If you notice that your pupils are unequal in size, see a doctor right away. Some experts note that the reinnervation can be segmental, irregular, and slow, which is correlated to how the symptoms of this condition occur. This allows for a better chance at recovery of innervation to the controlling function of the lens compared to pupillary reactive function recovery. Each of the ciliary ganglion has various dedicated fibers. This is more likely if the damage that occurred affected the ciliary body instead of the ciliary ganglion.

It is possible to experience partial function recovery if full recovery does not occur. Some people never experience full recovery of their pupillary response. In some cases, the pupil that was once larger actually goes in the opposite direction and becomes smaller than the other pupil. Within two years, approximately 50 percent of people with anisocoria experience a full recovery. For many cases of this condition, there is no known effective treatment. There is not a treatment specific to Horner’s syndrome. If an underlying cause is identified, treatment is aimed at this issue. However, the cause is not always identified. Most cases of this syndrome have an underlying cause, such as a tumor, stroke, or spinal cord injury.
It is characterized by a triad of symptoms, including pupil constriction that causes anisocoria, drooping eyelid, and not sweating in the area surrounding the affected eye. Horner’s syndrome is another possible cause of anisocoria. Certain medications that go directly into the eye, such as glaucoma eyedrops like pilocarpine.Eye trauma from accidental injury or surgery.Certain brain disorders and injuries, such as a stroke, brain tumor, brain hemorrhage, or infection in the brain.When the issue is significant, multiple factors can cause it.
Some research suggests that mild anisocoria affects about 20 percent of the general population. In many cases, when this issue is mild, there is no underlying cause. Over time, it is possible for both of the pupils to be affected. When Adie syndrome is present, it usually starts by affecting one pupil. Facial pain, headache, and emotional fluctuations are also possible with this condition. When a doctor tests the person’s deep tendon reflexes using a small hammer, they either do not have any response or the response is poor. When this issue occurs as a result of Adie syndrome, people often have poor or absent deep tendon reflexes too. Some examples of accompanying symptoms include the following: The underlying cause of this condition ultimately determines the other symptoms that a person experiences. But people can experience it on a regular basis too. In some cases, this condition is only temporary. The doctor usually picks up on the problem when they are giving an eye examination. In many cases, people do not notice that their pupils are unequal because the size difference is not significant. This means that it starts losing its color and can become lighter. It is also possible for the iris to experience depigmentation. This is referred to as anisocoria.īy looking at the affected pupil, you can sometimes see that it is larger than the other pupil. But for some people, the pupils are not always the same size. For most people, the pupils react to light, either enlarging or shrinking equally. The black spot in the center of your eye is known as the pupil. A doctor will perform an examination to determine if treatment is necessary.

While it is often a benign issue, it is also possible for it to be a symptom of a medical condition. In fact, it happens in about one in five people. It’s common to have pupils that are different sizes. Implantable Miniature Telescope SurgeryĪnisocoria, also called Adie’s tonic pupil or Adie syndrome, is described as uneven pupil size.
