series

Easy operation

Sophisticated instrumentation need not be complicated. The HFA II offers a number of features

intended to make the instrument easier to use:

• Touch screen design speeds data input.

• Menu and icon commands simplify operation.

• On-screen video eye monitor is standard on all models.

• Confirmation screens reduce unintentional data loss.

• A keyboard and trackball or mouse can be connected to the HFA II as optional data

input devices.

Speedy testing

Carl Zeiss Meditec’s SITA™ testing strategies allow precise visual field measurements

with unprecedented speed. With the SITA strategies, users can obtain visual field information in

half the time it takes using conventional testing algorithms without compromising accuracy.

SITA represents the very latest in autoperimetry technology and it is only available with your

Humphrey Field Analyzer II.

Sophisticated data

The Humphrey Field Analyzer’s statistical software, STATPAC™, provides immediate expert

analysis with STATPAC™

system analysis of visual field test results. With STATPAC you can analyze test results at the time

of examination, store test results and analyze them at your convenience, or recall previously

stored tests to analyze for comparative purposes.

STATPAC includes several exclusive features to help you identify visual field change:

• Using results from a single test, STATPAC can point out suspicious areas that otherwise

might not be evident until subsequent tests were done.

• STATPAC can identify areas that look suspicious but which, in fact, compare favorably

with normals data.

• Using results from a series of tests, STATPAC provides a highly sensitive and informative

analysis of changes in the patient’s visual field over time.

• The Glaucoma Hemifield Test (GHT) compares points in the superior and inferior

hemifields to provide a plain language analysis of test results.

• The HFA II provides separate databases for STATPAC analysis. These include databases

for SITA and Blue-Yellow perimetry, in addition to the well-established databases for

Full Threshold and FastPac test results.

• Another database consisting of stable glaucoma patients is used with the Glaucoma

Change Probability Analysis for following change in the progress of the disease. This

analysis is only available with Full Threshold testing.
