<<<<homonymous hemianopsia>>>> - but what is it?
-- "anopsia" is blindness
-- "hemianopisa" is blindness in one-half the visual field, either the right (or left) half,
or perhaps the top (or bottom) half
-- "homonymous hemianopsia" is blindness in the _same_ half of the visual field in both eyes, (e.g. "right homonymous hemianopsia"). It is also possible to be unable to see the inner half of the visual field in both eyes.
The distinction can be helpful in localizing the part of the brain that is causing the blindness - right in front where the optic nerves are, say, as opposed to the back part which identifies the nerve impulses as images.

"anopsia" is blindness
Anu's example makes clear that the word can be used in the figurative sense, not just the strickly medical sense:
Odd then that with the proliferation of discourses surrounding the concept of "the postcolonial," so little attention should have been paid to a text ... There are, I think, three particular difficulties which may help account for that critical anopsia.
The metaphoric usage brings the word within tsuwm's wwftd preference for the "recondite word, especially one not falling into the following categories: medical terms ..."
