What do you mean, no pupillary reflex?

Pupil nonreflection means that the pupil can't contract and expand spontaneously. Pupil is a very important part of human eye tissue, which can adjust the amount of light entering the eyeball and adapt to the change of light intensity. Under normal circumstances, people's pupils will reflect according to the change of external light intensity, and the pupils will contract or expand to ensure the adaptability of the eyes to light. However, if the pupil does not reflect, it means that this adjustment function is lost, and the human eye cannot adapt to the change of light intensity, which is very unfavorable for protecting vision and eyeball health.

There are many reasons for pupil non-reflex, such as nervous system disease, eye tissue injury or disease, drug action and so on. For example, bilateral pupil abnormalities can be caused by nervous system diseases, while unilateral pupil abnormalities can be caused by eye or anterior tissue damage. In addition, some drugs can also affect pupillary reflex, such as cocaine, atropine, tramadol and other drugs can cause pupillary reflex, which needs attention.

If no pupil reflex is found, you need to see a doctor as soon as possible to find out the cause and carry out effective treatment. If it is caused by nervous system diseases, it needs to be examined and treated by nervous system, and if it is caused by eye tissue damage, it needs to be examined and treated by ophthalmology. For drug-induced pupillary non-reflex, the dosage of drugs should be increased or other drugs should be used under the guidance of doctors. In a word, pupil non-reflex is a manifestation of eye health problems, which needs people's attention and timely and effective medical intervention to ensure eye health.
