eyes pa 3

lose peripheral vision, abnormal increase in IOP, caused by a blockage preventing outflow of vitreous humor , “halo effect” is a symptom and you see green halo when you look at lights. 

Glaucoma

slow increase in IOP, genetic. Reduced night vision 

Chronic open angle

rapid increase in IOP due to sudden blockage and require immediate treatment. Eye trauma 

Acute closed angle

causes blurry vision, develops over time 

Dry macular degeneration

central vision loss due to degeneration of the macula

Age related macular degeneration

lense of eyes become cloudy

Cataract

 age related condition characterized by gray, blue ring around cornea 

Arcus senilis

bleeding in the retina

Retinal hemorrhage

 small artery is seen crossing a small vein which results in compression of the vein with bulging on either side of the crossing

Arteriovenous nicking

yellow, distinct outline

Optic disc

Light orange part circular

Macula

Red to dark brown red

Retinal background

RRR and LLL rule. Search for red light reflex and slowly follow it inwards and adjust brightness as needed to see details within the eye 

Opthalmoscope

abnormal constriction

Mitosis

Abnormal dialation

Mydriasis

Unequal pupils

Anisocoria

Farsighted

Hyperopia

Bulging of eye

Exophthalmos

Drooping of the upper eyelid

Ptosis

20/200

Legal blindness

Lazy eye

Strabismus

Assess pupil reaction to light

Pupil art light reflex

Normal people will constrict when exposed to light

Direct reaction

Normally opposite people will also constrict

Consensual reaction

This reflex test cranial nerve two and three this is a direct and consensual response

Cranial nerve two and three

Shining the light at the bridge of the nose, and looking for reflection in both cornea’s should be symmetrical is which reflex test

Corneal light reflex

Cornell light reflex test

Cranial nerve 2,4, and 6

Focus on the finger then the wall look at the finger both eyes should move in

Accommodation and convergence

Accommodation and convergence test what cranial nerve

Cranial nerve 3

Moving fingers in an H shape

Extraocular muscles

This optic nerve is responsible for vision involved with consensual light reflex

CN 2

This nerve is responsible for the oculus motor which controls the pupils, constriction and eye movements

CN 3

The trochlear nerve is which cranial nerve. Superior oblique muscles

CN 4

The trochlear nerve, Superior oblique muscles

CN 4

The abduction nerve, Lateral rectus muscle

CN 6
