Blood flows nearly continuously back into the atrium, which acts as the receiving chamber, and from here through an opening into the left ventricle. Blood in the anterior chamber, or front chamber, of the cat's eye is a condition known as hyphema. The heart has four chambers, two upper atria, the receiving chambers, and two lower ventricles, the discharging chambers.The atria open into the ventricles via the atrioventricular valves, present in the atrioventricular septum.This distinction is visible also on the surface of the heart as the coronary sulcus. 04:00.

It then drains from the eyes anterior chamber through a structure called the drainage angle, which is located where the cornea and the peripheral part of the iris meet.

In cases of such spasm, any direct or bright light results in muscle contraction that worsens the eye pain. The anterior part of the uvea is the iris that surrounds the pupil and the adjacent ciliary body that synthesizes aqueous humor, the fluid that fills the front of the eye. Under a special microscope called a slit lamp, your ophthalmologist may be able to see white blood cells in the anterior chamber. The symptoms of hyphema are dependent on the extent of bleeding, whether vision has been impaired, and whether your cat has other systemic diseases.
