RT Journal Article SR Electronic T1 Angle closure as a cause for intermittent headache in a child JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr-2017-219517 DO 10.1136/bcr-2017-219517 VO 2017 A1 Nuno Pinto Ferreira A1 Joana Medeiros Pinto A1 Filomena Pinto A1 Luis Abegão Pinto YR 2017 UL http://casereports.bmj.com/content/2017/bcr-2017-219517.abstract AB Angle closure is usually associated with older patients, as it typically manifests in middle to later life, being associated with an age-related increased lens volume. However, angle closure can occur in any age group if there is an anatomical predisposition that promotes pupillary block or an anterior pulling of the iris. During an acute angle closure, patients generally experience ocular pain, headache, nausea, vomiting and conjunctival hyperaemia. These attacks can be misinterpreted as migraine, particularly if subacute or chronic and the demographic characteristics of the patient do not suggest a primary angle closure event. Diagnosing a headache as ocular related is of paramount importance, since there is an effective treatment. We report a case of a child with intermittent headache which revealed a subacute angle closure in both eyes.
