Isn't there some condition where a person is unable to consciously "see" things, but their brain continues to process the information being recieved from the eyes and thus they operate as if they can see?

A phenomenon called Blindsight.
The person think it is blind (and is for most means),
If you ask him/her about the object in her blind field of view (often the blindness is onnly onesided) he/she will answer that he/she doesn´t see them.
But if you for example ask him//her to grab or touch a certain object wihthin the blind field of view, he/she will correctly do so (and will be unable to explain how he/she has done it).
The problem very pßrobably stems from a severation of neural connections to the visual association cortex, thus making the person unable to, as you already said, consciously see objects. But as the connections between the visual system and other parts of the brain (for example the motor cortex) are still intact, the person is still able to perform certain task that require visual input, as if she isn´t blind.
Oh and for the Thread Tpic:
