GFS was performed by a single surgeon on the right eye only. The surgeries were performed with the animals under general anesthesia by intramuscular injection of ketamine 50 mg/mL and xylazine 2%. The animals were randomly allocated into three groups according to the medications used during the surgery:
Group A:
bevacizumab (
Avastin ® , Genentech, San Francisco, CA, USA). Subconjunctival injection using a 27-gauge needle (1.25-0.05 mL), adjacent to the site of the surgery at the end of the procedure.
Group B: MMC (
Mitocin ® , Bristol-Myers Squibb, São Paulo, SP, Brazil) (0.2 mg/mL) soaked in a semilunar 8-mm diameter sponge (25.12 mm 2 area), placed between the Tenon capsule and sclera for 3 min, followed by continuous irrigation with 20 mL of balanced salt solution and subconjunctival injection of
bevacizumab as described above.
Group C: MMC application alone, as previously described.
