Anizocoria, or different pupil size

What is anisocoria

different pupil sizes Anisocoria is a special medical term, which means different sizes of pupils. For an adult, the difference within one millimeter is the absolute norm. The pupil of a different size in the child is not necessarily a sign of any disease and can be a simple consequence of a genetic predisposition. In the event that the patient does not have any other symptoms, then there is nothing to worry about. However, the presence of pupils that differ in size by more than one millimeter, especially when this condition progresses over time, may be a sign of the development of diseases of the blood vessels, brain or nerves.

Causes of the appearance of anisocoria

the pupil One of the main reasons for the appearance of this phenomenon, as the different size of the pupil, is the use of eye drops. In this case, this is a natural and harmless change in the ordinary state. Exactly the same phenomenon can be observed with accidental ingestion of drugs into the eyes, for example, when using

inhalers - preparations against asthma. In newborns of different sizes, the pupils can be the result of a trauma to the cervical region obtained during childbirth. Sudden and rapid development of anisocoria can occur with hemorrhage in the brain, the appearance of a tumor in the brain, encephalitis or meningitis. In addition, different sizes of pupils can be associated with an aneurysm, increased pressure in one eye, migraine, changes in the oculomotor nerve, carotid artery thrombosis or impaired cerebral circulation. In children, the unexpected appearance of different pupils can be triggered by any trauma( injury) or infection.

Diagnosis and treatment of anisocoria

different pupils in the child Professional diagnosis of a phenomenon such as anisocoria, involves the carrying out of a number of neurological and physical examinations in a specialized medical institution. Obligatory are the analysis of blood, computed tomography, examination of cerebrospinal fluid, tonometry( with suspicion of glaucoma), MRI, x-ray of the neck and skull. Treatment will depend wholly and entirely on the cause that caused the development of the unevenness of pupil sizes. Depending on the specific diagnosis, the doctor may prescribe corticosteroids, medications for migraines, painkillers, anticonvulsants, antitumor agents or antibiotics.

Anisocoria in children

In the case of determining anisocoria in a newborn, it is absolutely necessary to show the baby to the oculist and neurologist. If there are different pupils in a child younger than five to six months, then, as a rule, doctors do not prescribe any specific treatment. In the absence of adverse symptoms and any pathological changes in the behavior of the baby, wait-and-see tactics are recommended, aimed at studying the dynamics and monitoring the development of the baby. In the case of the appearance of anisocoria in older children, some treatment may be required.
