Eye Pupil – Entrundete Pupillen

What causes pupils to be round?

Pupils are normally round. They may become dilated (larger) or constricted (smaller) in response to light, accommodation, and other stimuli. Certain conditions, such as Argyll Robertson pupils and Adie's tonic pupil, can cause pupils to be abnormally shaped or to react abnormally to light.

What does it mean if your pupils are round?

Round pupils are usually a sign of normal eye function. However, there are some conditions that can cause pupils to be abnormally shaped or to react abnormally to light. These conditions include:

• Argyll Robertson pupils: These pupils are small and irregular in shape. They do not react to light, but they do react to accommodation.
• Adie's tonic pupil: This pupil is large and dilated. It reacts slowly to light and accommodation.

What should you do if your pupils are round?

If you are concerned about the shape or reactivity of your pupils, it is important to see an eye doctor. They can determine if there is an underlying condition that is causing the problem and recommend the appropriate treatment.

Additional information

The shape of the pupil is controlled by the iris, which is the colored part of the eye. The iris contains muscles that can contract or relax to change the size of the pupil. The pupil is usually round because the muscles in the iris are evenly balanced.

In some cases, the muscles in the iris can become damaged or weakened. This can cause the pupil to become abnormally shaped or to react abnormally to light. Certain neurological conditions, such as Horner's syndrome and Parinaud's syndrome, can also affect the shape and reactivity of the pupils.
