PATHOLOGY

Detailed explanation-1: -Scleritis is the inflammation in the episcleral and scleral tissues with injection in both superficial and deep episcleral vessels. It may involve the cornea, adjacent episclera and the uvea and thus can be vision-threatening. Scleritis is often associated with an underlying systemic disease in up to 50% of patients.

Detailed explanation-2: -Scleritis is a disorder in which the sclera becomes severely inflamed and red. It can be very painful. Scleritis is believed to be the result of the body’s immune system overreacting.

Detailed explanation-3: -Episcleritis is inflammation of the tissue lying between the sclera (the tough, white, fiber layer covering the eye) and the conjunctiva (the membrane that lines the eyelid and covers the white of the eye). The cause is usually unknown. Symptoms include eye redness, swelling, and irritation.
