A macular hole is a gap that forms in the center of the retina, causing a blind spot in the middle of the vision.

The macula is the part of the retina responsible for central vision.  Due to natural forces on the surface of the retina, a hole can form in the very center of the vision causing the patient to see a missing spot in the central vision.  Most macular holes form spontaneously without any underlying risk factors.  A macula hole requires timely repair by a retina specialist to prevent a permanent blind spot.  Anyone experiencing a new spot of missing or blurry vision should seek a dilated exam with a retina specialist.
