Abstract
Reduced oxygen supply
to retinal neurons in the eye may lead to hypoxia, which may further cause retinal
edema, neovascularization, and other retinal diseases such as glaucoma and
macular degeneration. It is therefore important to assess retinal oxygen
levels. Retinal oximetry involves detecting the reflection of the incident
light that passes through the blood vessel, but it is challenging since the light
detected could come from several sources and reflections. FIU inventors
have developed a method to detect retinal blood-oxygen saturation levels using retinal
autofluorescence. In this method, one or more excitation sources are used to
provide light to the retina, and based on the intensity of the retinal autofluorescence,
the level of oxygen saturation is measured.
Benefit
· Accurate retinal oxygen saturation measurements · Non-invasive method
Market Application
The method has applications in clinical measurement and monitoring of the retinal blood oxygen saturation levels.
