How can I have a Stage 4 macular hole yet have near perfect vision ?

[Monica19815]

At my annual opthamology exam, my doctor detected a hole in my right eye but said it was not full thickness and I had caught it early. The only symptom I had was a tiny bit of blurriness...nothing that interfered with daily life.  When I got to the retina specialist 3 weeks later she described it as a "tiny full thickness macular hole."  My vision was exactly as it was 3 weeks prior.  On the day of surgery...still very good vision as before.  At my post op appointment the day after surgery she told me it had been a Stage 4 hole.  How can that possibly be if my vision had been near perfect before the surgery??  Before the surgery the surgeon had said I would require to be face down for 3 days (difficult for me with neck issues) but that she would use a heavier gas and fill my eye more in case I could not do face down.  At the post-op appt. she said she wanted at least a week of face down from me (not possible).  I am befuddled at how diagnosis and post op instructions changed without any change in symptoms.  Any help understanding this would be appreciated.  I have to wonder of I chose the wrong surgeon.  (My opthamologist referred me and I trust him completely but now...I don't know.)

I can't explain that one. You can't have a full thickness macular hole and normal vision.

The only thing "abnormal" with my vision was that it had become a little blurry (street signs, cable TV guide) and I thought I just needed a low prescription contact lens or glasses.  Lines on a graph were only barely curved...nothing drastic.  Maybe she had me confused with another surgery patient at my post-op appointment.  I will question her about this next week.  Thank you for your reply.
