EENT/eye

Cross eye

removal of the eye

Pupils equal round and reactive to light and accomadation

Secrete distribute and drains tears to cleanse and moisten the eye

clear fluid that sits in anterior cavity of eye. assists in maintaining intra occular pressure

enters and leaves cornea, enters acqueous humor, enters and leaves lense, enter vitreous humor

• myopia
• occurs if the eyeball is too long or the cornea has too much curvature
•  

hyperopia, eyeball is too shorts or cornea has too little curvature

11-21

low intraoccular pressure  less than 5

high intraoccular pressure >21

measures the anterior chamber of eye pressure

tear production test

looks for corneal tears

color blindness

test for depth perception using grid. looks for disturbances of macula and retina

checks for blockages using dye. issues from cancer, diabetic retinopothy etc

causes blindness, increased intraoccular pressure

rare heridity disorder

gradual vision loss, macular dystrophy, yellow or orange lesions in the macula

fat deposits around cornea

blocked tear duct

• conjunctivita, or inflammation of eye in newborn
• can be caused by
• STD
• blocked tear ducts
• bacteria from moms skin (staph)pseudomonas (bacteria from moms GI tract)

cancerous tumor that originates in retina of newborn, rare conginital disorder

• lazy eye (most common vision problem)
• treat with
• eye patch (works best)
• special glasses
• surgery

dialate in dim light and for far vision, constrict in bright light light and for near vision

• causes blurred vision
• due to irregular shape of the cornea or an irregular curvature of the lens inside the eye
• prevents light from focusing properly on the retina so vision is blurred at any distance
• hereditary
• from birth

• chronic conjunctivitis caused by chlamydia
• significant cause of blindness
• contagious

• epithelium stroma (90%)
• endothelium
• then outside layer

• inflammation to the cornea, scarring of the keratitis can lead to blindness
• causes
• tearing
• pain
• gritty sensation
• decreased acuity
• spasms
• discharge

disrupts the clarity of the cornea which is vital to focusing of light on the retina

local necrosis of the cornea may be caused by trauma, infection or the misuse of contact lenses 

accumulation of cloudy material in part or parts of the normally clear cornea

• progressive thinning of the cornea typically affecting teens and young adults
• treatment corneal transplant
• pr laser surgery

corneal sloughing

sty (painful abscess)

• granulomatous cyst or nodule of the lid
• usually no pain
• conjunctiva

• antibiotic ointments or drops
• warm moist compress
• I&D (incision and drainage)
