Temporary blind spots in both eyes.

I had my second occurance of this in the past year.  Noticed while reading that some letters were getting blocked out by a blurry spot that moved with the eyes.  No other noticable symptoms.  It was very disconcerting so I closed each eye separately, and noticed that the spot did not move, and was there for both eyes.  The spot was small at first and seemed to have a prismatic effect, although clear it blocked vision in the area.  Eventually, the spot started expanding, and disappeared in about 20-30 minutes.
After two days of thorough testing by the opthomologist, he found nothing.  His only guess was a possible optical migrain, with no pain, or possible TIA.  I'd be interested in what others might think.

Your symptoms sound very much like an ocular migraine, or acephalgic migraine (visual symptoms without the headache).  You have an expanding blind spot which moved ("migraine march") and then disappeared.  See your ophthalmologist again if the symptoms become very frequent or you start developing headache.  You should have a visual field exam, and might need an MRI-MRA if you develop very frequent episodes or bad headaches.

Thank you.  I believe I did have a visual field exam, along with a complete retinal check, as well as glaucoma, macular degeneration and cataracts among others....all of which proved moot.  Your analysis makes sense and parallels my doctors.  So far, I have only noticed these two episodes nine months apart.  Any more frequent than that I will see my doctor again.  BTW, I noticed one of the treatments for this condition is beta blockers, which I am already taking daily (for PVC), along with alpha blockers and Proscar for BPH.  Thanks again for your input.
