Why is Facedown Recovery Essential
to the Healing Process
The
macula is the small part of the retina responsible for central
vision. A tear or hole in the macula impairs a person's
ability to see. Many activities, including reading and writing,
may become nearly impossible.
This condition, most prevalent among the elderly, arises
when the vitreous (the jelly-like substance which fills
the inner eye) becomes condensed and fibrous. The fibers
often bond to the macula, and when they shrink, they exert
a pulling force. A hole is opened
(see Figure 1), and the surrounding
tissue peels away from the eye, causing a loss of central
vision.
To repair the macular hole, the surgeon removes the vitreous
and replaces it with a gas bubble
(see Figure 2). The bubble
is meant to rise and apply pressure to the area in need
of healing. Since the macula is at the back of the
eye, the gas bubble will only aid healing if the patient
remains with their face down.
Pressure against the hole flattens the macula against the
wall of the eye (see Figure 3),
and the impaired visual area is helped to heal. During the
ensuing weeks, the afflicted eye will begin to heal, the
macula will re-bond to the eye wall, and as the gas bubble
is absorbed by the eye it will be replaced by the clear
vitreous fluid which your eye produces at all times .
Macular hole surgery is an easy, painless procedure with
a successful track record of improving or virtually restoring
vision. The real challenge for you while you're recovering
is dealing with the monotony, stress and discomfort of a
22-24 hour-a-day facedown postoperative position until the
gas bubble is absorbed--usually over a 2 to 6 week period.
