The optical set-up of this device is reprinted in Fig. Light from the retina, was directly connected to the input channel of a television tube monitor. HeNe-laser for the red wavelength range) to generate a fast “flying” laser spot on the subjects retina and secondly, the amplified output voltage of the photomultiplier, which was used to detect the back-scattered

They named their instrument “flying spot TV ophthalmoscope” since firstly, they used a scanned beam of an ArKr-laser In a paper by Webb, Hughes and Pomerantzeff. Confocal scanning laser ophthalmoscope (cSLO)Ģ0 years after Theodore Maiman announced in New York in a press conference the invention of the laser, the first laser scanning ophthalmoscope, was demonstrated.Finally, an introduction to quantitative autofluorescence (qAF) is given, a new research tool, which is used to measure the accumulation of lipofuscin within the retinal pigment epithelium (RPE) for normal subjects and for patients with macular dystrophies. First, the assessment of the optic nerve head for glaucoma diagnostic by means of laser scanning tomography is presented, before in the third section the clinical aspect of wide field SLO angiography is discussed. In the following sections the focus is directed on one distinct clinical application for each of the major imaging modalities: reflectance, angiography and autofluorescence. This chapter gives an introduction to the history of SLO technology and a general overview on its clinical applications.

for the visualization of the vascular system after intravenously injecting an appropriate dye, as well as for autofluorescence imaging of endogenous fluorophores within the retina. Fluorescence imaging channels with different excitation wavelengths were introduced to SLOs for angiography, i.e. But also the reflectance modality itself has several important diagnostic applications: laser scanning tomography (SLT), imaging with different laser wavelengths (Multicolor contrast) and others. Reflectance imaging, where the back scattered light is detected, is widely used for eye tracking and as reference image for OCT applications.

Since the first scanning laser ophthalmoscope (SLO) was introduced in the early 1980s, this imaging technique has been adapted and optimized for various clinical applications based on different contrast mechanism.
