Disease Entity


Only a handful of cases have been reported on Ascher ring. It was first described by Dr Ascher in Germany in 1964.


Initially, these opacification were believed to be a result of an immunologic reaction as some patients with this entity had ocular history of unilateral idiopathic iritis. However, newer considerations suggest that the opacities are extracellular material likely deposited along a centripetal gradient.



On slit lamp examination, intrastromal (of varying depths) mid-peripheral symmetric bilateral corneal rings are observed. There are no associated inheritance patterns or systemic pathologies.


Corneal stromal opacification is visualized on OCT. Confocal microscopy shows reflective extracellular deposits.



The prognosis is very good for Ascher ring.
