6.1.8. Evaluates glaucoma risk factors to detect glaucoma and refer accordingly.

Question 1

What do we look at to diagnose glaucoma?

Answer 1

1. VF
2. IOP
3. OD
4. AC

Question 2

What is IOP?

Answer 2

resistance and production balance : 10-21 is normal variation –> detamined by body position / exercise

Question 3

What rasies IOP?

Answer 3

1. age
2. bp
3. cyclo
4. steroids

Question 4

why does cyclo increase IOP?

Answer 4

The iris will bunch up + block the trab mechwork –> resistance to outflow

Question 5

what is ocular hypetension/

Answer 5

This is when the IOP is higher then 21 - normla disc + VF –> OHT = needs to be monitored cloesly for glaucoma risk

Question 6

What are the risk factors of primary open gluacoma

Answer 6

1. age
2. race - afro - black
3. thin cornea
4. higher myopia
5. FH

Question 7

Why is age an risk factor for POAG?

Answer 7

as we get older the drainage system gets less effective –> there is accumilation of debrus

Question 8

why are thin corneas a risk?

Answer 8

thinner corneas = under estimate the IOP

Question 9

why is high myopia a risk factor of POAG?

Answer 9

Longer eye ball = stretching of the optic discs support tissues = more prone to damage

PPA - more risk for glaucoma

Question 10

How can you tell the diffrence between alpha and beta PPA?

Answer 10

alpha is darker and more outside
beta is lighter and more inside
