Superior Quadrantanopsia

Question:

Some time ago one eye was damaged after a seizure. Finally saw a neuro-op. The result was SQ in only one eye. Since a stroke had been ruled out what else would cause that damage?

Answer:

It is hard for me to know just why you have a superior quadrant defect in just one eye.  My first thought is that there may have been a blockage of a small blood vessel in that eye (e.g., a branch vein or branch artery occlusion).  A retina specialist may be able to determine if this occurred. 

If the vision loss is in just one eye, it is very unlikely that it is due to brain damage associated with the seizure since vision centers in the brain support vision for both eyes.
