Abstract

The Wilmer fundus camera stimulator has been designed to allow testing of visual function at precise retinal location under direct visualization. We use a modified fundus camera with a deep red source and IR vidicon to allow for both low levels of illumination and visualization of the fundus. The stimulus location is plotted directly on a real-time digitized image of the fundus using computer-generated graphics, and fixation can be monitored as testing proceeds. The fundus image with stimulus location can be stored on floppy disk for later retrieval and analysis. Both static and kinetic perimetry can be performed. This paper describes the fundus camera stimulator in detail, compares it to existing types of fundus perimeters, and provides clinical examples of its use.
