Purpose: : To develop and test a system for retinal oximetry based on scanning laser ophthalmoscopy (SLO).

Results: : The system successfully produced pseudocolor images showing oxygen saturation in retinal arterioles and venules (figure). In one eye mean retinal arteriolar oxygen saturation was 95% and the mean venular oxygen saturation was 66%. In another individual mean arteriolar oxygen saturation was measured 107% and the venular mean was 55%.

Conclusions: : It is technically possible to derive information on retinal vessel oxygen saturation from a scanning laser ophthalmoscope with two wavelength oximetry algorithm. Preliminary results are promising and suggest that scanning laser ophthalmoscopy may be used for retinal oximetry.
