 Prof.
Dr. Sayed S E H Saif


Table 1: the combined probability of IOP with C/D ratio which
predicts the probability of glaucoma in the next 5 years
How to use this table
 Measure
the IOP
 Examination
of fundus for C/D ratio
 Look
in the table for the corresponding
probability
 Then
see the color of the probability
 Manage
the patient according to the
probability
then
 See
the Target IOP for each CD ratio

Management

Normal: nothing to be done

Possible :
observe

Probable:
treat and observe

Highly probable: treatment vigorously & observe

Definite: full tolarable treatment, laser or surgery
& observe
Example
 Measure
the IOP
 Examination
example 0.5
example 25 mmHg
of fundus for C/D ratio
 Look
in the table for the corresponding
probability (0.22)

Then see the color of the probability

yellow

Manage the patient according to the probability
(yellow color is for observation)
Target IOP
 There
is no target IOP for this patient
because he is under observation not
treatment
Other examples
 The
following table contain several
examples with their probability at the
bottom row
