Test 3: Sensory Alterations Flashcards
Types of Eye trauma
blunt, foreign body, penetrating, burn, chemical injury
blood in interior chamber and covers part of pupil
hyphema
caused by orbial blowout fracture- results in instability of the muscles in the eye
subconjunctival hemorrhage
Painless loss of vision
photopsia
light disturbances caused by tear/detachment of retina
floaters
take laser to reattach retina in the back of the eye where it needs to be
photocoagulation
sinch around eye and put silicone implant or put gas bubble to push retina back in place
scleral buckling
eye drops that dilate pupol
midriadic drops
lens of eye is cloudy or opaque
cataract
put enzymes on lens of eye to liquefy it and then suck it out- cataract treatment
phacoemulsification
open up capsule lens is in and lift it out
extraoccular extraction
age related change in macula in the back of the eye
macular degeneration
daily assessment, ask patient to cover one and and see if any lines on it bend or are wavey
Ampler’s Grid
Two types of macular degeneration
Dry and Wet
Tiny yellow spots, central vision loss, slower onset, vita A, E, leutine, monitor
dry macular degeneration
proliferation of abnormal blood vessels, straight lines look crooked,
Wet macular degeneration
Treatment of wet macular degeneration- stop overgrowth of blood vessels- injection in the eye
Vascular Endothelial Growth Factor Inhibitors (VEGFI)
Chronic disease of inner ear (fluid balance) with vertigo, hearing loss, and tinnitus
Meniere’s Disease
surgical procedure to treat meniere’s disease
Labrynthectomy
The two types of Glaucoma
Open Angle Glaucopen, Primary Angle Closure Glaucoma
Family history, no eye pain, usually bilateral, gradual loss of peripheral vision
Primary Open Angle Glaucoma
Sudden excrutiating pain, colored haloes around lights, blurred vision, occular redness, rapid permanent loss of vision
Primary Angle Closure Glaucoma
Device to measure intraocular pressure
Tonometer
Decrease blood vessels in the eye and therefore decrease pressure (treats glaucoma)
Prostaglandin agonist
Decrease production of aqueous humor.
Beta Blocker/ Adrenergic Agonist
Increase outflow of aqueous humor by constricting pupil
Cholinergics (Miotics)
Diuretic used to reduce production of aqueous humor
Carbonic Anhydrase Inhibiter
Use laser to open up structures to enhance outflow of aqueous humor
Argon Laser Trabeculoplasty
Incisionally open tract for aqueous humor to escape
Trabeculotomy
