What Is a Macular Hole?
The macula is the central portion of the retina responsible for sharp, detailed vision. A macular hole develops when the tissue in this area stretches or separates enough to create an opening.
Most macular holes develop as the vitreous, the clear gel filling the eye, changes with age and pulls away from the retina. When the vitreous remains attached to the macula, that pulling can damage the delicate central tissue.
Macular holes are different from age-related macular degeneration, although both conditions can affect central vision.
