Extended pupils - is it worth worrying?

Extended pupils are quite common in both children and adults. It is possible that the pupils may differ from one another during a certain period. If there are no worrying symptoms besides, there is nothing to worry about.

Congenital or acquired symptom - dilated pupils in the child - does not cause problems with visual acuity. However, for greater persuasiveness, it is better to consult an ophthalmologist.

The most common cause of dilated pupils in adults is the use of eye drops. Such changes do not have negative consequences.

There are also other reasons that provoke dilated pupils :

1. Aneurysm of the aorta.
2. Intracranial bleeding, triggered by trauma.
3. Development of a brain tumor.
4. The difference in pressure on the eyes (one more, another less). The cause of this, as a rule, is glaucoma.
5. Membrane infection, triggered by meningitis or encephalitis.
6. Constant and prolonged headaches.
7. Development of a lymph node tumor located in the upper region of the chest.
8. Taking medications (Atropine, Scopolamine, Gomatropin and Adrenaline).
9. Remember that one of the main factors affecting the size of the pupils is a powerful release of adrenaline into the blood. In general, dilated pupils are an indicator of the internal state of a person. It is for this reason that during the operation the doctors constantly monitor the condition of the pupils of the patient, in order to diagnose changes in time. When a patient is given a light anesthetic, his pupils are narrowed. If the anesthesia is deep, the pupils dilate.
10. Most likely, the known factor causing "big pupils" is the use of narcotic drugs, alcoholic drinks or hallucinogenic drugs. Remember that even if a person still refuses to take drugs, the pupils no longer acquire the former form and remain permanently extended.

In addition to medical indicators, there are natural causes of pupil dilations. This happens when changing lighting. In the dark, the pupil expands. If its diameter is about 3-5 mm at rest, its size increases by about one and a half times as a result of reaction to darkness or semi-darkness. At different ages the pupil reacts differently. The youth are more adapted to the darkness. In adulthood, the size of the icon decreases.

There is a disease when the dilatation of the pupils is a constant and stable phenomenon. This is due to a decrease in the ability of the optic nerve to respond to light changes. As a rule, patients who have such a disease have enlarged pupils under normal illumination. When the brightness of light rises, the eyes may begin to ache. Also, there are problems in the absence of light at all. Such patients need to be extremely cautious during movements at night. They can not see objects in full at night. This is especially dangerous for drivers.

The human body undergoes changes in connection with the influence of psychological factors. Eyes - not an exception in this case. When a student, for example, experiences a strong emotional tension as a result of an examination, an impending test, or an untrained occupation, his pupils expand. Also, the pupil expansion is observed as a side reaction to physical pain (sharp sharp pain).

When a person's emotional state is sad, sad, frustrated, the pupils, on the contrary, narrow. That is, emotions associated with a melancholic mood, cause a decrease in their size. A sharp burst of them - expansion.

In any case, if the cause of your condition is not known, it will be more appropriate to contact a specialist.
