Treatment of choice for Pars planitis (Intermediateuveitis) –
**Core Concept**
Pars planitis, also known as intermediate uveitis, is a form of uveitis that affects the pars plana, a region between the ciliary body and the sclera. It is characterized by inflammation of the vitreous and is often associated with autoimmune disorders.
**Why the Correct Answer is Right**
The treatment of choice for pars planitis typically involves the use of corticosteroids to reduce inflammation. This can be achieved through topical or systemic administration of corticosteroids, or through the use of corticosteroid injections into the eye. In severe cases, immunosuppressive therapy may be necessary to control the inflammation. The pars plana vitrectomy (PPV) may also be required in some cases to remove the inflammatory cells and debris from the vitreous.
**Why Each Wrong Option is Incorrect**
**Option A:** Non-steroidal anti-inflammatory drugs (NSAIDs) are not effective in treating the underlying inflammation of pars planitis.
**Option B:** Topical antibiotics are not indicated for the treatment of pars planitis, as it is not caused by a bacterial infection.
**Option C:** Systemic antiviral medications are not typically used to treat pars planitis, as it is not caused by a viral infection.
**Clinical Pearl / High-Yield Fact**
Pars planitis is often associated with other autoimmune disorders, such as multiple sclerosis, ankylosing spondylitis, and rheumatoid arthritis. A thorough systemic evaluation is essential in the management of pars planitis.
**Correct Answer:** C. Corticosteroids.
