In most cases, the patient will see a bright or flickering spot of light that blocks the vision without being too dark. This spot usually expands to cover a bigger area, thus blocking vision furthermore. However, the person will be able to see normally beyond the borders of that spot.

As the time goes by, the scotoma is more likely to grow in size. In the early stages, patients will be able to see objects more clearly by not looking at them directly. Tilting their faces or looking at one side of the object might prove to be more comfortable. In this way, the patient will be able to see more details of the object as they adjust the scotoma so that it doesn’t cover the object.

As the condition progresses, the scotoma can cover half the field of vision. The nature of the flickering can change as well. Some patients report seeing arcs or waves of bright light, while others can see different and more uncommon patterns. The color of the light can differ from bright white to other colors.

What are Causes?

The main cause behind scintillating scotoma without headache is a pattern of changes in the nerves of the brain. This condition is known as cortical spreading depression and is the most important cause of the scotoma. Migraines are usually caused by and can lead to hormonal imbalance. This, in turn, will interfere with the normal functions of this particular nerve in the body.

Cardiovascular diseases can also trigger scintillating scotoma without headache, and the associated symptoms can become very severe over time. High blood pressure is also one of the reasons that usually leads to the development of this condition.
