Visual disturbance
Visual disturbance refers to changes or abnormalities in vision. Symptoms may appear, for example, as blurred vision, double vision, reduced sharpness, missing areas in the visual field, flashes of light, or darkened areas of vision. Visual disturbance may occur suddenly or develop slowly. In some cases, it is also associated with headache, eye strain, or dizziness.
The most common causes of visual disturbances in Finland are the need for glasses or contact lenses, presbyopia, eye strain, for example after prolonged reading, and eye diseases such as cataract, glaucoma, or retinal changes. Head injuries, migraine, diabetes, or certain poisonings (such as carbon monoxide poisoning) can also cause visual disturbances.
Not all visual disturbances are dangerous, but a sudden, clearly unusual, or rapidly progressing visual disturbance is always a reason to seek prompt assessment by a healthcare professional. Prolonged or recurrent visual disturbance also requires investigation. Sometimes the cause of changes in vision may be a more serious illness, and early recognition can help prevent worsening vision.

When is a visual disturbance a sign of a serious illness?
