OCT stands for Optical Coherence Tomography. Try saying that three times fast with a mouthful of biscuits. It’s basically an ultrasound, but using light instead of sound.
It takes a 3D picture of the back of your eye. We’re talking about the retina, the optic nerve, the whole nine yards. It’s like Google Maps for your eyeball’s insides.
It’s painless. No poking. No prodding. You just stare at a pretty little light for ten seconds. Even a grumpy cat could do it.
