Staphylus (Greek) means "cluster of grapes," and staphyloma gets its name from this. In a staphyloma, the wall of the globe (cornea or sclera) is ectatic and thin and bulging with uveal tissue, giving it a pigmented appearance. Anterior staphylomas occur mostly as a response to trauma or infection in which the scleral architecture has been disturbed and the internal pressure of the eye stretches the weak point, causing the protrusion and typical appearance. Rarely, staphylomas can be caused by surgical weakening of the sclera at some point. There is no specific treatment for this condition.
