The anterior chamber is the aqueous humor-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium. [1] Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. In hyphema, blood fills the anterior chamber as a result of a hemorrhage, most commonly after a blunt eye injury.
Symptoms include eye pain, eye redness, floaters and blurred vision, and ophthalmic examination may show dilated ciliary blood vessels and the presence of cells in the anterior chamber. Uveitis may arise spontaneously, have a genetic component, or be associated with an autoimmune disease or infection.
The eye is divided into a small front (anterior) segment, in front of the lens, and a large rear (posterior) segment, behind the lens. The anterior chamber is the light gray area at the top of this illustration. Hyphemas are frequently caused by injury, and may partially or completely block vision.
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 (i.e. the corneal endothelium) and the ...
The chafing of mispositioned intraocular lens over iris, ciliary body or iridocorneal angle cause elevated intraocular pressure (IOP) anterior uveitis and hyphema. It is most commonly caused by anterior chamber IOLs and sulcus IOLs but, the condition can be seen with any type of IOL, including posterior chamber lenses and cosmetic iris implants.
Because uveitic glaucoma is a progressive stage of anterior non infectious uveitis, uveitic glaucoma involves signs and symptoms of both glaucoma and uveitis.. Patients with acute non infectious anterior uveitis may experience the following symptoms: pain, blurry vision, headache, photophobia (discomfort or pain due to light exposure), or the observance of haloes around lights.

The retina is the innermost layer of the eye. The retina contains nerve cells responsible for sensing light and sending visual information to the brain. [6] The eye can also be divided into three chambers: Anterior chamber: (between the cornea and iris) Posterior chamber: (between the iris and lens) Vitreous chamber: (between the lens and ...
