Already, we have fundus image for retinal layer. similarly, is there technology available for getting fundus image for choroidal layer of an eye.
segmented and stacked OCT B-scans can give 3D rendering of choroid layer. But quantifying the vasculture is a difficult process, but when we have fundus image for choroid layer, it helps to quantize vasculature.
For imaging the choroid, larger wavelength lasers have to be used which can penetrate the retinal pigment epithelium efficiently.
The indocyanine green angiography gives a good detail of the choroidal vasculature.
A non-invasive way to capture choroid is 'red separation mode' in the Optos imaging system.
Also, newer OCT machines with enhanced depth imaging reveal choroidal structure nicely.
OCT angiography can demonstrate the intricate structure of different layers of choroids very beautifully.
