SCREENING

PRINTOUT

FORMATS

It is the test strategy used in each screening test that determines the format of the printed test

results (see Table 7.3).

Table 7.3: Screening Printout Formats: All Screening Test Patterns

Strategy

Format Description

Two Zone

Points missed

Quantify Defects

Points seen  O

Numbers (in dB) show depth of defect

When you have tested both the right and left eyes for the same patient, you have the option of

printing a single screening test per page (referred to as “Screening Test” on printout selection

menu), or a combination of the right and left eye on one page (referred to as “Both Eyes”). To

obtain the screening printout for both eyes, screening tests may be central or peripheral but

not full field patterns (see Example 7.14). The printout of both eyes is also known as the

“O. U. Printout”.

The Quantify Defects Full Field screening test is printed on two pages. The first page consists of

the Full Field printout. The second page is an enhanced view of the Central 30 degrees,

allowing for easier reading of the central portion of the printout. If there are no defects

quantified in the Central 30 degrees, the printout will only be one page long. The printout will

be in the full field format.

Reading screening test

The type of test and test parameters are printed at the top of the printout along with the patient

printouts

data, test date and test time. Like threshold test printouts, screening printouts include reliability

indices to help you determine the reliability of the patient’s responses.

When a screening test uses the Threshold Related testing mode, the central (and peripheral)

reference level values are determined from patient responses and appear on the printout and

test screen. When the Age Corrected mode is used, the central (and peripheral) reference

levels display values based on the patient’s age.
