BACKGROUND After simple excision without additional surgical measures, pterygiums demonstrate high recurrence rates. According to the literature, recurrences may occur in up to 83% after simple excision compared to 5-21% after excision combined with conjunctival autografts. An alternative to the free conjunctival graft is the sliding conjunctival graft. METHODS The data of 50 patients operated over a period of 8 years were evaluated retrospectively. The long-term results after pterygium excision with free conjunctival graft vs sliding conjunctival flap were compared with data extracted from the literature. RESULTS The average follow-up was 23 months. During this period, 18.5% of 27 operated eyes with free conjunctival grafts developed a recurrence of pterygium. After excision with sliding conjunctival grafts only 6.9% of 29 operated and examined eyes developed recurrences. CONCLUSIONS In the present study pterygium excision combined with sliding conjunctival graft was a simplified surgical technique with a lower recurrence rate compared to the free conjunctival graft.
