Uveitis is an ocular condition consisting of swelling and irritation in the middle layer of the eye or the uvea. It is this middle area of the eye which provides the majority of the blood supply to the retina. When the uvea becomes inflamed, symptoms including pain in the eye, redness, blurry vision, light sensitivity, and floating dark spots may develop and progress rapidly. If not treated, Uveitis can result in blindness.
Uveitis can be further defined by the location of the inflammation within the eye. If the swelling and redness involve the iris, it would be classified as Anterior Uvetitis, as the iris is known as the anterior chamber of the eye. Up to 90% of all uveitis cases involve this portion of the eye. Often called iritis, this includes episodes of blurriness or decreased vision, pink eye, drainage from the corners of the eye, and pain in the eye.
Inflammation involving the tissue in the middle layer of the eye if defined as Intermediate Uveitis and may sometimes be called Pars Planitis. Inflammation in this portion of the eye can result in more significant loss of vision as it is here that the cellular membranes targeted with covering and protecting the eye are affected.
When the swelling and inflammation involve the connective tissue and blood vessels in the back portion of the uvea it is known as Choroiditis or Posterior Uveitis. This is generally related to an immune system malfunction as part of a larger systemic condition such as might occur with eczema or psoriasis. If all layers of connective tissue within the uvea are affected the condition would be more correctly defined as Pan-uveitis.
Treatment would involve attention to ocular hygiene and careful cleansing of the eye, avoiding unnecessary touching of the eye or eye area, and in some cases treatment with an antibiotic solution or mineral based treatment with Rosacea-Ltd can speed the recovery time.
