In the early stages of VMT, many patients will not have symptoms. However, by the time a full-thickness macular hole has developed, most patients will be aware of reduced central vision and distortion when looking at words or people’s faces. Straight lines may also appear crooked, and you may also be aware of a blind spot in the middle of your vision. Occasionally, some patients may only notice these symptoms when covering their good, unaffected eye or at routine review by their optometrist. Conversely, some patients are aware of symptoms even when both eyes are open together (interference).
