Summary
Limbal transplantation (LT) using autografts is more successful than allografts for treating limbal stem cell deficiency (LSCD). Autografts avoid systemic immunosuppression and offer better outcomes, especially for pterygium cases.
Area of Science:
- Ophthalmology
- Regenerative Medicine
- Transplantation Surgery
Background:
- Limbal stem cell deficiency (LSCD) is a severe ocular surface disease.
- Limbal transplantation (LT) aims to restore the ocular surface epithelium.
- Previous studies highlight varying success rates for LT.
Purpose of the Study:
- To evaluate the outcomes of limbal transplantation (LT) in patients with limbal stem cell deficiency (LSCD).
- To compare the efficacy of autografts versus allografts in LT procedures.
- To identify factors influencing LT success in ocular surface diseases.
Main Methods:
- A retrospective multicenter case series analysis of 72 LT procedures performed between 1996 and 2004.
- Data collected from 61 patients with LSCD across 5 centers.
- Success defined by absence of persistent epithelial defects, ongoing inflammation, or pterygium recurrence.
Main Results:
- Overall success rate for LT was 66.7% (48/72).
- Autografts achieved an 81.0% success rate, significantly higher than the 7.1% success rate for allografts.
- LT success was highest for pterygium (80.0%) and lowest for immune-based disorders (14.3%).
Conclusions:
- Autograft tissue is superior to allografts for LT in treating LSCD due to higher success rates and avoidance of immunosuppression.
- Immune-based disorders present the most challenging cases for LT.
- LT is a promising treatment for recurrent pterygium, warranting further prospective investigation.
