Staphyloma is the term given to an eye whose scleral-uveal coats are stretched with uveal protrusion. This most commonly occurs posteriorly, although anterior staphyloma also is recognised. As opposed to coloboma, staphyloma defect is located off-center from the optic disc, typically temporal to the disc 3.
