## **Core Concept**
Scleritis is a severe inflammatory eye disease characterized by inflammation of the sclera, which is the white outer wall of the eyeball. It can be caused by various factors, including autoimmune disorders, infections, and systemic diseases. Understanding the underlying causes is crucial for proper diagnosis and management.

## **Why the Correct Answer is Right**
The correct answer, , implies that scleritis can be caused by autoimmune disorders. This is accurate as conditions like rheumatoid arthritis, lupus, and granulomatosis with polyangiitis are known to cause scleritis. These autoimmune diseases lead to inflammation of the sclera through immune complex deposition and cell-mediated immunity.

## **Why Each Wrong Option is Incorrect**
* **Option A:** - This option suggests that scleritis is caused by a direct infection. While infections can cause scleritis, especially in cases of scleromalacia perforans or infectious scleritis, they are not the primary or most common cause.
* **Option B:** - This option implies a traumatic cause, which is not a typical etiology for scleritis. Trauma can lead to various ocular conditions but is not primarily associated with scleritis.
* **Option C:** - This option might suggest a neoplastic cause, which is extremely rare and not commonly associated with scleritis.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that scleritis is often associated with systemic autoimmune diseases. A thorough investigation for underlying conditions like rheumatoid arthritis or lupus is essential when diagnosing scleritis. Early recognition and treatment can prevent complications such as vision loss.

## **Correct Answer:** . Autoimmune disorders.
