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.

  • Episcleritis goes away on its own, but corticosteroid eye drops may make symptoms go away quicker.

Additional symptoms include eye tenderness and irritation, with slightly increased watering of the eye and mildly increased sensitivity to bright light. The condition tends to disappear and may recur. The diagnosis is based on the symptoms and on the appearance of the eye.

Treatment of Episcleritis

  • Sometimes corticosteroid eye drops or nonsteroidal anti-inflammatory drugs by mouth

Treatment of episcleritis is often unnecessary. Eye drops that constrict blood vessels of the eye, such as tetrahydrozoline, can temporarily decrease the redness. However, these drops should be used only on special occasions because regular use leads to even more redness (called a rebound effect).

To treat an attack, corticosteroid eye drops or a nonsteroidal anti-inflammatory drug taken by mouth can be used to make symptoms go away quicker.
