Iggy: Eye & Vision Caring For Flashcards
Use (aseptic / sterile) technique when preforming an eye exam or instilling drug in the eye
Aseptic
Entropion
Why is it more common in older people
Turing inward of the eyelid causing Corneal Abrasions & Redding of Conjunctiva
More common: age-related loss of tissue support
Ectropion
Possible side effects
Turning outwards of the eyelid and not coming into contract with the eye
Reduced effectiveness of tears.
Cornea becomes dry
Hordeolum is….
Treatment of….
Stye (eyelid sweat gland infection)
Warm compresses 4x daily
Antibacterial ointmen
Chelation is….
Describe SE
Treatment
Notify HCP
Chalazion is inflammation of a sebaceous gland in eyelid.
SE: Redness, Tenderness, Painless Swelling. Later. Redness & Tenderness not present
Eye fatigue, light sensitivity, excessive tears
Treatment: warm compress 4x daily, ophthalmic antibiotic ointment.
Report: increase redness, Purulent Discharge, reduced vision
Keratoconjunctivitis Sicca is…
Drugs that may cause it
May follow vision enhancing surgery
Management;
Dry eye syndrome, results from tear production, composition, distribution
Drugs: antihistamines, beta blockers, anticholinergic
Management: Cyclosporine (Restasis) eye drops increase tear production
Artificial Tears
The Conjunctiva is…
Thin mucous membrane that covers ans protects the eye
Bacterial conjunctivitis is aka
However, conjunctivitis may occur with or without infection
Pink eye
Trachoma is…
Chronic conjunctivitis caused by Chlamydia trachomatis.
Keratoconus is…
Degeneration of the corneal tissue results: abnormal shape
Abnormal cornea may be fixed via 2 methods.
- A ring can be fitted around it and adjusted to change the shape.
- Keratoplasty: corneal transplant
How do cataracts happen
With age lens loses water and becomes thicker
Forming a cataract
Teaching to prevent cataracts
Avoid UV light wear sunglasses.
Avoid eye injury. Wear google during sports and work
Post cataract surgery
Creamy white, dry, crusty drainage on the eyelid appears
Best action to take
Nothing
This is normal
However, yellow or green drainage indicates infection
After cataract surgery a decrease in vision temporarily is normal and should be expected.
True ir False
False
Vision should improve same day
Best result will occur in 4 - 6 Weeks
Lid swelling
Flashes of light and shapes
Are normal events after cataracts surgery
False
How long to avoid water in eye after cataract surgery
Which house hold cleaning chore should you avoid. Why
4 - 7days
Vacuum, the posistion and quick movement may increase IOP
Difference between
Primary open-angle glaucoma
Primary angle-closure glaucoma
Primary open-angle glaucoma
(Most common, slow onset)
Primary angle-closure glaucoma
(Acute, Emergency)
Diagnostic
Open-angle glaucoma Tonometry reading
Angle-closure glaucoma reading
22- 32
> 30
Which type of patient should you avoid preforming a ophthalmoscopic exam on
Confused
Encourage to wear eye safety where (3)
Yard work, wood/metal shop, environment where drops or particulate matter is airborne
How often eye exam for older than 40
Yearly
Who should wear polarizing sunglasses outdoors
Everyone
Is it best EBP to ask a patient if they have a family history if vision problems
Yes
When instilling more than 1 type of eye drop in an eye
How long do you wait between them
5 - 10 minutes
Bending from the waist
Lifting more than 10 lbs
Sneezing, blowing nose
Strain bowel movement
Vomit
Sex
Head in dependent posistion
Wearing tight shirt colars
Alll do what
Increase IOP
Use this technique during administration antiglacoma eye drops
Purpose to prevent drops from traveling down duct and into nose
Punctal occlusion
Push on inside corner of eye for 2 minutes
Macular degeneration affects this part of the eye
Retina
2 types of Macular degeneration
Age-related ( Dry or Wet)
Or
Exudative
Retinal capillaries become blocked this this type of AMD
Growth of new blood vessles in macula, thin walls leak fluid
Dry
Wet
AMD affects this field of vision
Center
Exudative macular degeneration develops (slowly/quickly) decreasing vision and forms a blood clots under the macula
Quickly
Dry AMD has no cure
Treatment to slow disease includes
Dietary, antioxidantes, vitamin B12, carotenoids
Wet AMD can be improved how
Lazer to seal leaking blood vessel.
Ocular injection of growth factor inhibitors
