31
how do you treat conductive hearing loss?
1. antibiotics- treat infections
2. surgery- ossicle replacement
3. wax buildup removed
32
how do you treat AMD?

36
what is the round window?
- opening covered by membrane

what is the function of the sensory ligaments?
- connects lens to ciliary muscles
- when ciliary muscles contract, tenion released on sensory ligaments, allowing lens to become rounded
38
how do you monitor AMD?
1. regular eye tests
2. retinal imaging
3. visual acuity tests
39
what is the function of the ciliary muscles?
- help change shap of lens
40
what is the middle ear?

what is cataracts?
proteins in the eye’s
lens clump together, clouding lens.
43
what is the function of the conjunctiva?
- forms thin layer of protective membrane covering front of eye & lines inside of eyelids
