A staphyloma is an abnormal protrusion of the uveal tissue through a weak point in the eyeball. The protrusion is generally black in colour, due to the inner layers of the eye. It occurs due to weakening of outer layer of eye (cornea or sclera) by an inflammatory or degenerative condition. It may be of five types, depending on the location on the eyeball (bulbus oculi).

== Anterior (corneal) staphyloma == thumb|Anterior staphyloma after fungal corneal ulcer. In the anterior segment of the eye, involving the cornea and the nearby sclera. It is an ectasia and outpouching of the pseudocornea ( the scar formed from organised exudates and fibrous tissue covered with epithelium over the iris) which results after total sloughing of cornea in sloughening corneal ulcer with iris plastered behind; the pseudocornea, being too weak to resist the IOP protrudes forward with the uveal tissue. This is known as anterior staphyloma.
