PER-RLA

PER= Pupils equal and round


RLA= reactive light accommodating

Anisocoria

Unequal pupillary size


Happens in 20% of people


Worry

CN 1

Olfaction

Parasympathetic activity

Light in someone’s eyes making them constrict

CN 3 & 4 are located in

Midbrain (the nuclei)

CN 5,6,7,8 located in

Cross PONDS (bridge) midbrain to mandala.

CN 9,10,11,12 are located in

Brian stem in the mandala (really important for gag reflex)

CN 2

receives all information. Afferent nerve. Arriving nerve. Something that you can see is revived by cranial nerve.

CN 3

Parasympathetic activity.


Contracts the eyes


&


Holds eyelid up

Nastagness

Dancing eyes

Ptosis

Drooping of the eyelid. Cranial nerve damage or systemic neuromuscular weakness


Caused by CN 7 not just CN 3 and caused by sympathetic chain.

Hornersyndome

A result of blockage of sympathetic nerve stimulation. Unilateral small regular pupil that is no reactive to light. Ptosis and anhidrosis of the same side accompany the pupillary signs.


* Ptosis: drooping eye. miosis:constricting pupil, anhydrosis:loss of sweat on the face

Miosis

Decreased pupil size, constricted. Happens with use of narcotics, damage to ponds or a result from glaucoma treatment.

CN 3

Pulsy (explain more from book)


(Midbrain stroke)

Two common finding in the eyes of geriatric patients (45 and older)

1) presbyopia: inability to focus, inability to accommodate for near vision


2) dryness of eyes

Entropion

Inward eyelid (senile cause)


*inversion

Ectropion

Outward eyelid (senile cause)


*eversion

Cataract

Blurry, low definition, inability to preview colors.


Reversible blindness



(The lens of the eye has developed emphatheleal cells. The cells shed and recycle and can’t go anywhere. So the stuff builds up.

Cataract surgery time

One month interval to change the lens

Macular degeneration

Leading cause of blindness in US in geriatric pts. Loss of central vision. Clear and crisp.


Happens more in males then females.


*peripheral vision stays in tact. Risk factors: hypertension and smoking

Leading cause of blindness in the world

Diabetes

Angiogenesis

(Pathalogic) look up in book

4 Micro vascular Damage from diabetes are:

Retinopathy


Neuropathy


Nephropathy


Cardiomyopathy

How many pokes should diabetes pt do?

8X a day

HGA1C > 11 means

Blood sugar is above 300 average a day. Causing osmotic damage. Glucose goes i to cell, water follows.

Acute glaucoma

*Ocular emergency: Immense amount of pressure behind the eyes. Due to blocked flow or fluid from anterior chamber. Pupil is oval shaped and dilated. Cornea appears cloudy with corcumcorneal redness. Pain onset is sudden and accompanied by halos around lights and a decrease in vision.


*NV and abdominal pain: Occult, facio, Espophago, Vago, Abdominal Nerve


Nothing to do with hypertension. Closed angle glaucoma is worse.

Blepharitis

Any inflammation of the eye lids


Staphylococcal infection leads to red, scaly, and crusted eyes. Burns itches and tears

Basal Cell Carcinoma

Usually seen on lower lid and medical canthus. A papular appearance


Chalazion

Inflammatory lesion of the eyelid. A firm, non tender nodule of eyelid, arising from infection of the meibomian gland. Not painful unless inflamed.


* obstruction of the sebaceous gland

Hordeolum

A stye. A staph infection. Puss in the middle. A bacterial infection.

Conjunctivitis

Layer that cover sclera that you don’t see. That layer can get Infection/ inflammation

Pterygium

Surfers eye


Non cancerous growth that develops from conjunctiva and extends to sclera


*Collagen breakdown spreads into the cornea

Pingueculae

Surfers eye


Yellowish nodules that are thickened areas of the bulbar conjunctive. Caused by prolonged exposure to the sun wind and dust


* Fibrovascular growth in the inner Canthus

Adies tonic pupil

Sluggish pupilares response. Usually unilateral but can be lateral.


Viral issues

Talking to someone who’s blind:

Speak directly to their face

Talking to someone who is hearing impaired:

Go on the side they have good and speak clearly to them on that side. Do not scream.

Angryll Robastin

Both pupils constricted. The light reflex is absent but accommodation is present.


(Prostitutes eye) syphilis, tumor or narcotic use

Hornersyndrome

Book

How to look into Ottis Media

Look in, pull pinna back, push on tragus.. if pain and erythema might be otitis exterma


Expected: should look pearly grey tympanic membrane


Infection= purulent fluid

Otitis externa is

Swimmers ear. Avoid swimming for a week.


Pain and erythema on pinna and tragus

Otitis media is normally caused by

Strep throat because it travels to the middle ear and the membrane now looks errythmatoc.


Purulent drainage=infection


Clear drainage: basal skull fracture, cerebral skull leakage.

Otitis externa

Ear canal is externa

Romberg

Test of procioception


1. Vision


2. Inner ear intact


3. Peripheral neuropathy


If you take one component away you should still have perception.

Rinne test

Air conduction is better than bone conduction. By ration of 2:1


Tap tuning fork and place on mastoid bone to feel vibration.

Webber test

Sensory neuro exam.


Test inner ear disease.


Place Tunning fork above head and should feel vibration to both sides.

CN 3, 4 & 6

3) oculomotor


4) trochlear


6) abduces


Control movement of the eye

CN 5
