What Causes a Macular Hole?
Age is the most common cause of macular hole. As you get older, the vitreous begins to shrink and pull away from the retina. Usually the vitreous pulls away with no problems. But sometimes the vitreous can stick to the retina. This causes the macula to stretch and a hole to form.
Sometimes a macular hole can form when the macula swells from other eye disease. Or it can be caused by an eye injury.
