Psoriasis increases the risk of eye problems like uveitis. Uveitis is an inflammation of the inside of the eye, leading to eye pain, redness, blurred vision and sensitivity to light, and decreased vision.
1. Uveitis
Uveitis is an inflammation of the inside of the eye that can destroy eye tissue. This condition causes poor vision or blindness. There are many types of uveitis, depending on where the swelling is located such as:
Anterior uveitis is the most common, usually affecting the front of the eye Medial uveitis affecting the body Posterior uveitis affects the back of the eye If all the cells of the uvea are inflamed, it will lead to uveitis. The uvea is a primarily vascular anatomical structure, located between the sclera (the white part of the eye) and the retina (the innermost membrane formed by photoreceptors, light-sensitive cells). The uvea can be divided into three parts, respectively anterior-posterior:
Iris: The ring of pigment muscle tissue expands and contracts, acts like a diaphragm, regulating the diameter of the anterior foramen (pupillary) ); Biliary body: Composed of muscles, allowing the set of movements necessary to focus on the observed image (adaptation process); Choroid: Rich in blood vessels, it irradiates most tissues of the eyeball. The cause of uveitis is closely related to inflammation. For example, a toxic substance can get into the eye and cause inflammation. Uveitis can also be caused by an autoimmune disease, which means your body is attacking itself and causing inflammation, infections, and tumors in your eyes or other parts of your body, too.
