See retinal doc
You probably have had a diagnosis of an "abnormal spot" on your retina
by your ophthalmologist (you are seeing an ophthalmologist and not an optometrist
Something was seen (not too many bad things at age 34) and now given the large list of possiblities you need to have a diagnosis. If the person who found this is uncomfortable with a diagnosis, then get a referral to a retinal doc.
