To add some information, about 6 years ago, a had a macular pucker (which resolved spontaneously), and the
image I saw from the pucker looked similar to this
image, in fact I fully expected my ophthalmologist to say I had another one. Also, about 10-15 years ago I had an MRI that showed I had a slightly enlarged pituitary gland. Could pressure from the gland on my optic nerve cause this symptom?
