- angst_ridden 7y agoBut the retina is not exposed to the outside world. It's got the rest of the eye between it and the air.
- jessriedel 7y agoOk, but is brain tissue uniquely infectable compared to eye tissue or something? The ultimate worry isn't that your olfactory bulb gets hurt, it's that the infection reaches deeper into the brain, and I don't get why it's easier to do that from the olfactory bulb rather than from the eye.
