Retinal Imager

Background
Retinal image maps that can identify ischemic areas can have a significant application in the diagnosis and management of diseases such as diabetic retinopathy, macular degeneration and glaucoma. Oxygenated and deoxygenated hemoglobin have different absorption spectrum in the infrared. By selecting appropriate wavelengths of light the ratio of oxygenated to deoxygenated hemoglobin can be measured throughout the retina and areas that are not receiving adequate oxygen (ischemic) identified.


Description of Invention
The retinal imager being developed is in the form of a module that attaches to either a fundus camera (a camera that photographs the retina) or to a scanning laser opthalmoscope that provides topographic detail of retinal structures. Both of these devices are in wide use in clinical ophthalmology.


Advantages
This non-invasive device will allow for early detection and improved treatment of serious common eye diseases such as macular degeneration, diabetic retinopathy and glaucoma. It will also enable better ongoing management of these conditions by providing more sensitive measures of disease progression than are currently available.


Business Opportunity
A laboratory prototype is being developed and partners are sought to assist in the commercialization.
