What is the name when blood partially fills the anterior chamber?

The term used when blood partially fills the anterior chamber of the eye is referred to as hyphema. This condition can result from trauma to the eye, which causes bleeding within the anterior chamber, the space between the cornea and the iris.

In cases of hyphema, the blood can accumulate in varying amounts, leading to symptoms such as vision changes and pain, depending on the extent of the bleeding. It's critical to recognize and address hyphema promptly to prevent potential complications, such as elevated intraocular pressure or permanent vision loss.

The other options provided do not apply to this specific condition. While hemorrhage is a general term for bleeding, it does not specify the location within the eye. Exudate refers to fluid that leaks from blood vessels due to inflammation and would not describe the presence of blood in the anterior chamber. Vitrectomy is a surgical procedure to remove the vitreous gel from the eye and is not related to the accumulation of blood in the anterior chamber. Understanding these distinctions is essential for proper diagnosis and treatment in ophthalmology.
