A new study provides the first clear evidence that vision or eye problems are rarely the cause of recurring headaches in children, even if the headaches usually strike while the child is doing schoolwork or other visual tasks.1 According to an AAO news release, many parents assume that frequent headaches mean their child needs glasses, so they ask their doctor to refer their child for an eye examination. This study was conducted by pediatric ophthalmologists who wanted to find reliable answers for parents, family doctors, and pediatricians facing this common health question.
In this retrospective study, which was conducted at the ophthalmology clinic of Albany Medical Center in New York, researchers reviewed the medical records of 158 children younger than 18 years who were seen at the clinic for frequent headaches from 2002 to 2011. All of the children received complete eye examinations by the clinic’s ophthalmologists.
No significant correlation was found between their frequent headaches and a need for vision correction, according to the news release. The researchers reached this conclusion by comparing the results of the clinic’s exams of the children with headaches to the records of their previous eye examinations and other relevant medical care. Ocular health and vision test results remained unchanged from earlier examinations for 75% of the children. Also, children who already had eyeglasses were not found to need new prescriptions at the time they were seen at the clinic for headaches. Although about 14% of the children reported that their headaches occurred while doing visual tasks like homework, and about 9% reported visual symptoms associated with their headaches, a need for vision correction did not appear to be the primary cause or a significant factor in any of these cases, according to the study.
The researchers considered it positive that most of the children’s headaches resolved over time. Follow-up reports from parents showed that headaches improved in 76.4% of all study subjects, including those who did and those who did not receive new vision correction prescriptions. Children who received new prescriptions were not more likely than others to have their headaches improve. Assessing the causes of the headaches and addressing the children’s long-term outcomes were beyond the scope of this study.
“We hope our study will help reassure parents that in most cases, their children’s headaches are not related to vision or eye problems and that most headaches will clear up in time,” said Zachary Roth, MD, who led the research team. “The information should also be useful to family doctors and pediatricians in caring for children and parents who have this common health concern.”
About 30% of the children in the study had eye conditions that went beyond the need for vision correction, including strabismus, amblyopia, or other rarer, more serious conditions. Seventeen percent had a family history of migraine. Because this was a retrospective study, the researchers were unable to connect these factors with headache causes.
