   most books i've refered state that the blind spot is median and lateral to the fovea...isn't this wrong?
   the fovea is the posterior pole itself then the blind spot cant be median ..
   and also is the blind spot a bit above or a bit below the posterior pole??

   Recall that the actual image formed on the retina is inverted. The visual cortex "processes" that image as far as "erecting" it.

   Physically, the blind spot is medial to the fovea but the image reversal caused by cornea and lens makes it appear lateral to the fovea then.
