A macular hole is a small break in the macula, the part of your eye responsible for detailed, central vision.
The macula is a very small area at the center of the retina — a thin layer of light-sensitive tissue that lines the back of the eye. Light rays are focused onto the retina, where they are transmitted to the brain and interpreted as the images you see. It is the macula that is responsible for your pinpoint vision, allowing you to read, sew or recognize a face.
As we grow older, the thick vitreous gel in the middle of our eyes shrinks and pulls away from the macula. If the gel sticks to the macula and doesn’t pull away, the macular tissue stretches and eventually tears, forming a hole.
