Posterior uveitis is inflammation of the back segment of the uvea. The uvea is the middle layer of the eye. Posterior uveitis affects the retina and choroid, which are layers found in the back of the eye. The retina has the rods and cones that allow you to see.
Posterior uveitis is a potentially serious condition. Posterior uveitis requires care from your doctor to prevent vision loss.
Posterior uveitis may be caused by infection or by autoimmune disorders. It may also appear as a result of an infection in the past.
Factors that may increase your chance of posterior uveitis include:
- Autoimmune disorders, such as:
- Infections, such as:
- Weak immune status
- Exposure to pets, raw or undercooked meat, or contaminated water
- HLA-A29 gene
Posterior uveitis may cause:
- Blurred or loss of vision
- Seeing floating objects in your vision
- Sensitivity to light or glare
- Redness in the eye
- Excessive tearing
- Sensation of sparks or flashes of light
- Impaired night vision
- Impaired color vision
- Distortion of objects
You will be asked about your symptoms and medical history. A physical exam will be done.
To prepare for a complete eye exam, drops may be put in your eyes to numb them and to dilate your pupils. The slit lamp, a special microscope to examine the eye, will focus a high-powered beam of light into your eye to examine the cornea and other eye structures. The doctor may measure the pressure in your eyes.
Your bodily fluids may be tested to determine a possible cause. This can be done with blood tests.
Treatment will focus on relieving the symptoms of posterior uveitis until it goes away. It is important to follow treatment recommendations to prevent complications or recurrence.
The underlying cause will also be treated.
Posterior uveitis may be treated with:
- Oral or corticosteroid injections to control inflammation
- Medications to treat infection (if present)
- Medications that suppress the effects of the immune system
- Biological response modifiers to change immune response
