every 2 years routine; every 1 year if contacts
27

every 1-2 years
28
What is presbyopia?
lens loses flexibility for loss of focusing ability
29

hyperopes
31
What temporary symptoms can computers and associated eyestrain cause?
blurry vision, dry eye, HA
32
What permanent issues can computers/eyestrain cause?
none
33
What are strategies to reduce eyestrain with computers?
1) OD/MD computer glasses or vision therapy 2) visual break q15m 3) top of monitor 10 degrees below eye level, 4) control glare 5) use full-spectrum (incandescent) light source, 6) artificial tears before and after 7) humidifier during the winter
34
How often should 50 year olds be getting eye exams?

39
What are symptoms of a torn retina?

What are the risk factors for glaucoma?
age, ethnicity, f/h, smoking, eye trauma
47
What are the treatments for glaucoma?
1) medicated eye drops/pills 2) laser surgery 3) tube instillation 4) Rx
48
What Rx therapies are used for glaucoma?

49
Which Rx therapies for glaucoma function at the ciliary body to decrease inflow?
CA inhibitors and beta-blockers
50
What Rx therapies for glaucoma function to increase uveoscleral outflow?
alpha-2 agonists and PG analogs
51
What Rx therapies for glaucoma function to increase trabecular outflow?
pilocarpine
