Stereo Fundus Photos
Stereo Fundus Photos are specialized photographs in which the same structure is photographed twice but slightly offset to mimic the separation of our own eyes. This is done to simulate depth perception, so when the doctor reviews both photos using a specialize instrument they will be able to see the structure in question in 3D. This technique can be useful in monitoring certain conditions like glaucoma.
