Summary

Purpose: To assess the efficacy and safety of a single preoperative intra-lesional bevacizumab injection in primary pterygium.

Methods: The investigators conducted a randomized controlled interventional study from January 2019 to December 2020. The study included a total of 60 patients (60 eyes) with primary pterygium. The investigators defined two groups of 30 patients each. Group A received an intralesional injection of bevacizumab (Avastin), one month before surgery (lesion excision and conjunctival autograft). Group B (control) had only the surgical treatment. Patients were followed up seven days (D7), one month (M1), three months (M3), and six months (M6) post-operatively. Pre-, per- and post-operatively, photographs of the lesions were taken, as well as a pathological examination. The main outcome measures were the change in functional discomfort following intralesional bevacizumab injection and pterygium recurrence. Recurrence was defined by fibrovascular tissue growth extending more than 1 mm across the limbus. Therapeutic success was defined as the absence of pterygium recurrence in M6.

Interventions

DRUG

Preoperative Intra-lesional Bevacizumab Injection in primary pterygium

The surgical technique featured: subconjunctival anesthetic (lidocaine 2%) injection 5 mm from limbus; excision of the pterygium, starting from its head, followed by pterygium body removal; exposition of a triangular-shaped bare scleral bed (3-4 mm) conjunctival autograft stitched limbus to limbus with 10/0 vicryl suture Any intraoperative complication was noted and was treated accordingly. All patients received dexamethasone + tobramycin eye drops postoperatively 4 times a day in the 1st week. The eye drops were tapered over 4 weeks. Patients were examined 30 days before bevacizumab injection (D-30), before surgery (day 0: D0) and then at D7, M1, M3, and M6 after surgery.

PROCEDURE

pterygium surgery without adjunctive therapy

The surgical technique featured: subconjunctival anesthetic (lidocaine 2%) injection 5 mm from limbus; excision of the pterygium, starting from its head, followed by pterygium body removal; exposition of a triangular-shaped bare scleral bed (3-4 mm) conjunctival autograft stitched limbus to limbus with 10/0 vicryl suture
