Ocular Hypertension and Normal Tension Glaucoma

Question 1

the pathophysiology for the ocular hypertension is a problem with

Answer 1

the drainage structure

• IN THE CONVENTIONAL PATHWAY
• at the site of greatest reistance juxtacanicular
• theory is there are more GAGS being deposited

Question 2

what is the name of the GAG being deposited in the juxtacanicular tissue during OCULAR HTN

Answer 2

chrondoitin sulfate

Question 3

IOP, gonio, anterior seg evaluation, dilated ONH assessment, OCT rnfl and gciopl, HTVF 24-2 or 30-2 SITA STANDARD, SITA FAST, Pachs, fundus photos

Answer 3

is the standard glaucoma work up.

Question 4

Ocular HTN has the ability to convert to POAG. should we treat?

Answer 4

depends on the baseline risk factors, and whether txt is going to slow OR prevent the progression of POAG.

Question 5

explain the risk of progression to poag for patients who have OCULAR HTN. What did the study find

Answer 5

Conclusion:

At the population level, the medical management of ocular hypertension delays conversion to POAG.

Question 6

what number is needed to treat OCULAR HTN?

Answer 6

NUMBER NEEDED TO TREAT:

19.6 patients with ocular hypertension need to be treated to prevent ONE case of POAG over 5 years

Question 7

how can we predict conversion of ocular hypertension to primary open angle glaucoma? hence what data can we use to help us make a prediction ?

Answer 7

age (increase )
IOP
CCT
VCDR

Question 8

-this provides a estimated 5 year risk of developing early glauc in at least one eye

Answer 8

OHT calculator 
(have to enter IOP, CCT, AGE, and the VCDR) dont forget to enter the VCDR

Question 9

in terms of txt for ocular hypertension…what are your options?

Answer 9

monitor every 6 months
txt : medically or surgically

the TARGET IOP : 20% REDUCTION ANDDDDDD <24 mmHg

Question 10

normal tension glaucoma is the same thing as ____ tension glaucoma.

Answer 10

Low

Question 11

T/F: the only difference between POAG and Normal tension glaucoma (low tension glauc) is IOP.

Answer 11

true. the iop cut off between the two is greater than or equal to 22mmHg.
but the open angles, onh signs, oct signs, and HTVF signs are the same. its just iop that is different.
