Uveitis is the inflammation of the uvea, the middle layer of your eye. The eye is shaped much like a ball, with three different layers of tissue surrounding a central gel-filled cavity. The inner most layer is the retina, which senses light and helps to send images to you brain. The middle layer between the sclera and the retina is called the uvea. The outer most layer is called the sclera, the strong white wall of the eye which is for protecting the eye specialist in Ahmedabad.
The uvea contains many blood vessels, the veins and the arteries that carry blood flow to the eye. Since it nourishes many important parts of the eye (such as the retina), inflammation of the uvea can damage your site. The Eye receives the maximum supply of blood in the body after the brain.
Uveitis may come on suddenly with the redness and pain, or sometimes with painless blurring of your vision. It can be a potential blinding of the eye if left untreated.
A case of simple "red eye" may in fact be serious problem of the uveitis. If your eye becomes red or painful, and does not clear up quickly, you should be examined and treated by an ophthalmologist. Hence never ignore a red eye with reduction in vision as it may be a harbinger sight threatening disease.
Uveitis has many different causes:
A virus, such as shingles, mumps or herpes
A fungus, such as histoplasmosis:
A parasite, such as toxoplasmosis:
Related disease in other parts of the body, such as arthritis:
A result of injury to the eye. Inflammation in one eye can result from a severe injury to the opposite eye (sympathetic uveitis):
Bacteria, such as syphilis.
In most cases of uveitis, the cause remains unknown. Almost 80% of the cases no cause may be found inspite of undergoing a battery of investigation.
