Anisocoria Treatment in Wood Dale, IL

Anisocoria in Wood Dale, IL

Anisocoria is the medical term for pupils of two different sizes. Anisocoria can occur for many different reasons; in some cases it's harmless, and in others it may indicate a very serious eye health problem. Anisocoria is often associated with medical conditions such as Horner's syndrome or ocular nerve palsy. In these cases, treatment may be available.

Anisocoria Causes

The pupil is the black part of the eye surrounded by the colorful iris. Normally, the pupils in both eyes are identical. In certain cases, however, the pupil size is different in both eyes. This is known as anisocoria.

To understand the causes of anisocoria, it's important to discuss the different types of the condition. Types of anisocoria include:

  • Physiological anisocoria, where the pupils are different sizes inherently.
  • Mechanical anisocoria, where the pupils are different sizes due to injury, inflammation or surgery side-effects.
  • Horner's syndrome, in which anisocoria is one symptom of a potentially life-threatening condition in which the nerve trunk in the skull has become damaged.

The different types of anisocoria range from being medically insignificant to introducing a very serious health risk. If a person has had two different-sized pupils for his or her entire life without symptoms, it's likely not a significant medical issue. However, if the anisocoria is sudden, it's important to get medical help immediately.

Anisocoria Symptoms

The most prominent symptom of anisocoria is two differently sized pupils. In cases of physiological anisocoria, this difference in size is typically very small. Many people suffer from physiological anisocoria without realizing it, and the pupils may only vary in size by a single millimeter.

For mechanical anisocoria, the difference in size will be greater. Other symptoms of mechanical anisocoria include:

  • Inflammation
  • Eye pain
  • Reduced vision quality in one or both eyes

Anisocoria is most serious when associated with Horner's syndrome. In addition to two differently sized pupils, other symptoms of Horner's syndrome include:

  • Reduced pupil dilation when exposed to light
  • Drooping eyelids (ptosis)
  • Impaired vision
  • Dizziness
  • Headache
  • Neck pain
  • Weakness

Horner's syndrome anisocoria can be caused in many different ways, including nerve damage, stroke, brain tumors, genetic defects, migraines and certain cancers.

Anisocoria Treatment

For those suffering from physiological anisocoria or mechanical anisocoria, treatment is not necessary because they are not threatening to the person's health. In some cases, special contacts may eliminate or reduce the appearance of differently sized pupils.

For Horner's syndrome-related anisocoria, treatment focuses on addressing the underlying condition. Possible treatment options include:

  • Nerve surgery
  • Nerve conduction therapy
  • Migraine treatment
  • Brain tumor removal
  • Certain medications
