What disease is mydriasis seen in?

I believe many people know that a cat’s pupils can expand or shrink as the environment changes, and human pupils also have a light-sensitive effect. The size of the pupil will also change with changes in the environment. This way the pupil can adapt to the light intensity in a certain place so as not to cause irritation and damage to the eyes. Some people's pupils suddenly dilate. You begin to become less sensitive to external light. Let’s find out what disease mydriasis is.

In terms of the significance of life, pupil dilation is regarded by doctors as a sensitive indicator of vital functions. The pupil has extensive connections with many parts of the body. These multifaceted connections are realized through the nervous system. Changes in the pupil often indicate changes in certain physiological phenomena and pathological conditions. As we all know, the pupil will automatically shrink when the light is strong, and dilate when the light is dim - this is called the pupil's response to light. If the pupil's response to light becomes slow or absent, it means death is imminent. For comatose patients, their pupils will gradually dilate as their loss of consciousness worsens. Complete dilation is a sign of the end of life. Complete dilation of the pupil is a sign of the end of life. If it is just dilated, there is still hope of rescue.

The question of the cause of pupil dilation needs to be taken seriously . Here is the answer to the question: The pupil is a small round hole in the middle of the iris, surrounded by the iris. The iris in the eye is disc-shaped with a small round hole in the middle, which is what we call the pupil, also called the "pupil". Pupil dilation and contraction are mainly caused by the intensity of light. The pupil is like the aperture of a camera. It shrinks when the light is strong and enlarges when the light is weak. The pupil will shrink when it is in strong light for a long time, and it will enlarge when it is in weak light or in darkness.

Pupil dilation may also be caused by damage to the pupillary sphincter, which is called traumatic mydriasis. You should go to the hospital as soon as possible after the injury. The ocular surface may not look serious, but there is a high possibility of retinal concussion. Blurred vision may be caused by astigmatism caused by mydriasis, but the most likely cause is retinal concussion and macular edema.
