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.<\/jats:p>","DOI":"10.1136\/bcr-2017-219517","type":"journal-article","created":{"date-parts":[[2017,6,13]],"date-time":"2017-06-13T03:30:23Z","timestamp":1497324623000},"page":"bcr-2017-219517","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Angle closure as a cause for intermittent headache in a child"],"prefix":"10.1136","volume":"2017","author":[{"given":"Nuno","family":"Pinto Ferreira","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Hospital de Santa Maria, Lisbon, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joana","family":"Medeiros Pinto","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hospital de Santa Maria, Lisbon, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filomena","family":"Pinto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luis","family":"Abeg\u00e3o Pinto","sequence":"additional","affiliation":[{"name":"Visual Sciences Study Center, Faculty of Medicine of Lisbon University, Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,6,13]]},"reference":[{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.1","doi-asserted-by":"publisher","DOI":"10.1076\/soph.17.2.50.14718"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.2","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.2005.081224"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.3","doi-asserted-by":"crossref","first-page":"1109","DOI":"10.1212\/CON.0000000000000204","article-title":"The eye and headache","volume":"21","author":"Friedman","year":"2015","journal-title":"Continuum"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.4","doi-asserted-by":"crossref","first-page":"251","DOI":"10.1016\/S0002-9394(14)70797-4","article-title":"Angle-closure glaucoma in a 10-year-old girl","volume":"124","author":"Fivgas","year":"1997","journal-title":"Am J Ophthalmol"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.5","doi-asserted-by":"crossref","first-page":"997","DOI":"10.1016\/0002-9394(48)92533-1","article-title":"Acute glaucoma in an adolescent","volume":"31","author":"Boase","year":"1948","journal-title":"Am J Ophthalmol"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.6","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1971.03180150075020"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.7","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1971.01000010451017"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.8","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.51.11.783"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.9","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(03)00563-3"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.10","doi-asserted-by":"crossref","first-page":"419","DOI":"10.1111\/j.1755-3768.1958.tb00813.x","article-title":"Angle-closure glaucoma in an eye with a plateau type of iris","volume":"36","author":"T\u00f6rnquist","year":"1958","journal-title":"Acta Ophthalmol"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.11","first-page":"122","article-title":"Plateau iris syndrome","volume":"83","author":"Wand","year":"1977","journal-title":"Trans Sect Ophthalmol Am Acad Ophthalmol Otolaryngol"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.12","doi-asserted-by":"publisher","DOI":"10.1097\/00061198-199204000-00006"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.13","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-9071.2007.01510.x"},{"key":"2025082706504469000_2017.jun12_1.bcr-2017-219517.14","doi-asserted-by":"publisher","DOI":"10.1177\/0333102413485658"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2017-219517","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T13:50:54Z","timestamp":1756302654000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2017-219517"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,6,13]]},"references-count":14,"alternative-id":["10.1136\/bcr-2017-219517"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2017-219517","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2017,6,13]]}}}
