Anatomy
What is the sclera?
Responsible for vision and light perception.
What is Cranial Nerve II (Optic)?
Most important examination to perform when a patient presents with an ocular complaint. The vital signs of the eyes.
"Pink Eye."
The pupil constrict as a result of light shown into the eye.
Space behind cornea filled with aqueous humor.
Responsible for pupillary dilation and lid elevation.
What is sympathetic fibers?
Term for Near-sightedness
What is myopia?
Ruptured blood vessels in the eye caused by straining or coughing.
What is subconjunctival hemorrhage?
Light is shown into one eye, and the other eye constricts in response.
What is consensual reaction?
Middle, vasculature layer of the eye.
What is Choroid?
Responsible for superior oblique muscle, allowing for down and out gaze.
What is Cranial Nerve IV (Trochlear)?
Term for normal (20/20) vision.
What is emmetropia?
Sagging or outward turning of an eyelid.
Unequal pupils of 0.4 mm or greater.
What is Anisocoria?
Yellow, round spot at back of eye.
What is optic disc?
Responsible for lateral rectus muscle, allowing for lateral gaze.
Cranial Nerve VI (Abducens)?
Cornea is flattened out, producing blurred or fuzzy vision.
What is Astigmatism?
Infection of the tear (lacrimal) sac usually due to a blockage in the tear (nasolacrimal) duct.
What is dacryocystitis?
Increased convexity of the lens that occurs when the eye focuses gaze from far to near object. Due to contraction of the ciliary muscle.
What is accommodation?
Sharpest point of vision containing the highest concentration of cones.
What is fovea centralis?
Responsible for super, medial, inferior rectus muscles, and inferior oblique muscles. Controls elevation of lid, parasympathetic fibers to lid, and ciliary muscle.
What is Cranial Nerve III (Oculomotor)?
Inability of the lens to change shape, causing difficulty with accommodation.
What is presbyopia?
Chronic, slow growing scar tissue seen over the eyelid.
What is Chalazion?
The pupillary near reaction tests for these 3 things.
What is pupillary constriction, convergence, and accommodation of the lens?
