Scanning laser ophthalmoscopy (SLO) is a widely used technique in ophthalmology for examining the interior of the eye. However, there are alternative synonyms that may also be used to refer to this type of technology. One of the most popular synonyms is confocal scanning laser ophthalmoscopy (CSLO), which is a variant of SLO that employs confocal microscopy for better image quality. Another synonym is laser scanning tomography (LST), which is a modification of SLO that uses tomography algorithms to produce three-dimensional images of the retina. Other possible synonyms include retinal laser scanning and fundus laser scanning. Regardless of the name, these techniques are vital for early detection and monitoring of eye diseases such as glaucoma and macular degeneration.
