Sometimes a retinal hole develops in the center of the macula.
This is called a "macular hole" and is caused by vitreous
traction. The vitreous overlying the macula may first contract
and pull up the center of the macula. When this happens, the
patient may notice slight distortion or a reduction in vision.
As the vitreous continues to pull, the macula may develop a tiny
hole. With time, this hole may become larger. When a macular
hole occurs, central or detail vision is lost.
When a patient develops a macular hole in one eye, there is about
a 10% chance that a macular hole will develop in the the other
eye.
Once a macular hole develops, vitrectomy surgery may improve the
vision. The vitreous is removed and a gas is placed in the eye
that helps the macula to remain in place and the hole to heal.
Following the surgery, the patient is required to remain in a
face-down position for seven to ten days.
Not all patients with a macular hole will see better following the
surgery. Your doctor will discuss with you the indications for
and complications of the surgery. The complications are very
much the same as for any vitreous surgery
