Summary
Definition
History and exam
Key diagnostic factors
- halos around lights
- aching eye or brow pain
- headache
- nausea, vomiting
- reduced visual acuity
- eye redness
- elevated intraocular pressure (IOP)
- corneal edema
- fixed dilated pupil
Other diagnostic factors
- use of medications that induce angle narrowing
- incidental eye findings
- blurred vision
- corneal hysteresis
- change in vision
Risk factors
- female sex
- hyperopia
- shallow peripheral anterior chamber
- second eye having angle closure
- Inuit and Asian ethnicity
- advanced age
- family history
- use of medications that induce angle narrowing
- corneal hysteresis
Diagnostic tests
1st tests to order
- gonioscopy, examination of anterior chamber angle
- slit lamp examination
- automatic static perimetry
Tests to consider
- ultrasound biomicroscopy
- anterior segment optical coherence tomography (of angle)
- evaluation of the optic nerve head by fundoscopy
- retinal optical coherence tomography
- Heidelberg retinal tomography
- GDx nerve fiber analyzer
Emerging tests
- corneal hysteresis
Treatment algorithm
initial presentation: acute angle-closure glaucoma
initial presentation: chronic angle-closure glaucoma
residual angle closure after laser peripheral iridotomy with elevated intraocular pressure
repeat episode of acute angle-closure glaucoma
