Summary
A rare corneal condition caused by multiple surgeries showed epithelial-like cells with nuclei at the graft periphery. This finding offers new insights into graft failure mechanisms in penetrating keratoplasty patients.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Confocal Microscopy
Background:
- A 43-year-old female patient with a history of four penetrating keratoplasties presented with a concentric retrocorneal membrane.
- The membrane was located at the periphery of the corneal graft in her right eye.
Observation:
- In vivo examination using a white-light, tandem, scanning confocal microscope was performed on the affected eye.
- Confocal microscopy revealed structures resembling corneal epithelial cells at the endothelial layer of the graft periphery.
Findings:
- The observed cells, unlike typical corneal endothelial cells, possessed clearly identifiable nuclei.
- These findings suggest a potential cellular metaplasia or an unusual cellular response within the corneal graft.
Implications:
- This case highlights an uncommon presentation following multiple corneal surgeries.
- The presence of epithelial-like cells with nuclei may offer insights into the pathogenesis of graft failure and the development of retrocorneal membranes.
- Further research is warranted to understand the long-term implications and management of such conditions.
