Subacute angle closure causes intermittent episodes of transiently elevated intraocular pressure. Headache is often the chief complaint, which may lead to misdiagnosis. The authors examined headache characteristics and consequences of delayed diagnosis. Patients presenting with headaches have a substantial delay in diagnosis, contributing to permanent ocular damage and glaucoma. Patients with subacute angle closure misdiagnosed with migraine are older and have shorter-duration headaches than patients with typical migraine.
Supported by a Heed Fellowship from the Heed Ophthalmic Foundation (K.S.S.).
The authors report no conflicts of interest.
