Retinal imaging may prevent vision loss
Scientists have developed a new non-invasive retinal imaging technique that can help prevent the onset of vision loss in diseases like glaucoma.

The group, led by David Williams from the University of Rochester, was able to distinguish individual retinal ganglion cells (RGCs) that bear most of the responsibility of relaying visual information to the brain. No one has successfully captured images of individual RGCs because they are perfectly transparent.

Glaucoma is currently diagnosed by assessing the thickness of the nerve fibres projecting from the RGCs to the brain. However, by the time retinal nerve fibre thickness changes, a patient may have lost 1,00,000 RGCs....
