Eye OSCE Flashcards
What should you look for with inspection of the eye?
symmetry
orbits
lids and lid margins
sclera
conjunctiva
pupils
Describe the steps that you should use for eyelind eversion
Used in order to look for a foreign body
Patient looks downward, fingers pull the lid down and the cotton swab or finger is placed on the upper tarsal border
The lid is pulled up over the finger and everted
Basically pinch and pull up
_______ is when the pupil is exposed to a light source and constricts
Direct
This is when one pupil is exposed to light and the other constricts
Consensual
This is when the pupils constrict as the object comes closer to the eyes
Convergence
______ is unequal size of the pupils
Anisocoria
What is the average pupil size?
4 mm
How do you test for a red reflex?
Using the ophthalamoscope, the patient should look directly at the light from an arms ligth away
________ is another word for the white reflex and can indicate a serious pathology like a congenital cataract, retinal blastoma, retinal detachment, or other serious conditions
Leukocoria
_________ is a neuroectodermal malignancy arising from embryonic retinal cells; can cause childhood blindness; leukocoria is present before
retinoblastoma
What cranial nerves are being tested with the cardinal signs of gaze?
3, 4, 6
What is the purpose of the cover and uncover test?
Used to identify weaknesses of the EOM
eyes should remain syncrhonous
_______ is the ocular ataxia or rhythmical oscillation of the eyes tested with horizontal eye motion
nystagmus
Describe the eyes in the caloric reflex
If there is cold water inserted into the ear, the eyes move AWAY in the slow phase, which means that nystagmus is TOWARDS in the fast phase
How do you test for visual field confrontation
Ask patient to look directly into your eyes as you stand about an arm’s length away
Imagine a bowl between you and hold your fingers at arm’s length and wiggle your fingers as you move them along the edges of the bow approaching the patient’s central visual field
Estimate the extent of the peripheral vision
If you suspect loss in a visual field, test each eye by patient covering one eye, you cover your own eye opposite, then use one hand to wiggle along the imaginary bowl in that visual field– if you can see the wiggle, so should the patient – then repeat with the other eye
