Summary
A nonblast corneal injury caused a unique ring-shaped disruption of endothelial cells, visualized with corneal optical coherence tomography (OCT). The injury resolved spontaneously, demonstrating transient stromal edema.
Area of Science:
- Ophthalmology
- Corneal Imaging
- Traumatic Eye Injury
Background:
- Corneal endothelial rings are rare, often associated with blast injuries.
- Nonblast mechanisms for such injuries are less understood.
- Optical coherence tomography (OCT) is a valuable tool for visualizing corneal structures.
Observation:
- A 59-year-old male presented with a grey-white, annular corneal lesion after a nonpenetrating foreign body injury.
- Slit-lamp examination revealed a 3.3 mm diameter endothelial ring.
- Corneal OCT demonstrated stromal edema and endothelial disruption.
Findings:
- The corneal OCT findings confirmed a traumatic corneal endothelial ring.
- The observed pattern suggests a concussive injury mechanism.
- Stromal edema was localized anterior to the disrupted endothelial cells.
Implications:
- This case highlights a novel presentation of traumatic corneal injury.
- Corneal OCT is effective in diagnosing and monitoring such conditions.
- Findings support animal study hypotheses on injury mechanisms and sequelae.
