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 recognized. As opposed to coloboma, staphyloma defect is located off-center from the optic disc, typically temporal to the disc 3.
Patients often present with severe axial myopia 3.
It is an acquired defect secondary to weakness and thinning of the scleral-uveal coats 3.
- progressive myopia (or mega myope) is the most common cause
- necrotizing infection
Seen secondary to inflammation or infection of the sclero-corneal lining of the eye.
- increased eye size
- focal deformity (not as marked as coloboma), usually posterior
- non-enhancing uveo-sclera
