Quick answer
How should I present an acute angle-closure glaucoma case on rounds?
Lead with the sudden eye pain, rainbow halos, and nausea in a dark environment, since that triad and trigger are classic. Give the exam findings and the exact intraocular pressure before naming acute angle-closure glaucoma. End with the specific topical-then-systemic pressure-lowering sequence and the urgent need for laser iridotomy.
Before you speak
Define the moment and the information you actually have
An emergency-department presentation immediately after intraocular pressure and gonioscopy are measured.
The emergency team and on-call ophthalmology deciding on the pressure-lowering sequence.
History, vital signs, a focused eye exam, intraocular pressure, and gonioscopy. Visual acuity testing is not itemized.
About 75 seconds
Fictional training case: The presentation is locked to the simulated patient JSON. It names important unknowns instead of inventing an examination, vital signs, allergies, or tests.
Complete spoken example
First, read it once without stopping
The paragraph breaks show the clinical shape. In a real presentation, pause briefly between ideas rather than announcing the headings.
Mr. Adams is a 64-year-old man with farsightedness who developed sudden, severe right eye pain, headache, nausea, and rainbow halos around lights after entering a darkened movie theater.
His vision in the affected eye dropped to blurred shapes, and he had associated nausea and vomiting; he initially thought this might be a migraine or food poisoning.
He has hyperopia, or farsightedness, and mild cataracts, and is a retired non-smoking teacher.
His vitals show a heart rate of 108 and blood pressure 154 over 92. His right eye shows conjunctival injection, a cloudy and steamy cornea, and a mid-dilated, fixed pupil, with the globe feeling rock-hard on palpation. Intraocular pressure measures 64 in the right eye compared to 16 in the left, against a normal range of about 10 to 21, and gonioscopy confirms complete 360-degree angle closure on the right with a narrow angle on the left.
My diagnosis is acute primary angle-closure glaucoma of the right eye, with critically elevated intraocular pressure, and the left eye also has a narrow occludable angle that will need its own preventive evaluation.
I am starting topical pressure-lowering drops immediately, followed by systemic acetazolamide and mannitol if the pressure does not fall adequately, and will add a miotic agent once the pressure decreases and the cornea clears enough for it to work effectively. I am obtaining urgent ophthalmology consultation for definitive laser iridotomy within 24 hours, and this will also need to be considered for the fellow eye.
Build the presentation
Give every sentence one job
A presentation is a compressed clinical argument, not a chart read aloud. These six moves keep the facts connected to your reasoning.
Opening one-liner
Name the triad and its trigger
“Mr. Adams is a 64-year-old man with farsightedness who developed sudden, severe right eye pain, headache, nausea, and rainbow halos around lights after entering a darkened movie theater.”
Why it belongs: Naming the specific trigger of entering a dark environment alongside the pain, headache, and rainbow halos is what should immediately raise angle-closure glaucoma over a migraine or gastrointestinal illness.
This is a 64-year-old with a bad headache and eye pain.
He developed sudden severe eye pain, headache, nausea, and rainbow halos after entering a darkened theater.
Why: Naming the dark-environment trigger and rainbow halos together is far more specific than 'headache and eye pain.'
History of present illness
Give the specific visual and systemic symptoms
“His vision in the affected eye dropped to blurred shapes, and he had associated nausea and vomiting; he initially thought this might be a migraine or food poisoning.”
Why it belongs: A sudden significant vision drop together with systemic nausea and vomiting is more specific for an acute ocular emergency than a typical migraine.
His vision got blurry and he felt sick.
His vision dropped to blurred shapes, with associated nausea and vomiting.
Why: Naming the degree of vision change is more clinically useful than 'blurry.'
Relevant background
Name the specific anatomic risk factor
“He has hyperopia, or farsightedness, and mild cataracts, and is a retired non-smoking teacher.”
Why it belongs: Hyperopic eyes tend to have shallower anterior chambers, which is the specific anatomic risk factor that predisposes to angle closure, especially in dim light when the pupil dilates.
He's farsighted.
He has hyperopia, which predisposes to a shallow anterior chamber and angle closure, especially in dim light.
Why: Explaining why the farsightedness matters is more useful than naming it alone.
Objective data
State vitals, the eye exam, and the measured pressure
“His vitals show a heart rate of 108 and blood pressure 154 over 92. His right eye shows conjunctival injection, a cloudy and steamy cornea, and a mid-dilated, fixed pupil, with the globe feeling rock-hard on palpation. Intraocular pressure measures 64 in the right eye compared to 16 in the left, against a normal range of about 10 to 21, and gonioscopy confirms complete 360-degree angle closure on the right with a narrow angle on the left.”
Why it belongs: The markedly elevated intraocular pressure and confirmed angle closure on gonioscopy are the objective findings that establish both the diagnosis and its severity, and the narrow angle in the fellow eye flags a future risk that needs its own follow-up.
His eye pressure was very high.
Intraocular pressure is 64 in the right eye compared to 16 in the left, with complete angle closure confirmed on gonioscopy.
Why: Naming the exact pressure in both eyes lets the listener judge severity and urgency precisely.
Assessment
Commit to the diagnosis and flag the fellow eye
“My diagnosis is acute primary angle-closure glaucoma of the right eye, with critically elevated intraocular pressure, and the left eye also has a narrow occludable angle that will need its own preventive evaluation.”
Why it belongs: Naming the fellow eye's risk in the assessment, not just treating the affected eye in isolation, reflects the bilateral anatomic nature of this condition.
He has acute glaucoma in his right eye.
This is acute angle-closure glaucoma of the right eye, and the left eye's narrow angle will also need preventive evaluation.
Why: Naming the fellow-eye risk shows more complete clinical reasoning.
Plan
State the specific pressure-lowering sequence
“I am starting topical pressure-lowering drops immediately, followed by systemic acetazolamide and mannitol if the pressure does not fall adequately, and will add a miotic agent once the pressure decreases and the cornea clears enough for it to work effectively. I am obtaining urgent ophthalmology consultation for definitive laser iridotomy within 24 hours, and this will also need to be considered for the fellow eye.”
Why it belongs: Naming the correct sequence, topical drops first, then systemic agents, then a miotic once the cornea clears, reflects the actual physiology of why a miotic given too early would not work well through a steamy cornea.
I'll give some eye drops and call ophthalmology.
I am starting topical drops, followed by systemic agents if needed, then a miotic once the pressure and cornea improve, with urgent ophthalmology for laser iridotomy.
Why: Naming the specific sequence shows understanding of why the order of treatment matters.
Do not fill the blanks
Say what has not yet been established
Real presentations often happen before the chart is complete. A brief, explicit limitation is safer and more credible than a polished invention.
Formal visual acuity testing
Say: “Formal visual acuity measurement is not documented in this simulation beyond 'blurred shapes,' and I would obtain it to establish a baseline and track response to treatment.”
A quantified baseline is needed to know whether vision is improving with pressure reduction.
Optic nerve and visual field assessment
Say: “A formal optic nerve exam and visual field testing are not part of this simulation and would be pursued once the acute pressure is controlled.”
These assess for any lasting glaucomatous damage from the acute pressure spike.
Clinical compression
What leads, what stays, and what can wait?
| Source detail | Decision | Reason |
|---|---|---|
| Sudden eye pain, rainbow halos, and nausea after entering a dark theater | Lead | This triad and the specific dark-environment trigger are the classic presenting features. |
| Vision dropped to blurred shapes | Include | It quantifies the severity of visual impairment at presentation. |
| Retired teacher, non-smoker | Omit | Occupation does not change the emergency management. |
| Intraocular pressure of 64 versus 16 in the fellow eye | Lead | This is the decisive objective finding confirming both the diagnosis and its severity. |
| Narrow occludable angle in the left eye | Include | It flags a real future risk that needs its own preventive evaluation, not just treatment of the affected eye. |
After the presentation
Likely attending questions
Answer the question first, then give the evidence. If the source case does not contain the answer, say what you would verify.
Why not give the miotic drop right away?
A miotic like pilocarpine works by pulling the iris away from the drainage angle, but it does not work well when the pressure is very high and the iris sphincter is ischemic, and it can be added once the pressure starts to fall and the cornea clears enough for it to be effective.
Why does the other eye matter if it isn't symptomatic?
A narrow occludable angle in the fellow eye carries a significant future risk of the same emergency, so it needs its own follow-up evaluation and often prophylactic laser iridotomy, even though it is asymptomatic right now.
Is laser iridotomy the same as the acute treatment?
No, laser iridotomy is the definitive treatment that prevents recurrence by creating a new drainage pathway, while the topical and systemic medications are used first to acutely lower the dangerously high pressure and protect the eye until the iridotomy can be performed.
Self-check
A 30-second check before you present
- Name the pain, halos, and dark-environment trigger together in the opening sentence.
- State the specific eye exam findings, including pupil shape and corneal appearance.
- Give the exact intraocular pressure in both eyes.
- Name the gonioscopy finding, not just 'high pressure.'
- State the correct treatment sequence: topical, then systemic, then miotic.
- Flag the fellow eye's risk explicitly.
- State the urgency and timeframe for laser iridotomy.
- Note what visual acuity or optic nerve assessment is still needed.
Common presentation problems
Repair the habits that make a case hard to follow
Calling this a migraine because of the headache and nausea
Repair: State the rainbow halos and eye findings that distinguish this from a primary headache disorder.
Giving a miotic drop as the first treatment
Repair: State that topical non-miotic agents come first, with a miotic added once pressure and cornea improve.
Ignoring the fellow eye's narrow angle
Repair: State that it needs its own preventive evaluation and likely prophylactic treatment.
Reporting 'high eye pressure' without exact numbers
Repair: State the exact pressure in both eyes for comparison.
Frequently asked questions
Oral case presentation questions
Should I mention anterior chamber depth measurement?
You can mention it as part of the ophthalmologic workup, but gonioscopy confirming angle closure and the measured intraocular pressure are the two findings that matter most for this presentation.
Do I need to explain why dark rooms trigger this?
Yes, briefly: pupil dilation in dim light can push the peripheral iris into the drainage angle in an eye with a predisposing shallow anterior chamber, precipitating the acute attack.
How long should this presentation be?
This worked example targets about 75 seconds. A patient with very severe pain and vomiting might need a more urgent initial framing focused on the pressure emergency.
