Published in the journal Neurological Sciences, the study tested the eyes of 36 children aged 6 to 17 who had been previously diagnosed with autism along with a group of 24 typically developing children who served as controls. Yet, after 20 years of trying we still have not changed the average age of diagnosis here in the US, which is 4 years old.” “Intervening during that critical window could be the difference between a child acquiring verbal speech and staying nonverbal. “We know that when we intervene as early as ages 18 to 24 months it has a long-term impact on their outcomes,” says Lynch, who worked with children with autism while practicing as a speech-language pathologist. A staff member in Georgina Lynch’s lab demonstrates the use of a handheld monocular pupillometer to measure the pupillary light reflex. Such a tool would allow health care providers to catch children earlier in their development when interventions are more likely to benefit them. Floyd College of Medicine at Washington State University. The proof-of-concept study builds on earlier work to support the continued development of a portable technology that could provide a quick and easy way to screen children for autism, a disorder that affects communication and social interaction with others, says first author Georgina Lynch, an assistant professor in the Elson S. If you notice any difference in the pupil sizes or shapes, schedule an appointment with an eye doctor near you, so they can provide the correct diagnosis and help treat any underlying condition as soon as possible.Measuring how the eyes’ pupils change in response to light-known as the pupillary light reflex-could potentially be useful in screening young children for autism, according to a new study. If you notice differences in the sizes of your pupils, an eye doctor can help identify and treat the underlying cause of your condition. Wear protective eyewear while using heavy machinery.Wear a helmet while playing contact sports, horseback riding or cycling.Promptly report any changes to your vision to your doctor.To reduce your risk of developing uneven pupils: It’s possible to prevent anisocoria in some cases, especially if the pupil sizes are due to eye trauma. In some cases, if no pathology is discovered or uneven pupil size is temporary or considered to be normal, then the condition may not require treatment. If you have an abnormal growth, such as a brain tumor, referral to an oncologist will occur and medical treatments including chemotherapy or surgery might be recommended. If an infection is the cause, your eye doctor might prescribe antibiotic or antiviral eye drops. Your eye doctor will conduct a range of tests to determine the cause. Treatment will depend on the underlying cause of your anisocoria.

What symptoms commonly accompany anisocoria?ĭepending on the underlying cause of your anisocoria, you might develop other symptoms, such as: What causes anisocoria?Īnisocoria can result from a variety of causes. The iris muscles regulate the pupil’s size, making it larger in dim light and smaller in bright light.Īnisocoria is a symptom of several medical conditions, some of them very serious. Ordinarily, the pupils of the eyes are equal in size, and react equally to light and any change of focus. Up to 20% of the population is affected by unequal pupil sizes, known as anisocoria.Īnisocoria is an eye condition where the pupils, the black circles in the center of the iris, are different sizes.
