Eye Inflammation Can Cause Blindness
Inflammation in the back of the eye is estimated to cause up to 10 percent of all cases of blindness. When the choroid and retina in the eye become inflamed, the condition is known as chorioretinitis.
Anatomy of the Eye
The inner lining of the eye is a light-sensitive layer of tissue known as the retina. The retina receives images that pass into the eye through the lens and converts them to electric signals that are sent to the brain. The outer layer of the eye is the white portion known as the sclera. Sandwiched between the sclera and the retina is the choroid – a layer of blood vessels that supply nutrients to the retina and other parts of the back of the eye.
If the choroid layer of the eye becomes inflamed, the condition is known as choroiditis. If both the retina and choroid are inflamed, the condition is called chorioretinis. These conditions along with other types of inflammation in the back of the eye can also be called uveitis.
Risk Factors
Chorioretinitis is often associated with other conditions affecting the entire body, not just the eyes. People with these conditions may be at higher risk for chorioretinis or other forms of uveitis:
• Infections including syphilis and tuberculosis
• Autoimmune disorders such as rheumatoid arthritis, sarcoidosis, or HIV/AIDS
• Eye injury
• Cancer
• Exposure to toxins including acids and some pesticides
Chorioretinitis can also occur with no apparent cause, and some cases appear to be the result of an infection that took place many years prior to the inflammation in the eye.
Symptoms
Chorioretinitis shares the same symptoms with a variety of other eye conditions. These symptoms may or may not mean that you have chorioretinitis. See your eye care professional if you have:
• Eye pain
• Eye redness
• Blurred vision
• Floaters in your vision
• New sensitivity to light
• Excessive tearing
Treatments
Depending on the cause and severity of the inflammation, chorioretinitis can cause permanent damage to vision if left untreated.
