The retinal nerve fiber layer is the one part of the brain where nerve cells are not covered with the fat and protein sheathing called myelin, making this assessment specific for nerve damage as opposed to brain MRI changes, which reflect an array of different types of tissue processes in the brain.
An MRI brain scan can detect these small strokes.

In a recent study, researchers at Vanderbilt University used MRI imaging to monitor brain functioning in people engaged in more than one activity at a time.
After being rewarmed, babies at UCSF are given an MRI to look at brain structure and for evidence of degree of injury, and EEGs, which measure the brain's electrical activity and seizures.

In a 2009 study, scientists there used fMRI (Functional MRI) imaging to measure brain activity in regions of emotional processing in the brain before and after injecting Botox to suppress smiling muscles.
Throughout the 75-minute test participants were shown responses given by four other subjects, while the MRI machine snapped 1, 000 brain images.
But MRI has allowed us to visualize the brain's structures so we have a map in our head of where to go and where to avoid.
An MRI scan showed no problem with his brain activity and Quinn, as he is known to his friends, was sent for bypass surgery on Friday.
Dr. Wolinsky said the next study he expects to pursue will use functional MRI imaging to measure changes in the brain in people participating in cognitive-training exercises, he said.
To process the MRI data, a computer overlaid on Pickens' brain a virtual three-dimensional grid of 50, 000 cubes called voxels (a word hinting at volume and pixels).
Also, the brain begins shrinking relatively late in the progression of the disease, so MRI isn't as good at detecting the disease in its early stages when treatments are most effective.
That's an MRI scan of New York Times writer Matt Richtel's brain that was captured while he played a simple driving game -- all in the name of science (and journalism), of course.

On the other hand, the MRI images of women with normal libido showed activity in the entorhinal cortex, an area of the brain where positive emotions are registered.
Central to this project are advanced MRI scanning techniques, which the scientists say are able to pick up on details of the growing brain that have been difficult to capture until now.
BBC: Babies' brains to be mapped in the womb and after birth
Four different studies done in the past decade using MRI (magnetic resonance imaging) all found a slight reduction in the size of four regions of the brain: the corpus callosum, the basal ganglia, the frontal lobes, and the cerebellar vermis.
