What is the Glasgow Coma Scale and what does it measure?
| | | | | | | | | |
The GCS measured level of consciousness and is scored from 3 to 15, with 3 being
| | | | | | | | | | | | | | |
the worst and 15 being the best. The score is calculated by adding together the
| | | | | | | | | | | | | | | |
scores from each of the three categories: eye opening, motor response, and
| | | | | | | | | | | |
verbal response |
What are miotics? | |
Drug that causes the pupil to constrict, decreasing IOP
| | | | | | | |
What are mydriatics?| |
Drug that cause the pupil to dilate, increasing IOP
| | | | | | | |
What is presbyopia? | |
Presbyopia is a common age-related disorder that results from the ciliary muscles
| | | | | | | | | | |
becoming less flexible and functional, effecting the patient's ability to see close
| | | | | | | | | | | | |
up. Usually begins around age 40.
| | | | |
What are cataracts? | |
A clouding of the eye's lens that can lead to vision loss. As the crystalline lens
| | | | | | | | | | | | | | | |
becomes more dense, light cannot reach the macula where vision is the clearest,
| | | | | | | | | | | | |
causing eyesight to appear cloudy.
| | | |
~The exact cause is unknown, but possible causes are: congenital (present at
| | | | | | | | | | | |
birth), trauma, disease, steroid use, over-exposure to UV light
| | | | | | | |
What are the 3 stages of cataracts?
| | | | | |
, 1. Immature: Lens is lightly cloudy and the cortex is mostly clear
| | | | | | | | | | |
2. Mature: Lens is entirely cloudy and can be removed easily from its capsule
| | | | | | | | | | | | |
3. Hyper mature: The normal lens protein is degraded and absorbed or escapes,
| | | | | | | | | | | | |
lens is yellow, shrunken, and the capsule is wrinkled.
| | | | | | | |
TRUE OR FALSE: "The lens can spontaneously dislocate and cause acute angle-
| | | | | | | | | | |
closure glaucoma." |
TRUE
Symptoms of Cataracts | |
- Distorted, hazy, or yellow vision.
| | | | |
- Poor night vision
| | |
- Glare is an issue because the light rays are scattered
| | | | | | | | | |
What is cataract surgery?
| | |
-Procedure to remove the lens of the eye and, in most cases, replace it with an
| | | | | | | | | | | | | | | |
artificial lens |
*Surgery is 95% successful | | |
*Most frequently preformed in people aged 65+
| | | | | |
*Usually done in an outpatient setting; eye centers
| | | | | | |
*Local anesthetic-safe |
What are the 2 cataract surgery removal methods?
| | | | | | |
1. Extracapsular extraction (ECCE)
| | |
* 98% of all procedures, used for mature cataract removal, remember: "E for
| | | | | | | | | | | | |
EASY removal" |
2. Intracapsular extraction (ICCE)
| | |
* Used for about 10% of hyper-mature cataract, remember: "I for ICKY removal"
| | | | | | | | | | | |
Sharp sudden pain in the eye could be a sign of what?
| | | | | | | | | | |
Hemorrhage or increased IOP | | |
