Abstract

Imaging of chorodial features is possible through an undilated pupil, and without the use of dye by employing a new device which scans a laser line over the patients fundus to form real time video images. Further adjustments allow the device to produce images having fields of view from 60 to 15 degrees in width. Additionally, diode laser sources provide illumination wavelengths of 532, 635, 670, 690, and 820 nm. The combined functions of line scanning, adjustable focus depth in the z plane, and switchable illumination wavelength produce greyscale video images which clearly show detailed features of the patients choroid. In addition, the optic nerve head geometry is shown with very high resolution.
