Some patients will notice abnormalities in central vision only when looking at a white wall. Dark or Black Spots on White Walls When Waking Up Patients with symptoms of retinal detachment should have an eye exam as soon as possible so that treatment can be given promptly. It is important to differentiate this from flashing lights in the side vision, which, when associated with new floaters or a “curtain” blocking the side vision, can be a sign of a different disease: retinal detachment. It can occur when new blood vessels or scar tissue is tugging on the retina. Patients have also complained of flashing lights in their central vision. The low-light vision may then return very slowly over about 30 minutes. For example, it would be more difficult to see the seats in a dark movie theatre immediately after coming in from the bright sunlight. One common symptom that’s harder to notice is that it takes longer to see in the dark, which is called delayed dark adaptation. This happens when the retina takes longer than usual to adapt when switching from a bright to a dark environment.
However, there are other symptoms of AMD that are less noticeable or occur less often, but that you should still know about. Or, if someone has advanced AMD, they may notice a dark area or distortion in their central vision. Learn about symptoms of macular degeneration that are often not as noticeable or occur less frequently.Īge-related macular degeneration is usually diagnosed during a routine eye exam when the eye doctor sees small white spots in the retina called drusen.
