Uveitis is also known as ocular inflammation. It refers to a condition where there is inflammation in the middle layer of the eye, called uvea. The inflammation can extend to the areas around the uvea like the retina, or the vitreous too. Working of a normal eye is similar to that of a camera. In a normal eye where the lens is clear, the light enters through the lens and focuses on the thin film called the retina located at the back of the eye. This light is then captured by the eye and signals are sent to the brain to form the image that we see.
