Anisocoria - Symptoms, Causes, Risk Factors And Treatment

Aniscoria is a condition, in which the pupils are of an unequal size. The pupils may tend to dilate and constrict. In reality, it is the iris that moves. If the person has anisocoria, then the pupil tends to get larger and larger, and increasing the amount of light that enters the pupil. Anisocoria causes glaucoma, trauma to the eye or head, intracranial tumor or even infection of the membranes that surrounds the brain. It is also referred to as the Physiological Anisocoria. It is a benign condition.

Anisocoria Symptoms

The only visible symptom of Anisocoria is unequal sizes of the pupil. Apart from this, you will not notice any visible symptoms of this disease. Anisocoria Causes

The causes of anisocoria differ in seriousness from a Normal condition to a physiologic one, or one that is fatal. When a patient is suffering from anisocoria, there is a fear of a serious condition, as in intracranial aneurysm, which often compels the clinicians to obtain numerous tests. If the iris is absent, then Anisocora is the result of a defect in the efferent nervous pathways that controls the pupil. Sometimes, Aniscoria may also be caused by physical lesions or drugs, these may disrupt the pathways. The causes of this disorder are explained in detail below:

Parasympathetic Innervation failure

This causes dilation of the pupil, which causes them to react very sluggishly to direct light. Third Cranial Nerve damage.

This syndrome also causes Anisocoria. In this syndrome, the pupil is smaller than the other one, and both plans react briskly to light. The content of ptosis is mild.

Chemical Blockage

If by chance, there is a contact between the parasympathetic chemicals, and the conjunctiva, it will lead to the deactivation of the iris Sphincter muscle, and may result in the dilation of the pupil. It occurs mainly among the hospital personnel and all those people who are exposed to the atropine containing plants.

Adie's Pupil

This is another kind of anisocoria. It has similar symptoms which are already stated above. It is also caused by the damage of cranial nerve. The nerve fibers get degenerated due to viral infection. The symptoms of this disease are usually seen in case of women.

Iris Sphincter damage

Anisocoria is also caused due to the inflammation and trauma to the sphincter muscle. Anisocoria Risk Factors

There are certain people who are.

There are certain people who are More prone to anisocoria due to certain risk factors. Here are some of the risk factors:

Age - although there is no prediction for the occurrence of anisocoria, since anisocoria may occur at any age, / P>

Sex - No risk

Genetics or the Breed - There are certain breeds that are predisposed to the various causes of anisocoria. Of systemic illness. It may occur due to intrinsic eye problem or due to an underlying illness.

Anisocoea is relatively common in babies, although there is no particular age bar for this disease. But the babies who are born with different sized pupils may not have anisocoria. This can be a case of genetic disorder, and may not involve any anisocoria at all.

Intermittent Anisocoria

If the anisocoria is episodic, it may be intermittent. Simple anisocoria usually varies from week to week. Simple anisocoria is more frequent, and occurs in as many as 20% of the population. Anisocoria Differential Diagnosis Anisocoria Differential Diagnosis Anisocoria Differential Diagnosis Anisocoria Differential Diagnosis Anisocoria Differential Diagnosis This condition should be diagnosed in a proper manner, And for this, a number of tests needs to be performed. The differential diagnosis of this disease involves:

Adie's Syndrome Botulism Alcohol intoxication Cerebral Aneurysm Brain tumor Diabetes mellitus Encephalitis Herpes zoster Injury on the iris Iridocyclitis Ischemia Lead Poisoning Intracranial Hemmorage Multiple sclerosis Retinal Disease Tuberculosis Trauma Neoplastic Ocular prosthesis Syphilis Tapes Dorsalis Keratitis Degenerative Neurologic disorder Syringomyelia Aniridia

Some tests are recommended for the detection of this condition. It requires complete examination of the ophthalmic and neurologic area. After this, depending on the type of Anisocoria detected, the person has to undergo laboratory testing, electrodiagnostics, diagnostic imaging and pharmalogical testing. All these tests may be necessary to locate the underlining of the disease.

This condition is a benign one, therefore you do not have to worry much. But it may lead to problems in vision and may be due to infection in the eye and other ophthalmic troubles.

There are ceratin procedures that a person can follow for the treatment of this condition:
