# Posterior uveitis

Posterior uveitis is inflammation affecting the back of the eye, including the retina and choroid. It often causes floaters and blurred vision rather than obvious redness.

## How posterior uveitis presents

Because the inflammation is deep, the eye surface may look normal. Patients notice changes in sight more than discomfort.

- Symptoms include misty vision, floaters, and sometimes distorted images.
- Both eyes can be involved, often asymmetrically.
- Autoimmune disease, infections, or inflammatory conditions may be responsible.
- Examination with dilated pupils reveals retinal and choroidal lesions.
- Imaging such as OCT and angiography helps monitor activity.

## Treatment and prognosis

Control of inflammation is vital to prevent scarring and macular damage. Treatment is often more intensive and longer term than for simple anterior uveitis.

- Steroid tablets, injections, or implants are frequently required.
- Immunosuppressive drugs help reduce steroid side effects.
- Regular blood tests monitor safety of systemic treatments.
- Prompt treatment of flare-ups protects long-term vision.
- Close coordination with rheumatology or infectious disease teams is common.
