of eye examination mostly done is the assessment of acuity. This test can be done by the patient read the Snellen chart that hanged about 20 feet from his position. While reading the words in the Snellen chart, patient needs to cover one of his eyes. The test goes for both eyes. The next step is trying to find the correct vision by using several glasses with different lens like Pupil Reaction To Light. If you find the one that makes you see everything clearer with no dizziness, then it is the right lens that you should use everyday.
The next pupil eye assessment chart is the pinhole testing. This kind of test still examines the acuity of patients’ eye. The purpose of this test is to determine if the acuity problem caused by refractive error (and that still can be corrected by wearing glasses) or because of another process. Same as the previous test, pinhole testing using the snellen chart as one of the testing devices, but this time patients should wear a pinhole twice. The first using is with the pinholes up (below right) and the second one is with the down position (below left). The acuity issues can be confirmed to be related wit refractive problem when the deficit corrects with the pinholes in place.
The pinhole testing
Observation through external structure
A test of eyes could also done by examining the external structure of patients’ eye. Some of them are:
On normal eye, the eyelid should cover the same amount of the eyeball. Some people whose nerves (precisely cranial nerves 3 and 7) responsible for controlling the structure is damaged, will have the upper lids on one side of his eyes appear lower than the other.
For normal people, their sclera is white and surrounded by the iris and the pupil. For people who suffer from a disease on their sclera, theirs will appear yellow. It is the result of blood disorder that cause hyperbilirubinemia.
Conjunctiva is a transparent membrane that covers the sclera. In other word, it is the underside of the eyelids. For normal people their conjunctiva is invisible; except for the fine blood vessels that run through it. This layer can appear to be red when it is infected or inflamed. This condition is what we call as conjunctivitis. There is also an exception of anemic patients, for them the conjunctiva might appear pale. To identify whether it is health or not, you can gently apply pressure and pulling down your lower lid then examine the reflection.
The last eye disease related to pupil eye assessment chart is hemorrhage. Blood could also accumulate underneath the conjunctive. It happens when there was a rupture of small amount of blood.

Pupil Reaction to Light is narrowed but the pupils will widen when they see the darkness. Cataracts are eye diseases caused by white stains in the lens of the eye. Normal eye lens has oxygen and water so that light can penetrate the eye easily. The eye lens will always form a new cell. There are many factors that cause the lens of the eye to be solid, rough, hard, and opaque. Abnormal eye lenses cannot provide light to the retina and are sent to the optic nerve in the brain.
