Uveitis

The uvea is the middle layer of the eye, located between the sclera and the retina.

The iris is the colored part of the eye that controls the size of the pupil.

The ciliary body secretes aqueous humor, a fluid that fills the anterior chamber of the eye.

The choroid is a highly vascular layer that provides nourishment to the retina.

Infection is the most common cause of uveitis, particularly in developing countries.

Ankylosing spondylitis is the autoimmune disorder most commonly associated with uveitis.

Anterior uveitis is the most common type of uveitis, affecting the front part of the eye.

The symptoms of anterior uveitis include redness, pain, blurred vision, and floaters.

The treatment for anterior uveitis includes antibiotic eye drops, steroid eye drops, and dilating eye drops.

The prognosis for anterior uveitis depends on the underlying cause.

Pars planitis is the most common type of intermediate uveitis, affecting the pars plana, a region of the eye between the ciliary body and the retina.

The symptoms of intermediate uveitis include floaters, blurred vision, pain, and redness.

The treatment for intermediate uveitis includes steroid eye drops, immunosuppressive drugs, and antibiotic eye drops.

The prognosis for intermediate uveitis depends on the underlying cause.

Choroiditis is the most common type of posterior uveitis, affecting the choroid, a layer of the eye that provides nourishment to the retina.

The symptoms of posterior uveitis include blurred vision, floaters, pain, and redness.

The treatment for posterior uveitis includes steroid eye drops, immunosuppressive drugs, and antibiotic eye drops.

The prognosis for posterior uveitis depends on the underlying cause.
