EYE/VISION Flashcards
How would you explain procedure to pt
What we’ll be doing now is assessing your vision. This involves 3 seperate tests. First is PERRLA which tests your pupillary response, then a test of extraocular movemvent where you just have to follow my fingers with your eyes, then a snellen test which tests your visual acuity, I’ll be asking you to read some letters on a piece of paper from a distance. Is that okay with you?
How would you do the inspection and normal findings
Inspect first.
Inspecting size and shape - equal bilaterally and round nil bulging or deformities to the pupil. Sclera is white no jaundice, no oedema or discharge.
Pull down eyelid - pink(normal), red(inflamed), pale(anemia).
How will you ax extra occular movement and normal findings
Position self away from patient, finger held at 30cm away from nose
Ask client to follow your finger whilst keeping head still.
Use finger slowly and go in 6 cardinal gazes - like a cat whisker
Advise normal findings - smooth and parallel movement in all 6 cardinal gazes + no irregular movement
How will you ax visual acuity
Position snellen chart 6 metres away
Cover one eye and ask pt to read from the top
Then test other eye
Advise findings - 6/??? (# will be stated under the line) if they read half way a line then its the number plus 0.5
What does PERRLA stand for
Pupils equal round reactive to light and accomodates
How would you do PERRLA ax and normal findings
Get them to focus on something near you, bring torch from side of face then shine of pupil - check if it constricts / do it again and check for consensual response in other pupil. Repeat on other eye.
Describe response - rapid consensual movement in both pupils.
Accomodation
Ask the pt to focus on something near you while your finger is 10cm away from nose. Let them look for a few seconds then ask them to look at your finger.
Describe whats found - normal convergence of the eyes + constriction of pupils which is expected.
Questions to ask when u know your doing eye ax?
Any ocular issues or surgeries Contact lenses, glasses Hx of diabetes history of glaucoma or occular issues in family Occupational hazards - dust?
What is glaucoma
the nerve connecting the eye to the brain is damaged - can cause blindness
