Staphyloma

Staphyloma corneae

As staphyloma (synonym: Beer tumor, from Greek: staphyle = " grape " ) is called a morbid, " berry-like " protrusion of the cornea ( cornea) or the sclera ( sclera ) of the eye due to a dilution of the tissue. It can be congenital or acquired, also occur on one side or both sides. There are different types and causes:

  • Staphyloma anterior congenitum - severe, congenital form with the participation of the cornea and other sections of the eyeball
  • Equatorial staphyloma - the protrusion of the area behind the ciliary body
  • Ciliary staphyloma - the bulging of the sclera in the region of the ciliary body, for example, with increased intraocular pressure, or scleritis
  • Staphyloma corneae - the bulging of the cornea, for example, in iris prolapse or corneal inflammation
  • Staphyloma conicum - Hornhautstaphylom, which also forward portions of the choroid are affected

Because of the thinning of the tissue, the choroid ( Uvea) shimmers often dark to bluish round, which also explains the term Beer tumor.
