i am writing a paper for my A & P class and our professor described a condition to us of a newborn infant. he wants us to tell him what conditions could account for the issues he described...not neccessarily to completely diagnose it. the only symptoms provided include that upon birth a newborn demonstrates normal spinal reflexes but upon pupil examination, the right eye responds properly but the left eye does not. upon a more thorough examination it is determined that the retina of the left eye is incomplete. it is also noted that the left eyes pupil sits medial and superiorly to the right eyes pupil. Could this be coloboma? It is a nervous system assignment so i am inclined to think more along the lines of cranial nerve damage, specifically the optic nerve - maybe optic nerve hypoplasia?
