Functional aniseikonia (a. Functionalis) is a visual impairment that is characterized by changes in the shape and size of objects on the retina. This can be caused by various factors, such as eye diseases, injuries, age-related changes or disorders of the visual system.
Functional aniseikonia can manifest itself in the form of distortions in the shape and size of objects, as well as a deterioration in the clarity and contrast of the image. This may cause difficulty reading, writing, driving, and other activities that require good visibility.
To diagnose functional aniseikonia, special tests are used that allow one to assess the degree of visual impairment. Treatment may include vision correction with glasses or contact lenses, as well as surgery to correct eye defects.
Overall, aniseikonia functional is a serious visual impairment that can affect a person's quality of life. Therefore, it is important to promptly consult an ophthalmologist for diagnosis and treatment of this disease.
