Pupil abnormality

The pupil has a wide range of connections with various parts of the body. Its enlargement and contraction are affected by various factors, and its changes have important clinical significance. When the diameter of the pupil is larger than 5mm, and the dilation is continuous, the pupil is dilated. Pupils with a pupil diameter less than 2mm are said to have dilated pupils. Sometimes changes in the pupil can reflect certain lesions in the body, and some lesions in the nervous system can also be diagnosed based on changes in the pupil.
