ABSTRACT
The quality of light is what makes a good image an even better image. The traditional fundus camera is like the soft box used in portrait photography. The light, or flash, that comes out of the fundus camera is very diffuse and fills in the detail of retinal pathology. Scanning laser ophthalmoscope (SLO) and confocal scanning laser ophthalmoscope (cSLO) systems have very sharp and focused light sources that enhance contrast and detail and suppress out-of-focus light. These light sources and the versatility of these instruments make them excellent diagnostic tools. They also suppress noise and can be combined with other modalities, like optical coherence tomography.
