An Amsler grid, as seen by a person with normal vision. An Amsler grid as seen by a patient with OMD. Nearby color fills blind spots. Perception of traffic light in early-stage OMD if patient's line of sight is not directly at lit color Symptoms entail a loss of visual acuity in both eyes, including darkened vision, ring scotoma (ring of blindness close to the center of vision), color blindness, and difficulty with bright lights. The scotoma may cause text slightly away from the center of vision to disappear; the appearance would not be black (in early stages) but of the same color as the nearby background. Many lines of an Amsler grid would be faded or invisible to the patient. The area of invisibility on the Amsler grid spreads with time. Symptoms do not include headaches or eye pain. The loss of acuity tends to be symmetric between the eyes.
