Objective: Developing an Internet based interface for search and display of perimetric records on mobile wireless devices.
Methods: This study is based on a database with 3205 anonymous perimetric test sets of the Tuebingen Automated Perimeter (TAP). The 30° test grid of the central visual field contains 191 test locations with centripetal condensation. We developed a Java servlet, that runs on a webserver and processes Internet requests. It retrieves perimetric data sets from the database and generates device-dependent results. Using a web browser the request is submitted with an HTML form, the corresponding search result is sent back as an HTML table. For mobile wireless devices we developed a client software based on the Java 2 micro edition (J2me). The graphical user interface was designed to the restricted capabilities of mobile devices. The database can be accessed via an http connection, that enables wireless remote search e.g. from a mobile phone. The retrieved datasets can be stored permanently on the device, to make offline sessions possible.
Results: The application of Java technology on server- and client-side devices allows mobile wireless search and display of perimetric records.
Conclusions: This technology is the technical basis for applications in telemedicine in the fields of telediagnostics and teleconsultation. The current technical capabilities (display size, resolution) of mobile wireless devices are a heavy limitation. The transmission of personal data would require the implementation of user-dependent access control and the use of encrypted connections.
