Test Chart 2000 PRO turns a standard PC into a powerful and versatile Test Chart for Optometrists, Ophthalmologists, Orthoptists and other eye care professionals. The program offers an unrivalled suite of test charts and vision tests. Here is what the reviewers say:
“The days of wall charts and projectors are numbered”
“Test Chart 2000 is the single most important development in clinical vision assessment in decades”
“Other systems have attempted to copy Test Chart 2000 but it is leagues ahead of the competition in terms of the range of tests and user friendliness”
Since its launch in 2000, Test Chart 2000 has been installed in over 2500 consulting rooms in the UK and overseas. It has won a number of awards for innovation and is backed up by research and development by a team led by Professor Thomson.
Simply install the software on your PC, mount a flat panel display on the wall, enter the screen viewing distance, perform a simple calibration and you have the Test Chart of your dreams!

UNRIVALLED SUITE OF VISION ASSESSMENT TOOLS
|
|
Snellen charts: The Snellen chart remains the most popular chart design among some clinicians. A range of different optotypes can be displayed in Snellen format including British, Sloan, Sheridan-Gardner, Landolt Cs, Tumbling Es, Lea symbols, Lea numbers and Kaye pictures. A single row or column can be shown and a range of cursors are available to isolate specific letters or rows
|
|
|
|
LogMAR charts: The LogMAR chart is a superior design to the Snellen chart and has been used in research laboratories for many years. An increasing number of clinicians are making the switch and it is likely that this chart format will become the standard in years to come. A wide range of optotypes can be displayed in LogMAR format. A single row or column can be shown and a range of cursors and available to isolate specific letters or rows.
|
|
Single letter charts: It is sometimes easier to show a single letter, particular when dealing with children and those with learning difficulties. The size of the letter can be changed in 0.1 logMAR steps and crowding bars can be added. A wide range of optotypes can be displayed in single letter format
|
|
|
|
Contrast Sensitivity Charts: Test Chart 2000 PRO includes a Pelli-Robson type test of contrast sensitivity. Patients are required to read triplets of letters with decreasing contrast. The minimum contrast required for the patient to read 2 out of the 3 letters is recorded as the contrast sensitivity. This measurement is partivular valuable for patients with cataracts and various neurological conditions such as glaucoma.
|
|
Cross-cyl targets: A range of targets are included for use during the cross-cylinder test. Targets include rings and dots of different sizes, which may be shown singly or in pairs.
|
|
|
|
Fan and block test: The fan and block test remains a useful test for identifying and correcting astigmatism.
|
|
Duochrome tests: The duochrome test provides a rapid method for assessing patients’ refractive status. Test Chart 2000 PRO allows various targets and optotypes to be presented against a duochrome background.
|
|
|
|
Phoria tests: Test Chart 2000 includes targets for use with the Maddox rod and a test for associated phoria.
|
|
Associated Phoria tests: The patient views the bars through the red/green spectacles provided. The bars are moved until they appear to be aligned and a measure of the associated phoria in prism dioptres is displayed on the screen.
|
|
|
|
Fixation disparity tests: Test Chart 2000 PRO includes an improved fixation disparity test which requires the use of red and green spectacles (provided). The unique design ensures good binocular lock and stable accommodation.
|
|
Worth 4 dot test: The Worth 4 dot provides a quick check for suppression. In this implementation the patient wears red / green spectacles (provided) and is asked how many dots the can see. 4= binocular, 3 = Left suppression, 2= Right suppression.
|
|
|
|
Stereopsis: At last - a distance stereopsis test. Use random dot stereograms to asssess steropsis. Dynamic generation of stereograms allows the disparity of the images to be adjusted to provide an accurate assessment of stereopsis. Generate shapes or letters
|
|
Vernier acuity has been shown to be useful in assessing the potential vision of patients with cataracts. Simply measure the minimum displacement require for the patient to detect that the two bars are mis-aligned.
|
|
|
|
Fixation targets: Test Chart 2000 PRO includes over 200 different images for fixation including photographs, cartoons and a selction of spots and crosses. The images are arranged in groups and a slide-show of the images within a group may be shown during retinoscopy or opthalmoscopy for example. Add your own images by simply dropping them into a directory.
|
|
Task images: Patient having problems seeing the TV or reading teletext? Why not show them these images on the test chart. Use the task images supplied with Test Chart 2000 PRO or add your own images by simply dropping them into a directory
|
|
|
|
UK number plate tests: The "number" plate test remains the only statutory test of vision required for driving in the UK. Test Chart 2000 is capable of exactly replicating a series of front and rear number plates using the exact fonts and character spacing. The number plates can also be presented against a variety of backgrounds to simulate real world conditions.
|
|
Polarised screen: A polarised screen option is available for Test Chart 2000 PRO. The screen is mounted in front of the monitor and polarises small areas of the screen in orthogonal directions. The patient views the screen through a polarised visor. This enables a range of binocular vision tests to be carried out (see below).
|
|
|
|
Polarised fixation disparity: This test is carried out in conjunction with the polarised screen. The two nonius markers are seen by the left and right eyes respectively while the rest of the screen is seen binocularly.
|
|
Polarised traffic lights: This test is carried out in conjunction with the polarised screen. Amber is seen binocularly while red and green are seen by the right and left eyes respectively. This provides a quick test for suppression.
|
|
|
|
Polarised binocular balancing: This test is carried out in conjunction with the polarised screen. The right eye see the letters at the top, the left eye see the letters at the bottom while the central letters are seen binocularly. Binocular balancing made simple!
