Episcleritis is a relatively common inflammatory condition that affects the episclera, a thin layer of tissue between the conjunctiva and the sclera (the white part of the eye). Episcleritis can be categorized as simple or nodular, depending on the appearance of the inflammation. The exact cause is often unknown, but it may be associated with autoimmune disorders, allergies, or infections.

Symptoms
It typically presents as localized redness and mild eye discomfort, which may be aggravated by blinking or touching the eye.

Treatment
Treatment involves the use of lubricating eye drops, cool compresses, and occasionally, anti-inflammatory medications prescribed by an eye care professional. Most cases of episcleritis resolve within a few weeks.
