A patient with a hyphema is examined by an ophthalmologist.

Definition

Noun: - Bleeding into the interior chamber of the eye: A medical condition where blood collects in the anterior chamber of the eye, which is the space between the cornea and the iris. This is typically the result of an injury.

Usage

• The term is used specifically in medical and clinical contexts to describe this particular type of ocular hemorrhage.
• It is a countable noun (e.g., , ).

Examples

• The patient presented with hyphema following blunt trauma to the eye.
• A traumatic hyphema requires immediate medical attention to prevent complications.
• The ophthalmologist monitored the resolution of the hyphema over several days.

Advanced Usage

• "Microhyphema": A related term referring to a very small amount of blood in the anterior chamber, often visible only under microscopic examination.
• "Total hyphema" or "eight-ball hyphema": A severe form where the anterior chamber is completely filled with blood, giving a dark red or black appearance.

Synonyms

Notes on Meaning

• The term refers exclusively to bleeding into the chamber of the eye. Bleeding in other parts of the eye, such as the vitreous humor (vitreous hemorrhage), is a different condition.
• It is almost always a sign of significant eye injury, though it can rarely occur spontaneously due to certain medical conditions.
