Corneal perforation
Full-thickness defect in the cornea allowing communication between the anterior chamber and external environment.
Full Definition
Corneal perforation represents a full-thickness breach of corneal tissue, creating an open communication between the intraocular space and the external environment. This serious condition can result from infection, trauma, chemical injury, or complications of corneal surgery. Immediate signs include shallow or flat anterior chamber, positive Seidel test (aqueous leak), and potential iris prolapse. Emergency management includes protective shielding, immediate ophthalmologic consultation, and often urgent surgical repair. Documentation must record the size, location, and associated findings, along with immediate management steps and surgical intervention details.
Usage
Usage note: Always document size, location, and emergency measures taken for corneal perforations.
