1

what is a strabismus

crossed eyes deviation of one eye from the other when looking at an object

2

how common is strabismus (age)

can be normal in infant until age 4 months. after needs evaluation

3

what causes strabismus

most commonly caused by weak or hypertonic muscle in affected eye

4

what are the manifestations of strabismus

deviation of eye
diplopia (double vision)

5

what is cataracts

development of opacities of the ocular lense

6

what age do cataracts most effect

some formation expected by age 70
you will have them

7

what is the patho of cataracts

lense becomes stiff and opaque with age

8

what are the forms of cataracts

degenerative (most common)
congentially

9

what are the manifestations of cataracts

1. decreased visual acuity with blurred vision
2. increase in glare
3. decreased color perception
4. white light reflex (instead of red) in pupil area

10

what is glaucoma

increased intraocular pressure in anterior eye above normal of 13-22 mmHg of aqueous fluid

11

what age does glaucoma normally affect

increased between 45-60. second leading cause of blindness

12

what does aqueous humor usually do

maintain pressure in eye and supply nutrients to lense and cornea

13

what is the patho of glaucoma

obstruction to outflow of aqueous humor with resulting increase in amt of fluid and pressure in eye. pressure in eye impairs blood flow to retina with subsequent loss of acutiey

14

what is open angle glaucoma

90% chronic obstruction

15

what are the manifestations of chronic glaucoma

1. develops slowly without obvious symptoms
2. loss of peripheral vision
3. loss of central vision
4. blindness

16

what are the mani of acute glaucoma

1. sudden severe eye pain
2. nausea and vomiting
3. decrease in vision

17

what is otitis media

inflammation of middle ear

18

who does otitis media affect

1. 71% of kids had one episode before 3 yoa
2. premature infants
3. down's kids
4. babies fed in supine position

19

why does otis media mostly happen with children

the eustachian tube is shorter more horizontal and more distensible which predisposed children to otitis media

20

what are the two different types of otitis media

suppurative (infection)
effusion (fluid)

21

why does suppurative otitis media happen

post upper respiratory infection (URI)

22

what will you find when examining suppurative oitits media

red bulging immobile tympanic membrane (TM)

23

what are the complications of suppurative otitis media

perforation and sclerosis of TM with hearing loss and delayed and poor speech

24

what are the clinical mani of suppurative otitis media

fever
fussiness
ear pain
pulls on ear
hearing loss

25

what causes effusion otitis media

can follow suppurative or seen in chronically with allergies

26

what will you find when examining effusion otitis media

1. dull gray or yellow TM
2. trapped air and fluid with closure of eustachian tube
3. fluid thickens and forms "glue ear"

27

what are the clinical mani of effusion otitis media

doesnt look sick
decreaed hearing
ear feels "Full"
