What is the term for the presence of blood in the anterior chamber of the eye?

The term for the presence of blood in the anterior chamber of the eye is hyphema. This condition is characterized by the accumulation of blood in front of the cornea, beneath the clear tissue covering the front of the eye. Hyphema can occur as a result of trauma to the eye, surgery, or certain medical conditions, often leading to symptoms such as vision changes or pain.

In contrast, hypopyon refers to the presence of pus in the anterior chamber, typically indicating an infection or inflammation. Glaucoma is a group of eye conditions that damage the optic nerve, often associated with increased intraocular pressure, but it does not specifically describe the presence of blood. Retinal detachment involves the separation of the retina from the underlying tissue, which affects vision but is not related to blood in the anterior chamber. Each of these conditions has distinct characteristics and implications for treatment and management, making hyphema the appropriate term for blood in the anterior chamber.
