Summary
An 83-year-old experienced recurrent corneal epithelial dysplasia after abrasion. Treatment with mitomycin C resulted in a clear cornea with good vision, and human papillomavirus type 6 was identified.
Area of Science:
- Ophthalmology
- Corneal Diseases
- Epithelial Abnormalities
Background:
- Corneal epithelial dysplasia is a rare condition.
- Recurrence after initial injury is possible.
- Accurate diagnosis requires histological examination.
Observation:
- An 83-year-old presented with recurrent corneal epithelial dysplasia following a corneal abrasion.
- The lesion extended to involve the entire corneal epithelium, limbus, and conjunctiva.
- Biopsies confirmed stage 3 corneal epithelial dysplasia, with normal limbal and conjunctival epithelium.
Findings:
- Surgical resection followed by two cycles of topical mitomycin C was performed.
- Human papillomavirus type 6 was detected, a type not typically associated with malignancy.
- Nine months post-treatment, the cornea remained clear, and vision was preserved.
Implications:
- Topical mitomycin C can be an effective treatment for corneal epithelial dysplasia.
- Early diagnosis and intervention are crucial for preserving vision.
- The role of human papillomavirus in corneal epithelial dysplasia warrants further investigation.
