Abstract
Maxwellian view and modulation control options for the scanning laser ophthalmoscope allow knowing, maintaining and systematically varying the entrance location of the Maxwellian view used for imaging or functional testing of a particular retinal test location. The scanning laser ophthalmoscope simultaneously images for subsequent digital image processing the anterior and posterior segment of the eye by using a second Newtonian imaging device or by repositioning the entrance location of the Maxwellian view in such way that vignetting of the anatomical pupil occurs. In the second method, the fixation target is systematically moved within the visible border of the anatomical pupil in order to use another entrance location of the Maxwellian view for a given retinal test location. The main advantages are simplicity of utility and the fact that the scanning laser ophthalmoscope no longer has to move in order to select or maintain a particular entrance location of the Maxwellian view for a given retinal test location.
