11.3.1 Headache attributed to acute angle-closure glaucomaHartmut Gobel2018-01-31T13:40:28+00:00
Description:
Headache, usually unilateral, caused by acute angle-closure glaucoma and associated with other symptoms and clinical signs of this disorder.
Diagnostic criteria:
- Any headache fulfilling criterion C
- Acute angle-closure glaucoma has been diagnosed, with proof of increased intraocular pressure
- Evidence of causation demonstrated by at least two of the following:
- headache has developed in temporal relation to the onset of the glaucoma
- headache has significantly worsened in parallel with progression of the glaucoma
- headache has significantly improved or resolved in parallel with improvement in or resolution of the glaucoma
- pain location includes the affected eye
- Not better accounted for by another ICHD-3 diagnosis.
Comments:
Acute angle-closure glaucoma generally causes eye and/or periorbital pain, visual acuity loss (blurring), conjunctival injection and oedema, nausea and vomiting.
When intraocular pressure rises above 30 mm Hg, the risk of permanent visual loss rises dramatically, which makes early diagnosis essential.
