Anisocoria

What is Anisocoria?

Anisocoria is when your eye's pupils are not the same size. The pupil allows light to enter the eye so that you can see. Anyone can have pupils that differ in size with no problems. In fact, one out of five people have pupils that are normally different sizes.

  • Eye pain.
  • Loss of vision.
  • Blurry vision.
  • Double vision (diplopia).
  • Light sensitivity.

Four out of five children with anisocoria (that is, the 80%) later suffered anisometropia and/or amblyopia, and, reciprocally, four out of eight children with anisometropia and/or amblyopia (50%) have previously presented anisocoria.

The causes of anisocoria are varied, and relate to alterations of the autonomic nervous system and/or the iris muscle. From the autonomic nerve standpoint, the parasympathetic system constricts the iris, whereas the anatomically distinct sympathetic channels dilate the iris.

The No. 1 way to prevent amblyopia is for your child to have regular well-child visits with a pediatrician on the schedule laid out by the American Academy of Pediatrics.

Presence of strabismus (p<0.0001), greater magnitude of significant refractive errors (myopia, hyperopia, astigmatism, and anisometropia, each p<0.00001) were independently associated with increased risk of unilateral amblyopia.

How is it diagnosed?

Anisocoria treatment is mostly focused on the underlying cause. For example, if a seizure caused uneven pupils, a treatment regimen to control seizures will likely be implemented. Treatment for anisocoria itself is usually not necessary.

How is it treated?

Treatment for acute myeloid leukemia is vital. It varies with the patient and stage of the disease. Treatment options include

The treatment of anisocoria depends on the underlying condition causing the condition. Most causes of anisocoria only require observation. A referral to a neuro-ophthalmologist, ophthalmologist, or neurologist may be warranted in cases that do not resolve
