infarct of left superior cerebellar
artery-deficits?
lesion in area 4. Blood supply to area of lesion?
Where is the pons? Where is the thalamus?
Smart?
Lesion in area 17
Contralateral homonymous hemianopia
Progressive optic nerve damage (indicated by the cup
to disc ratio) caused by glaucoma. Notice the pale
appearance of the nerve with the 0.9 cup as compared
to the nerve with the 0.3 cup.-mechanisms of damage?---acuity? RAPD?
DOES THIS HELP?
