Spontaneous corneal perforation in pellucid marginal degeneration
1Department of Ophthalmology, University of Pennsylvania School of Medicine, Scheie Eye Institute, Philadelphia 19104, USA.
Summary
Spontaneous corneal perforation, though rare in pellucid marginal corneal degeneration, can occur. Prompt surgical repair with a patch graft can stabilize the cornea long-term.
Area of Science:
- Ophthalmology
- Corneal Diseases
- Ocular Surgery
Background:
- Pellucid marginal corneal degeneration (PMCD) is a rare, bilateral, progressive thinning of the peripheral cornea.
- Corneal ectasias, like PMCD, can predispose patients to various complications, including perforation.
Observation:
- A 74-year-old male with PMCD presented with spontaneous corneal perforation.
- The perforation was located in the peripheral cornea, a common site for PMCD-related thinning.
Findings:
- The corneal perforation was successfully managed with a 3 mm penetrating patch graft.
- The graft remained stable, and the patient showed no further progression of corneal ectasia in either eye for 7 years post-surgery.
Implications:
- This case highlights that spontaneous corneal perforation is a potential, albeit rare, complication of PMCD.
- Patients with PMCD should be informed about this risk, and prompt surgical intervention is crucial for favorable outcomes.
