Retinitis
Retinitis
Retinitis (/rɛtɪˈnaɪtɪs/) is a medical term used to describe inflammation of the retina, the light-sensitive layer of tissue at the back of the eye.
Etymology
The term "retinitis" is derived from the Latin "retina", meaning "net", and the Greek "-itis", a common suffix used in medicine to denote inflammation.
Definition
Retinitis is a condition characterized by the inflammation and possible damage to the retina. It can be caused by various factors, including infections, autoimmune diseases, and genetic disorders. Symptoms may include blurred vision, floaters, and loss of peripheral vision.
Causes
Retinitis can be caused by a variety of factors, including:
- Infections: Certain viral, bacterial, or parasitic infections can lead to retinitis. For example, cytomegalovirus retinitis is a serious eye infection often seen in people with advanced HIV or AIDS.
- Autoimmune diseases: Conditions such as lupus or rheumatoid arthritis can cause inflammation in various parts of the body, including the retina.
- Genetic disorders: Certain genetic conditions, such as Retinitis Pigmentosa, can cause retinitis.
Treatment
Treatment for retinitis depends on the underlying cause. This may include antiviral or antibiotic medications for infections, immunosuppressive drugs for autoimmune conditions, or gene therapy for genetic disorders. In some cases, surgery may be necessary.
