Jenny, age 30, is worried about her left eye because it has been red and mildly irritated for the past 7 days. She tried chlorsig from the chemist but there was no improvement. On examination, there is localised redness of a segment of the left eye. Acuity is normal. There is no evidence of a foreign body and fluorescein examination is normal. Jenny is otherwise well.
Episcleritis. This can be idiopathic, or sometimes associated with autoimmune diseases like Crohn's or ulcerative colitis. It can be recurrent but is usually self limiting. Compared to scleritis, there is usually less pain and there are fewer associated symptoms such as photophobia / reduced vision. Scleritis is also more commonly associated with autoimmune disease.
