Staphyloma corneae

ICD-10 online (WHO version 2019)

As Staphyloma (synonym: Beer tumor from Greek staphyle = "bunch of grapes") refers to a pathological, "beer-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, and it can also occur unilaterally and bilaterally. There are different forms and causes:

  • Staphyloma anterius congenitum - severe, congenital form involving the cornea and other sections of the eyeball
  • Staphyloma aequatoriale - the protrusion of the area behind the ciliary body
  • Staphyloma ciliare - the protrusion of the sclera in the area of ​​the ciliary body, for example with increased intraocular pressure or scleritis
  • Staphyloma corneae - the protrusion of the cornea, e.g. in the case of iris prolapse or corneal inflammation
  • Staphyloma conicum - corneal staphyloma that also affects anterior sections of the choroid
  • Staphyloma verum posticum - the degenerative bulge of the sclera at the posterior pole, e.g. in the case of high myopia .

Because of the thinning of the tissue, the choroid ( uvea ) often shimmers dark to bluish, which also explains the term berry swelling .
