The spot to the left of the centre is the macula. The grey, more diffuse spot in the centre is a shadow artifact. The fundus of the eye is the interior surface of the eye opposite the lens and includes the retina, optic disc, macula, fovea, and posterior pole. [ 1] The fundus can be examined by ophthalmoscopy [ 1] and/or fundus photography .
Uvea with 14. Iris, 15. Ciliary body. The anterior segment or anterior cavity[ 1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [ 2][ 3] Within the anterior segment are two fluid-filled spaces: the anterior chamber between the posterior surface of the cornea ...

When an injury occurs, leaving skin exposed, it leaks out of the blood vessels and into nearby tissues. The fluid is composed of serum, fibrin, and leukocytes. Exudate may ooze from cuts or from ...
Corneal epithelium. Vertical section of human cornea from near the margin. (Waldeyer.) Magnified. The corneal epithelium ( epithelium corneae anterior layer) is made up of epithelial tissue and covers the front of the cornea. It acts as a barrier to protect the cornea, resisting the free flow of fluids from the tears, and prevents bacteria from ...

Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...
