corneal ulcer hypopyon Seidel positive urgent ophthalmology guideline
A positive Seidel test means aqueous fluid is leaking through a full-thickness corneal wound or perforation. This is an eye emergency, even if the infiltrate/ulcer is very small (for example <0.3 mm) and symptoms are mild.
The hypopyon also indicates significant intraocular inflammation or infection. Mild symptoms do not make this low risk.
Immediate action
- Arrange emergency ophthalmology assessment now, ideally in an emergency department with ophthalmology.
- Place a rigid eye shield only. Do not patch the eye or apply pressure.
- Do not rub the eye, remove any embedded object, or use contact lenses.
- Avoid checking intraocular pressure or doing further manipulation.
- Keep the person nil by mouth in case urgent surgery is needed.
- Bring any contact lenses, case, and current eye drops.
A positive Seidel test is considered definitive evidence of corneal perforation in the appropriate setting, per the AAO perforation guidance. A hypopyon with a corneal ulcer is a high-risk feature requiring urgent specialist treatment, and anterior-chamber inflammation can signal more severe infection according to the AAO corneal-ulcer guidance. The Wills Eye Manual states that a positive Seidel test indicates a full-thickness laceration.
If this describes you or a patient in front of you, go to emergency eye care immediately.
