PeriData - Changes since version 3.7.0

Again we had many small changes and improvements. These are the most important.

New features

Single window opens automatically: When the visual fields are shown, the "Single Window" with the current (last) visual field opens together with the "Series Window". All with a single click !

Zoom easier: The keys CTRL and + (plus on the numeral block) or - (minus) will change the scale in 5-degree-steps. The zoom menu and the keys 1, 3, 6 and 9 (10,30,60,90 degree) are active as well.

Send patient data to the perimeter: This function has finished the BETA phase. In the option tab "Perimeter" you can choose the export option. At the perimeter device, the name appears automatically. This works with all Oculus and Octopus perimeters.

Window title shows more: If a perimeter interface is active for data import, the title of the program window shows the text "WAITING FOR DATA". In the LinkMode, the patient name is shown in the title.

Changes and improvements

New data pop up: After the import of new data, the database window pops up and the red cursor line shows the new examination.

Support routines improved: More log files are written. And the program messages are improved. This helps our support team to identify the origin of problems easier. In the last month we could see a considerable effect.

Device connection improved: The interface to the perimeter devices has improved, all device types are listed in particular. And the help texts were revised. The device connection is now running better and quicker.

Sort function has speeded up: Large databases (without Link Mode) are now sorted in a tenth of the time.

ONEPAT LinkMode: The commandline parameters /FIRSTNAME: and /NAME: may have arguments with spaces, if they are enclosed in quotation marks. Details see ONEPAT specs

Terminal-Server and Citrix-Server: The perimeter options are now stored to the user registry (instead of LocalMachine). If the file "PeriWin_Opt_Are_User_Specific.txt" exists in the standard "Exchange Directory", the options files PeriWin.opt and PeriRx.opt are not important any more, but only a backup. The server operation is easier to configurate and runs more stable.

Bug fixes

Special characters (Umlaut) and capitals: There were problems in some cases. Now even very seldom special characters in the patient name are treated correctly, and sorted logically. In the link mode, the Capitals and small letters are imported correctly.

Grayscale maps and color maps: In the case of irregular testpoint patterns (G1/G2 programm, some Oculus programs) had not always an ideal interpolation, defect zones could be elongated. Now the representations are rather realistic. Do not forget that interpolation is always an artefact.


Windows Versions: The installation with Windows XP and Windows 7 works now again. All operating systems up to Windows 11 are supported, with one exception: Windows 10-32bit was not modernized by Microsoft and blocks the installation of PeriData. If you need support, call the hotline.

Registry: The registry value HKEY_LOCAL_MACHINE \ SOFTWARE \ WOW3264Node \ PeriData \ PeriWin Shell \ Installation \ ProgramDirectory is not existing any more. The environmental variable %PeriDataProgDir% is preserved
