Diabetes-related Uveitis

Uveitis Overview

Uveitis is a group of disorders that cause inflammation inside the eye. The inflammation affects the middle section of the eye (known as the uvea or uveal tract), which comprises:

• The iris – the coloured part of the eye
• Choroid – the layer of tissue that supports the retina and contains the eye’s blood supply
• Ciliary body – the ring of muscle behind the retina that helps the eye focus by controlling the lens

Inflammation due to uveitis is not just limited to the retina but also affects other structures in the eye, including the vitreous, and optic nerve ²⁶.
