To report a case of spontaneous (nontraumatic) rupture of the cornea 7 days after intrastromal ring segment surgery in a patient with pellucid marginal degeneration (PMD).


Case report.


A 37-year-old African woman complains blurred vision, photophobia, foreign body sensation and redness in her left eye 7 days after an uneventful implantation of a Ferrara intrastromal corneal ring segment (ICRS) for PMD. Left eye examination revealed the rupture in the thinnest point of the cornea between the limbus and the implanted lower ICRS, and the iris prolapsed through the wound.


To the best of our knowledge, this case is the first documented spontaneous rupture of the thinnest point of the cornea in a patient with PMD treated successfully with the ICRS procedure. We examined the causes of this early and dramatic evolution and emphasize the importance of a careful follow-up.
