A macular hole is a small break in the macula, the central part of the retina responsible for sharp vision. This condition can lead to blurred or distorted vision, making it difficult to read or recognize faces. It often occurs in older adults due to age-related changes in the eye. The exact cause of a macular hole is not always clear, but it can result from vitreous detachment, where the gel-like substance in the eye pulls away from the retina. Treatment options may include surgery to repair the hole, especially if vision loss is significant.
