Summary
Penetrating keratoplasty (PKP) in children shows a 66.7% graft clarity rate, with earlier surgery recommended to prevent amblyopia and cosmetic issues. Endothelial immune rejection is a key factor in graft failure.
Area of Science:
- Ophthalmology
- Pediatric surgery
Context:
- Corneal opacities in children present unique surgical challenges.
- Penetrating keratoplasty (PKP) is a potential treatment for pediatric corneal blindness.
Purpose:
- To evaluate operative techniques for pediatric PKP.
- To identify factors influencing graft clarity after PKP in children.
Summary:
- PKP was performed on 33 eyes in 30 children, with follow-up from 6 months to 3 years.
- Graft clarity was achieved in 66.7% of cases, and 44.8% experienced visual rehabilitation.
- Congenital corneal opacity and endothelial immune rejection were associated with poorer outcomes and graft failure.
Impact:
- Early PKP in children is crucial for preventing amblyopia and addressing cosmetic concerns, despite generally poorer results compared to adults.
- Understanding graft failure mechanisms, particularly immune rejection, can guide future treatment strategies.
