The macula is the portion of the central retina
responsible for our sharpest vision. A healthy and functioning macula is
necessary for reading, driving and recognizing faces and fine details. A macular
hole is not the same thing as macular degeneration. It does not involve scar
tissue, abnormal vessels or atrophy. Instead, it is a small round opening in the
retina located in the center of vision, the macula. This hole causes a blind
spot or missing spot in the central vision. Sometimes it may simply result in
blurring of vision or distortion of objects viewed.

Macular Hole
How are macular holes treated?
The only proven treatment for macular holes is
vitrectomy surgery. Vitrectomy is performed with small microsurgical instruments
that are inserted into the eye through small incisions. The vitreous humor
(natural gel-like substance that fills the eye cavity) is carefully removed,
along with any additional tissue coating the surface of the retina that may
prevent the hole from closing. A long-acting gas bubble is placed in the eye to
help the hole close, and the patient must maintain a face-down position for one
to two weeks to keep the bubble in contact with the macula. The bubble gradually
dissipates on its own. With surgery and strict face-down positioning, most holes
close, but the degree of visual improvement can be variable. In general, the
longer the hole has been present, the more variable the chances of visual
improvement. It is important to know that even though vitrectomy surgery can
repair the majority of macular holes, it can never restore vision to a
completely normal level.
