Differentials of Unilateral Central Scotoma

Hey, guys this post will be on the differential diagnosis of "Blurred Vision in one eye" due to a central scotoma.

So a central scotoma can be usually due to retrobulbar neuritis(inflammation of the optic nerve) or optic nerve compression.

Now when you have detected a central scotomata in one eye it is essential to do the confrontation test in the other eye also. If in the other eye you detect a defect in upper temporal field, a superior temporal quandrantonopia; it is higly likely that this is a case of optic nerve compression.

How so? Well refer the attached pic with the illustrated diagram and I am sure you will understand. :)
