[Recording and analysis of the electrooculography using a personal computer. Initial experiences with normal probands and patients with diseases of the posterior eye segment and intraocular foreign bodies].
The electro-oculogram (EOG) is recorded by a personal computer and analyzed during the examination. If the results obtained with this method in normal subjects are compared with the conventional method (with which data recorded in analog form have to be measured manually), there is no significant difference. In patients with diseases of the posterior segment (e.g., posterior uveitis) or intraocular foreign bodies the results of computer and manual analysis are also practically identical. There are two computer analysis techniques: for subjects with almost normal EOGs the trigger-independent method is sufficiently accurate. In patients with pathologic EOGs, however, and in particular those with small potential differences, the trigger-related method is more likely to lead to correct results. The analysis path can be displayed on the computer monitor at any time, so that the examiner can always check whether it is correct. In contrast to manual analysis, the computer analysis cannot be influenced subjectively by the examiner. This considerably improves the comparability of examination results. A further advantage of computer analysis is its speed: the result is available immediately following the examination. It is a low-cost system which is easy to install and use, and thus suitable for routine clinical work.
