- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors only looked back at scans from patients, so this is not yet a proven test.
The short version
A quick eye scan may help doctors tell when this lymphoma has reached the eye.
What was studied. Doctors looked back at eye scans from 36 patients with primary central nervous system lymphoma, 62 eyes in all. The scan, called OCTA, shows blood flow in the back of the eye.
What they found. 23 of the eyes had lymphoma in the eye. The other 39 did not. Eyes with lymphoma had less blood flow in one deep layer of the retina. Blood flow there was 45.92 percent in those eyes and 51.98 percent in the others.
What this means, and what it doesn't
What it could mean: Lymphoma in the eye is hard to find. This scan does not go inside the eye. It may one day help doctors check for eye problems along with other tests.
What it doesn't mean: This is not a treatment, and it is not a cure. The doctors only looked back at old scans at one hospital, and the group was small. The scan is just a possible test for now. It is not part of regular care, and it does not change how this lymphoma is treated.
