Uveitis

Macular edema is a swelling of the macula, the part of the eye responsible for central vision. When fluid builds up in the macula, it becomes swollen and thicker. This distorts vision. There are several causes, including diabetic retinopathy, post-eye surgery complications, macular degeneration, injury, systemic inflammatory diseases that can affect the eye, and/or vein blockages. If an eye disease causes damage to blood vessels in the retina, it can cause macular edema. Left untreated, this problem can cause serious vision loss and even blindness.

Iritis is a common diagnosis that literally means “inflammation of the iris,” the colored part of the eye. Anterior uveitis is a more technical term for iritis. There are many possible causes, and sometimes the cause cannot be identified. Due to the complexity of the vision system, any suspected case of eye inflammation should be examined by an optometrist, ophthalmologist or medical doctor. Most of the time, iritis resolves in less than 6 weeks; however, iritis can reoccur. It can signal  acute or chronic underlying disease in the body, and therefore should be cared for by a qualified healthcare professional. Without proper treatment, iritis can lead to cataracts, glaucoma, an irregularly sized and sluggish pupil, calcium deposits in the cornea, central serous choroidopathy, or retinal swelling (cystoid macular edema).

Everyone is sensitive to light to some degree, but light sensitivity, or photophobia is an abnormal intolerance for light. Discomfort can be experienced from light sources such as sunlight and fluorescent or other artificial lights. It may cause the person with light sensitivity to squint or to have to close their eyes. It can cause pain and/or tears. In some cases, this may be accompanied by a headache.

The brighter the light, the greater the discomfort. Generally people

An enzyme acts as a catalyst to increase the rate of a chemical reaction. Enzymes are proteins. Scientists have named 3,000+ different enzymes, but perhaps 50,000 additional enzymes may exist. Enzymes all have specific functions that result in biochemical reactions. For example, certain enzymes are involved in the absorption of oxygen and production of energy; other enzymes help nutrients get into the cells.

Digestive enzymes produced by the pancreas are the most well-known, because they help break down food. Tay-Sachs disease and juvenile diabetes (Type I) are caused by genetic problems that inhibit the pancreas’s ability to generate the necessary enzymes in enough quantity.

Uveitis in Children

Uveitis means “inflammation of the uvea,” an inner layer of the eye, that can result in severe and permanent vision loss. In addition, uveitis can lead to other ocular complications including glaucoma, cataracts, or retinal damage all of which can severely damage the eyes. Early detection and treatment is necessary to reduce the risk of permanent vision loss.

A study published in the British Journal of Ophthalmology examines cases of the condition in children.  The study found that the younger a child is when he develops the disease, the more likely he is to have complications.
