Probing visual function with psychophysics and photochemistry

Eye (Lond). 1989:3 ( Pt 1):84-9. doi: 10.1038/eye.1989.12.


New methods using computer based measurements and image analysis techniques can improve and expand our ability to investigate non-invasively the function of the retina in patients. These can provide insight into the underlying mechanism of an abnormality and further our understanding of disease processes.
