Introduction: Pterygium is a common degenerative conjunctival disease, for which several surgical
techniques were adopted, but none proved to be ideal because of the relatively high recurrence rate
after removal.
Objective: the primary outcome measure was to assess the recurrence rate of pterygia after surgical
removal with conjunctival-limbal transplantation; secondary outcome measure was to assess safety of
the procedure.
Method: study design: a prospective interventional study
Selection of 20 cases of advanced fleshy pterygia with at least 3.5 mm horizontal extension on the
cornea, some primary and some with multiple recurrences, surgical removal with conjunctival-limbal
autografting was done
Then postoperative fellow up for 3-6 years checking:
1-evidence of recurrence.
2-evidence of limbal stem cell deficiency.
Results: mean age was 53.45+- 15.78 year
After surgery, the minimum fellow up period was 3 years for primary pterygia, and 6 years for
recurrent pterygia
NO recurrence was observed during that period; in addition no signs of limbal stem cell deficiency
were seen.
Conclusion: Surgical removal with conjunctival-limbal transplantation proved to be safe and effective
for both primary and recurrent pterygia, with NO recurrence rate.
