When a corneal foreign body presents alongside high-risk ocular findings — including blood or purulent fluid in the anterior chamber, or a dilated or non-reactive pupil — the clinical priority changes. These signs require immediate escalation rather than standard foreign body management.
This protocol covers corneal foreign body accompanied by one or more of the following: blood in the anterior chamber (hyphema), purulent fluid in the anterior chamber (hypopyon), a dilated, nonreactive, or irregular pupil, a corneal ulcer or infiltrate, significant visual loss in the affected eye, or signs or symptoms of penetrating eye injury or intraocular injury. Each of these findings raises serious concern for globe rupture.
When these high-risk findings are present, the management pathway involves urgent specialist referral as the critical first step — the complete structured protocol outlines what follows.

Pupils irregular or non-reactive? Significant visual loss? Hypopyon or hyphema? Corneal ulcer or infiltrate? Presence of intraocular injury?
Emergent ophthalmology referral is necessary in these cases to rule out an open globe rupture.
Evidence of frank blood in the anterior chamber (hyphema) or purulent fluid (hypopyon) also requires immediate ophthalmologic referral.
