Case history
Case history #1
A 50-year-old woman, who has no eye symptoms, is found during routine ophthalmic examination to have elevated intraocular pressure of 42 mmHg in both eyes. Funduscopy shows that the optic nerve head appears normal, with no evidence of glaucomatous neuropathy. Gonioscopy shows that the anterior chamber angles are closed for almost the full circumference.
Case history #2
A 64-year-old woman presents to the emergency department with severe pain around her right eye of 4-hour duration, accompanied by blurred vision in that eye. She is also nauseated. Examination shows a red right eye with oedematous cornea and a wide pupil that is unresponsive to light. Intra-ocular pressure is extremely elevated (60 mmHg), only in the right eye. The anterior chamber angle is closed in both eyes.
Other presentations
Patients may present with spontaneously resolving symptoms of intermittent ache and/or blurred vision with haloes around lights seen from one eye. Patients may also notice a change in vision, which may represent long-standing chronic progressive visual field loss.
