Study Notes
Vocab
-
Emmetropia is perfect vision.
-
Hyperopia means far-sightedness, objects far away are seen clearly.
-
Myopia means near-sightedness, objects up close are seen clearly.
-
Astigmatism is the uneven curvature of the cornea of the eye.
-
Miosis is pupillary constriction.
-
Mydriasis is pupillary dilation.
-
Presbyopia is the narrowing of the vision field with age involving a loss of peripheral vision.
-
Arcus Senilis presents as a blue rim around the outer edge of the cornea and occurs with age.
-
Ptosis is the drooping of the eyelid, which can be caused by Lyme disease, Bell's palsy or stroke.
-
Ptosis is measured by looking at the upper lid and light reflex via an MRI.
-
Aniscoria is unequal pupils.
-
Bell's palsy is cranial nerve VII.
Medication administration for eyes & ears
- Do not touch the dropper to the eye when administering eye drops.
- The lower lid can be a pocket for the eye drops.
- Apply gentle pressure in the intercanthus for drugs like beta-blockers (Timolol), used for glaucoma.
- Wait 5 minutes between administrations of two different medications in the eyes.
- Do not share eye ointments.
Cataracts
- Cataracts are the opacity of the lens, underneath the iris.
- Cataracts can occur with aging but can also affect pediatric patients.
- Risk factors includes trauma, metabolic disorders, and medication side effects.
- Symptoms include cloudy vision, glare or sensitivity to light, double vision, eye misalignment, as well as fading or dulling of colors.
- After cataract surgery, patients can regain color and improved vision.
After Lens Surgery
- There is a potential for increased intraocular pressure (IOP) for 2-3 weeks after lens surgery.
- IOP is at greater risk when a patient bends at the waist, lifts more than 10 lbs, sneezes, coughs, blows nose, strains for bowel movement, vomits, has intercourse, changes head placement, or wears tight colored shirts.
