# What is posterior uveitis?

Posterior uveitis is inflammation at the back of the eye, affecting the retina and choroid.

## What happens in posterior uveitis?

This condition can blur vision and cause floating spots called floaters. It may develop suddenly or gradually, and sometimes occurs in only one eye.

- Inflammation affects the light-sensing retina and its supporting layer
- Vision may become misty or patchy, especially for reading or detailed tasks
- Floaters can look like cobwebs or dark specks drifting across sight
- Some patients notice light sensitivity or mild eye discomfort

## When to seek help

Posterior [uveitis](https://bluefinvision.com/blog/what-is-uveitis-understanding-this-complex-eye-condition/) should always be checked promptly because it can scar the retina. Early treatment reduces the risk of lasting vision loss and helps keep daily activities manageable.

- Arrange an urgent eye assessment if you notice sudden blur or new floaters
- Tell the specialist about any autoimmune disease or recent infections
- Follow treatment carefully, which may include steroid drops, tablets, or injections
- Attend regular follow-up scans so any flare-up is spotted early
