==Overview==
Episcleritis is an acute, recurrent, benign inflammatory condition of the episclera, loose connective tissue lying superficial to the sclera. It has been recognized for more than a century and a number of recent studies have provided information about its clinical features, aetiology, and management. Episcleritis is overwhelmingly a disease of adults with a broad age range at presentation; childhood involvement is distinctly uncommon.1–3  The sex distribution varies between published series but those series that describe an association with rheumatic diseases tend to have a female preponderance. Episcleritis is uncommon and the exact incidence of episcleritis is difficult to know but, of 9600 new referrals to two eye departments in Glasgow between 1966 and 1974, only eight (0.08%) were due to scleral inflammation.4  In the same paper of 4210 patients with rheumatoid arthritis, only 0.17% had episcleritis at any stage of their disease. Diffuse episcleritis is more common than nodular episcleritis (78:16 in one series).5  Episcleritis is far commoner than the series in the medical literature would suggest. The majority of patients with episcleritis have mild evanescent disease that usually does not require ophthalmological intervention and treatment.6

==Causes==
==Clinical Features==
Disease name] may be caused by [cause1], [cause2], or [cause3].
The onset of episcleritis is usually acute and associated with discomfort as the presenting symptom. The pain is usually mild discomfort and localized to the eye, rather than boring in nature and associated with severe headache as is typical of scleritis.  Some episodes of episcleritis may be entirely pain free. There may be associated foreign body sensation and  The hallmark signs of episcleritis are oedema and inflammation of the episclera and injection and dilatation of the episcleral blood vessels. The sclera and subtarsal conjunctiva are not involved but the conjunctiva overlying the inflamed area is always affected. There is no scleral swelling or necrosis and the intraocular structures are typically not involved. Unless there is other coexistent ocular pathology the visual acuity is normal. Episcleritis is divided into diffuse and nodular types . In diffuse episcleritis  there is diffuse swelling and oedema of a sector of the episclera in around two-thirds of patients or of the whole eye in around one-third of patients. In diffuse episcleritis the redness varies in intensity, but is always red or pink (rather than the bluish, brawny red colour seen in diffuse scleritis), and the episcleral vessels, although engorged, retain their characteristic radial orientation. The best way of appreciating the colour of episcleritis and in particular differentiating it from scleritis is not to use the slit lamp but to examine the eye using natural light or an incandescent lamp. The eye is generally not tender to touch. In nodular episcleritis , the oedema and infiltration is localized to one part of the globe. A raised nodule forms within the episcleral tissue. It is bright red to pink in colour and often has overlying or surrounding vascular irregularity. The nodule may be tender to touch and is usually mobile. There is generally only one nodule at any one time and the nodules do not undergo necrosis. Careful slit lamp examination of the episclera, sclera, and the blood vessels is essential to differentiate episcleritis from scleritis.In patients with episcleritis there is oedema of the episclera and dilatation of the conjunctival vessels. There is no oedema of the underlying sclera. The lack of scleral involvement is often easiest to appreciate using red-free light and after blanching the superficial conjunctival vessels with phenylephrine 10%. After an attack of episcleritis the eye returns completely to normal, but after repeated attacks over a long period of time there may be some mild scleral thinning.
